The PosiTector 6000 hand-held, electronic instrument non-destructively measures the thickness of coatings on metals, quickly and accurately. It consists of a body (Standard or Advanced) and probe (Built-in or Separate).

Principles of Operation
F probes use the magnetic principle to measure the thickness of non-magnetic coatings on ferrous metals.

N probes use the eddy current principle to measure the thickness of non-conductive coatings on non-ferrous metals.

FN probes combine the full abilities of both the "F" and "N" probes.

Quick Start

The PosiTector 6000 powers-up when the center navigation button is pressed. To preserve battery life, it powers-down after approximately 5 minutes of no activity. All settings are retained.

  1. Remove the protective plastic cap (if supplied) from probe. 

  2. Power-up Gage by pressing the center navigation button. 

  3. Place the probe FLAT on the surface to be measured. HOLD STEADY. When a valid measurement is calculated, the Gage BEEPS twice and the measurement is displayed.

  4. Lift probe AT LEAST 2 INCHES (5cm) from the surface between measurements - OR - leave probe on the surface in the same location for continuous measurements.
    If memory is ON while continuous measurements are being taken, only the last value on the display (when the probe is lifted) is stored into memory. Scan stores ALL measurements into memory.

Protective Cap
Some PosiTector 6000 models are shipped with a protective plastic cap over the probe. Remove this cap prior to use. Replace it when the instrument is not in use to protect the probe.

Wrist Strap
We recommend attaching and wearing the supplied wrist strap.

Plastic Lens Shield
The LCD is covered with a thin plastic film for protection against fingerprints and other marks during shipment. This film, while usually removed before using the instrument, can be left in place to protect against paint overspray. Replacements can be purchased.

Golden Rule

Measure your uncoated part first! This quick zero-check determines if a Calibration Adjustment is needed for your substrate.

Next, lay the included plastic shims onto a bare surface and measure them individually to ensure the Gage measures a known thickness within tolerance.


All probes include a Certificate of Calibration. For organizations with re-certification requirements, instruments may be returned at regular intervals for calibration. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from either the date of calibration, date of purchase, or date of receipt is a typical starting point. Written calibration procedures are available from DeFelsko Corporation at no charge.

lineMagnetic & Eddy Current - Theory of Operationline

The PosiTector 6000 probes calculate coating thickness measurements using either the magnetic principle (Fprobes - ferrous models)?or the eddy current principle (N probes - non-ferrous models). Combination FN probes (ferrous/non-ferrous) use both principles.

FN probes first attempt a measurement using the magnetic principle and will display a reading with the letter "F" if the coating is non-magnetic over steel. If the coating is non-conductive over metal, then the probe will automatically attempt a measurement using the eddy current principle and display a reading with the letter "N” (see also N Lock).


The PosiTector 6000 consists of a body and a probe. A wide selection of interchangeable probes are available. Each retain their own unique calibration information. All Gage bodies accept all probes. More probe information is available at www.defelsko.com/p6000/positector6000.htm

To disconnect, a probe from a body, power-down the instrument and pull the plastic probe connector horizontally (in the direction of the arrow) away from the body. Reverse these steps to attach a new probe.

When powered-up the PosiTector automatically determines what type of probe is attached and does a self-check. Coating thickness probes “sense” when they are near metal and immediately attempt a measurement followed by another every 2 seconds. They stop when removed from the vicinity of metal and power-down after 5 minutes of no activity.

This continuous measurement feature is intended to allow careful probe placement on small or odd-shaped surfaces. Ignore all readings taken before the probe is properly placed.

Two Probe Styles:

  • Built-in - sensor protrudes from bottom of probe connector
  • Separate - sensor is attached to the probe connector by a 1.2 meter (3 foot) cable. (Extended cables lengths available.)

Available PosiTector 6000 Probes:

lineWhy is Measurement Important?line

Dry film thickness (DFT) is arguably the single most important measurement made during the application and inspection of protective coatings. Coatings are designed to perform their intended function when applied within a tight DFT range as specified by the manufacturer. Correct thickness ensures optimum product performance. Even the most basic specification will require DFT to be measured.

Many physical and appearance properties of the finished coating are directly affected by the film thickness including the color, gloss, surface profile, adhesion, flexibility, impact resistance, and hardness of the coating. The fit of pieces assembled after coating can be affected when film thickness isn’t within tolerance.

Regular film thickness measurement helps control material costs, manage application efficiency, maintain finish quality and ensure compliance with contract specifications. Paint manufacturers recommend target ranges to achieve optimum performance characteristics and clients expect these parameters to be met.

Precisely measuring finish thickness has other benefits, too. Whether to meet International Organization for Standardization (ISO), quality, or customer requirements for process control, companies need to verify coating quality to avoid wasting money reworking product.

lineCalibration, Verification & Adjustmentline

The PosiTector 6000 non-destructively measures the thickness of coatings on metals. Three steps ensure best accuracy...

  1. Calibration - typically done by the manufacturer.?All probes include a Certificate of Calibration.
  2. Verification - typically done by the user on known reference standards such as plastic shims or coated thickness standards.
  3. Adjustment - to a known thickness

Calibration is the high-level, controlled and documented process of measuring traceable calibration standards over the full operating range of the probe, and verifying that the results are within the stated accuracy of the probe. Calibrations are performed by the manufacturer, their authorized agent, or by an accredited calibration laboratory in a controlled environment using a documented process.

PosiTector 6000 probes are shipped with a Certificate of Calibration showing traceability to a National Metrology Institution. For organizations with re-certification requirements, probes may be returned at regular intervals for calibration. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on DeFelsko’s product knowledge, data and customer feedback, a one year calibration interval from either the last date of calibration, date of purchase, or date of receipt is a typical starting point. Written Calibration Procedures are available online at no charge.

Verification is an accuracy check performed by the user using known reference standards. A successful verification requires the Gage to read within the combined accuracy of the probe and the reference

A reference standard is a sample of known thickness(es) against which a user may verify probe accuracy. Reference standards may be plastic shims, coated thickness standards, or sample parts whose coating thickness has been determined using other means.

Verify accuracy at the beginning and the end of each work shift. During the work shift, if the Gage is dropped or suspected of giving erroneous readings, its accuracy should be re-verified. In the event of physical damage, wear, high usage, or after an established calibration interval, the probe should be returned to the manufacturer for repair or calibration.

Adjustment, or Cal Adjustment, is the physical act of aligning the probe’s thickness readings to match those of a known thickness sample (removal of bias) in order to improve the accuracy of the probe on a specific surface or in a specific portion of its measurement range. 1-point or 2-point Cal adjustments are possible.

Probes are factory calibrated and perform an automatic self-check each time a measurement is taken. For many applications no further adjustment is necessary after a Reset. Just check ZERO on the uncoated substrate, then measure. However, sometimes probe readings can be influenced by changes in substrate shape, composition, and surface roughness or by measuring in a different location on the part. That is why Cal adjustments are made possible. The  symbol disappears whenever a Cal adjustment is made.

Where a Cal adjustment method has not been specified, use a 1-point method first. If measuring the included shims on your uncoated surface reveals inaccuracies, use the 2-point method. Factory Cal settings can be restored at any time by performing a Reset, creating a NEW Cal setting (See Cal Memory), or by DELETING the adjustments made to the Cal 1 calibration setting. The  symbol appears on the display whenever factory Cal settings are in use. With “FN” probes, calibration adjustments are made only to the “F” or “N” mode (stored independently under a particular Cal), whichever was measured last.

lineMenu Operation line

Instrument functions are menu controlled. To access the Menu, power-up the instrument, then press the center navigation button  .

Below is a sample menu for a PosiTector 6000 Advanced Model:

Navigation Button

To navigate, use the Up and Down buttons to scroll and to SELECT.

Select Exit to exit from any menu.

Cal Settings Menu

1-point Calibration Adjustment
Also known as an offset or correction value, there are 4 ways to perform this adjustment:

(i) Simple Zero Calibration Adjustment
Measure your uncoated part. If the Gage does not read "0" within the tolerance of the probe being used, lift the probe from the surface and adjust the display down (-) or up (+) until it reads "0". Measure and adjust until the average of a series of readings on the uncoated surface is within tolerance of "0".


(ii) Average Zero Calibration Adjustment
To establish “0” on a rough or curved surface a preferred method to (i) is to take several readings on the uncoated part and average the result.

(a) Select Zero from the Cal Settings menu.
(b) Press (+) to select the number of readings to be used to obtain an average, typically 3 to 10 readings. The greater the variation between readings, the more readings should be taken to obtain an average.
(c) Repeatedly measure the uncoated part. The Gage will wait 2 seconds after placing the probe on the surface to allow the user to correctly position the probe on the surface. After the last measurement the Gage will calculate a Zero which represents the average of all the Zero readings taken.

(iii) Simple Adjustment to a Known Thickness
It is sometimes desirable to adjust the Gage to a known thickness, such as a shim, rather than adjusting it to zero.

Measure the object. If the expected reading is not obtained (within tolerance), lift the probe from the surface and adjust the displayed reading down (-) or up (+) to the expected thickness. Hold the button down to increase the rate of adjustment.

line1 Pt Adjustline

(iv) Average Adjustment to a Known Thickness
On rough or curved surfaces a preferred method to (iii) is to take several readings on the known thickness and average the result.
(a) Select 1 Pt Adjust from the Cal Settings menu.
(b) Press (+) to select the number of readings to be used to obtain an average, typically 3 to 10 readings. The greater the variation between readings, the more readings should be taken to obtain an average.
(c) Repeatedly measure the known thickness reference. The Gage will wait 2 seconds between readings to allow the user to correctly position the probe on the surface. After the last measurement the Gage will calculate and display the reading which represents the average of all the measurements taken. If the expected reading is not obtained (within tolerance) lift the probe from the surface and adjust the reading down (-) or up (+) to the expected thickness and press. 

line2 Pt Adjustline

2-point Calibration Adjustment
Preferred method for very unusual substrate materials, shapes or conditions. Provides greater accuracy within a limited, defined range.

  1. Select 2 Pt Adjust from the Cal Settings menu.
  2. Press (+) to select the number of readings to be used to obtain an average on the thinner item, typically 3 to 10 readings. The greater the variation between readings, the more readings should be taken to obtain an average.
  3. Repeatedly measure the thinner item. The Gage will wait for 2 seconds on the surface to allow the user to correctly position the probe on the surface. After the last measurement the Gage will calculate and display
    a thickness value which represents the average of all the readings taken using the factory calibration settings.
  4. Lift the probe from the surface and adjust the displayed reading down (-) or up (+) to the known thickness value of the thin item. Press  to accept this value.
  5. Repeat steps 2 - 4 for the thicker item.

lineCal Lock line

When selected, the  icon will appear and all calibration settings are “locked” to prevent further user adjustments. Uncheck to make further adjustments.

lineN Lock  (FN ferrous/non-ferrous combination probes only)line
Select Non-Ferrous Lock (N Lock) when operating regularly on non-ferrous substrates. The  icon will appear and the probe will only use the eddy current principle to shorten measurement time and extend battery life.

N Lock is useful when measuring coatings on plated steel. Normally the probe measures both the coating + plating over the steel using the magnetic principle. N Lock makes the Gage measure the coating over the plating only.

Select N Lock to measure over slightly magnetic substrates; i.e. clear-coat on gold over nickel-plated brass. Although the probe’s magnet is used for the magnetic principle, it is also used in N Lock to magnetically saturate a slightly magnetic substrate and allow the eddy current principle to operate unhindered.

CAUTION: With N Lock engaged it is possible to obtain a reading when measuring non-conductive coatings on steel. This is not recommended.

lineCalibration Memory

Cal Memory (Advanced models only)

It is often convenient to store a particular calibration adjustment before making another. Then, if you return to that part, the corresponding calibration setting can be restored.

A “setting” is any calibration adjustment. The PosiTector 6000 always displays the current calibration setting (ex. Cal 3) in the upper right corner of the display.

The setting called Cal 1 has unique features. It can be adjusted but never deleted, and is always made active with factory settings after a Reset

Creates a new calibration setting using the next available number (Maximum of 10). By default, these new Cal settings are initially created with the Gage’s factory settings. This is indicated with the  icon which appears at the bottom of the display. A warning message will prevent the creation of a new Cal Memory if a batch
is open and has readings. Delete the batch first.

Loads an existing setting. Use the Up or Down buttons to scroll until the desired setting appears, then press. A warning message will prevent the opening of a stored Cal setting if a batch is open and has readings. Create a new batch first or open a batch containing no readings.

Removes a setting completely from the list. That Cal number can be reused later with the New command. A setting cannot be deleted if readings have been stored into a batch using that calibration setting. Delete all readings in that batch first. Although Cal 1 cannot be deleted, the Delete function will return it to factory settings.

View stored Calibration Settings.

lineSetup Menu Resetline

Reset (soft reset) restores factory settings and returns the instrument to a known condition. The following occurs:

  • All batches, stored measurements, images, and batch names are erased.
  • Menu settings are returned to the following:
    • Memory = OFF
    • High Res = OFF
    • Statistics Mode = OFF
    • Hi Lo Alarm = OFF
    • Scan Mode = OFF

Perform a more thorough Hard Reset by powering down the instrument, waiting several seconds, then simultaneously holding both the center  and (+) buttons until the Reset  symbol appears. This returns the instrument to a known “out-of-the-box” condition. It performs the same function as a menu Reset with addition of:

  • All calibration adjustments and Cal Memory are cleared and returned to the gage’s factory calibration settings.
  • Bluetooth Pairing info is cleared
  • Menu Settings are returned to the following:
    • Units = microns
    • Flip Display = Normal
    • Auto Sync = OFF
    • White on Black = OFF
    • Fast Mode = OFF
    • Language = English
    • Battery Type = Alkaline
    • Backlight = Normal
    • Bluetooth Streaming = OFF
    • USB Drive = ON


  • Keep the Gage away from metal during a Reset.
  • Date, Time and WiFi are not affected by a Reset.

lineGage Infoline

Displays the model number & serial number, probe type & serial number, PosiSoft.net registration key, the amount of remaining memory for storage of readings, date and time, and software packages.

For security purposes, the registration key is required to add the instrument to your free PosiSoft.net account.

lineHi Res line

Increases the displayed Gage resolution as follows:

Resolution Range

  • 0.01 mil 0.00 - 99.00 mils
  • 0.1 mil 100.0 - 999.9 mils
  • 0.1 um 0.0 - 999.9 um
  • 1.0 um over 1000 um

NOTE: Gage accuracy is not affected.

lineFast  line

Increases measurement speed for most probes. Useful for quick inspection or when measuring large areas with thick coatings where proper probe positioning is not critical. Swift up/down probe movement is required. Reduced accuracy may be noted.

Scan   (Advanced models only)

In ordinary operation, the PosiTector 6000 takes thickness measurements every 2 seconds when placed onto a surface. Normally, the user raises the probe after it has taken a single measurement and relocates it to a second location. Scan mode modifies this behavior in two ways. First, measurements are taken much faster. Second, all measurements are recorded when memory is on. As the probe slides along the surface in scan mode, the PosiTector 6000 takes single measurements in quick succession. This may reduce the life of the probe. Recommended for smooth surfaces only.

Flip Display
This option causes the display to read upside down. Ideal for use on a worktable (separate cable probes) and overhead (removable built-in probes) with the resultant display conveniently pointed toward the operator.

White on Black (Advanced models only)
Inverses the LCD display to white on a black background to provide better readability in some surroundings.

Backlight (Advanced models only)
Selects display brightness (Sun, Normal or Night). All settings will dim slightly after a period of no activity to conserve battery life. Press the Down button to brighten the display.

Set Clock
All batches are date-stamped when created, and all readings are time-stamped (24 hour format) when stored into memory. It is therefore important to keep both the date and time current using this menu option. Use the Up and Down buttons to scroll, and the (-) and (+) buttons to adjust a value. The instrument’s data and time can also be viewed in Info.

Battery Type
Selects the type of batteries used in the instrument from a choice of “Alkaline”, “Lithium” or “NiMH” (Nickel-metal hydride rechargeable). If NiMH is selected, the instrument will trickle charge the batteries while connected via USB to a PC or optional AC charger. The battery state indicator icon is calibrated for the selected battery type. No damage will occur if the wrong battery type is selected.

NOTE: DeFelsko recommends the use of eneloop (NiMH) rechargeable batteries.

Converts the display from inch to metric or vice versa. Stored measurements in memory are not converted.

NOTE: Switching units will turn off StatisticsHiLo Alarm, and closes Memory.

Remove the last measurement by pressing the (-) button. Press (+) to clear statistics.

lineHiLo Alarm line

Allows the Gage to visibly and audibly alert the user when measurements exceed user-specified limits.

When HiLo Alarm is selected, the current Lo setting is displayed. Adjust down (-) or up (+). Alternatively, measure a coating with a thickness close to the required value and make final adjustments with the buttons. Select NEXT to accept this value. The current Hi setting is now displayed. Follow the same procedure to adjust the Hi setting.

The icon  will appear on the display.

Measurements will be compared to your defined HiLo limits. The Gage beeps if results are within those limits. A single low tone will sound if the reading is below the Lo limit, and a high tone if it is above the Hi limit. Press (+) to clear HiLo readings.

Clears all on-screen Statistics and HiLo tabulations.

line Memory Management line

The PosiTector 6000 has internal memory storage for recording measurement data. Stored measurements can be reviewed on-screen or accessed via computers, tablets and smart phones. Measurements are date and time-stamped.

Standard models store up to 250 readings in one batch.

The Memory menu includes the following options...

  • On: turns memory on and begins recording
  • Off: stops recording (stored readings remain in memory)

Synchronizing (Sync) is the process whereby PosiTector stored measurement data uploads to PosiSoft.net (from both Standard and Advanced models) while images and batch notes are downloaded to the Gage (Advanced model only). This transfer occurs when the Gage is connected via USB, Bluetooth or directly through your WiFi router/hotspot via WiFi. It can be triggered either manually (USB, Bluetooth or WiFi) or automatically (USB only).

Sync Now
When selected, the Gage immediately synchronizes stored measurement data via USB, Bluetooth or WiFi to PosiSoft.net. (PosiSoft Desktop Manager and an internet connection are required when using USB?or Bluetooth.)

Multiple gages can be synchronized simultaneously when connected using multiple connections (for example two gages connected via USB and one gage connected via WiFi or Bluetooth).

lineAuto SYNC line

Allows the Gage to automatically synchronize stored measurements with PosiSoft.net when initially connected to the internet via a PC running PosiSoft Desktop Manager or a local WiFi network.

Additional measurements added to memory while connected are synchronized only when the USB cable is disconnected, then reconnected or when the Sync Now option is selected.

lineUSB Drive line

Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually a personal computer). USB has effectively replaced a variety of interfaces such as serial and parallel ports.

The PosiTector uses a USB mass storage device class which provides a simple interface to retrieve data in a manner similar to USB flash drives, cameras or digital audio players.

When checked, any computer can view datasets stored in memory by navigating a virtual drive labeled "PosiTector” using the included USB cable.

A formatted HTML report is viewed by selecting the "index.html" file found in the root directory. Optionally, text ".txt" files located in each batch folder provide access to measurement values. Stored datasets and graphs can be viewed or copied using universal PC/Mac web browsers or file explorers.

 When your PosiTector is first connected to your Windows PC via a USB cable, an enumeration process is started that installs device drivers without re-booting your computer. You may see several pop-up windows in the taskbar at the bottom right of your screen. Wait for the entire process to be completed before proceeding.

NOTE: When connected the power is supplied through the USB cable. The batteries are not used and the body will not automatically power down. If rechargeable (NiMH) batteries are installed, the instrument will trickle charge the batteries.

Retrieving stored screen captures:

The last 10 screen captures stored in memory can be accessed by navigating to the “screen_capture” directory within the “PosiTector” virtual drive.

Coating Thickness Standards
Certified Thickness Standards are used to verify the accuracy and operation of coating thickness gages and are an important component in fulfilling both ISO/QS-9000 and in-house quality control requirements. Contracts often specify that coating thickness measurements be taken by gages whose measurement accuracy is traceable to a National Metrology Institute such as NIST or PTB.

Standards are typically purchased as an accessory to coating thickness gages. Many customers find it more practical to verify the accuracy of their own gages in-house, rather than utilize DeFelsko’s calibration services. This is particularly true when many gages are in use and/or when accuracy verification is performed often.

There are 5 types of coating thickness standards available:

Certified Coated Metal Plates are the best solution for verifying the calibration, accuracy and operation of most magnetic, eddy current or ultrasonic coating thickness gages including magnetic pull-off gages as well as many competitive models. They fulfill both ISO and in-house quality control requirements. At ±0.43 ?m (±0.017 mil) solution.

Certified Polystyrene Blocks are for use with gages that measure over 1500 ?m (60 mils).

Certified Plastic Shims (foils) provide an economical alternative to coated metal plates. They have reduced accuracy of ±2 ?m (±0.08 mil). A coating thickness gage measures shim thickness when this shim is placed over a smooth metal surface (zero plate).

Non-Certified Plastic Shims (foils) provide a quick operational check of the instrument and they allow the user to perform practice measurements when placed over metal. They protect the probe from damage or premature wear when placed over hot or abrasive surfaces, and they can be placed on top of soft or tacky coating films to obtain thickness measurements without the gage probe depressing the coating film. A set of 5 shims is included with every PosiTector 6000.

Zero Plates are uncoated steel or aluminum disks. A zero plate is included with most coated metal sets. The first gage measurement is on a zero plate to verify that the gage measures zero correctly. Electronic gages can usually be adjusted to “0” if necessary. A zero plate is also a convenient base onto which a plastic shim or polystyrene block can be placed for measurement. Zero plates are also used to provide a substrate where none exists. Large sheets of material such as paper, plastic, fabric and rubber can be measured with a coating thickness gage by placing the material over the zero plate. This is useful when the measured item is too large to access with a micrometer or other device.

Most conditions can be cleared with a Hard Reset. If not, visit our Service & Support page for information on sending your instrument to us for a no charge evaluation.
See: http://www.defelsko.com/service

Probe attempts a measurement even while held in the air:
The probe may have been left near metal, including jewelry, during power up or at rest. Possibly a finger was held over the probe. Try measuring on an uncoated object. Otherwise turn the Gage off, and then on again. Finally try a reset.

Thickness readings are inconsistent:

  • Probe tip may be damaged, scratched or worn
  • Make sure you lift the probe well clear of the surface between measurements
  • Try measuring on a different surface with the included plastic shims
  • Hold the probe on the surface and allow it to take several measurements. If the second and subsequent measurements are consistent, you are not putting the probe onto the surface fast enough.
  • The substrate and/or coating surface is uneven, in which case inconsistent readings are to be expected. Take several measurements and average them to get a meaningful result.

Gage powers up but will not take any readings:

  • Substrate may not be metal. “F” probes measure coatings on ferrous metals such as steel and iron, and “N” probes measure over non-ferrous metals such as aluminum.
  • Protective cap must be removed from probe (if outfitted with one).
  • An extreme calibration adjustment might have been made.

Gage will not print to the Bluetooth wireless printer:

  • Ensure the gage has been paired for use with the printer and the Gage menu option

Connect > Bluetooth > Stream box is ticked.

  • Check printer batteries. Switch it off and then on again.
