DeFelsko PosiTector 6000 Instruction Manual with Videos


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

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.

Magnetic & Eddy Current - Theory of Operation

The PosiTector 6000 probes calculate coating thickness measurements using either the magnetic principle (F probes - 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”.


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 https://www.defelsko.com/positector-6000

To disconnect a probe from a body, slide the plastic probe connector horizontally (in the direction of the arrow) away from the body. Reverse these steps to attach a different probe. It is not necessary to powerdown the Gage when switching probes.

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:

Integral - sensor protrudes from bottom of probe connector

Cabled - sensor is attached to the probe connector by a 1.2 meter (3 foot) cable.
(Extended cable length available.)

Available Positector 6000 Probes:

"Regular" - These constant-pressure, stainless steel probes are hermetically sealed to be totally waterproof - ideal for underwater use.

"Micro" - ideal for measuring small parts and hard-to-reach areas. Available in 0, 45 or 90 degree angles.

"Thick" - ideal for thick, protective coatings.

"Xtreme" - ideal for measuring rough and/or hot surfaces up to 250° C (500° F)

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.

line Calibration, Verification & Adjustmentline

PosiTector 6000 probes non-destructively measure 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 on known reference standards. A successful verification requires the Gage to read within the combined accuracy of the probe and the reference standards.

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 symboldisappears 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 symbolappears 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 Operationline

1-point Calibration Adjustment

Also known as an offset or correction value, there are 4 ways to perform this adjustment:

  1. 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".


  1. 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.

  1. Select Zero from the Cal Settings menu.
  2. 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.
  3. 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.
  1. 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.

1 Pt Adjust

  1. 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.

  1. Select 1 Pt Adjust from the Cal Settings menu.
  2. 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.
  3. 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) life the probe from the surface and adjust the reading down (-) or up (+) to the expected thickness and press.

2 Pt Adjust

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 fomr 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.

Cal Lock

When selected, theicon will appear and all calibration settings are "locked" to prevent further user adjustments. Uncheck to make further adjustments.

N Lock

(FN ferrous/non-ferrous combination probes only)

Select N Lock (Non-Ferrous?Lock) when operating regularly on non-ferrous substrates. Theicon 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.

line Calibration Memoryline

Cal Lock (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 theicon 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.

line Setup Menuline


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

  • All batches, stored measurements, images, and batch names are erased.
  • Theicon will appear on the display.
  • Menu settings are returned to the following:
Memory = OFF Cal Lock = OFF
High Res = OFF Bluetooth = OFF
Statistics Mode = OFF Display = None

Scan Mode = OFF  

Perform a more thorough Hard Reset as follows:

  1. Power down te Gage and wait 5 seconds.
  2. Simultaneously press and hold the (+) andcenter buttons until the Reset symbol appears.

This returns the Gage to a known, "out-of-box" condition and performs the same function as a menu Reset with the addition of:

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


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

Hi Res

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 ?m 0.0 999.9 ?m
1.0 ?m over 1000 ?m

NOTE: Gage accuracy is not affected.


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.


(Advanced models only)

By default, the PosiTector 6000 takes approximately 1 reading per second. Scan mode allows the user to take multiple readings in rapid succession (3 readings per second) without lifting the probe. Choose from 3 Scan modes:

  • Normal - continuously measures when placed on the surface.
  • Statistics - displays real-time scan statistics when placed on the surface. Average, max., min., and standard deviation are displayed.
  • Limited # Avg. - continuously measures until user-specified number of readings is reached, then displays the average for the scan.

When Memory is on, Scan measurement data is recorded. However, in Statistics and Limited # Avg. Scan modes, only the statistics and/or average is saved, not individual readings. Note that performing a scan may reduce the life of the probe and is recommended for smooth surfaces only. For additional information concerning Scan mode, visit https://defelsko.com/scan

Transfers selected  batches to the PosiTector App (useful when switching between devices).

The Send Batches option is visible in the Bluetooth Smart menu when the Gage is connected to a smart device running the PosiTector App.


(Advanced models only)

Allows individual readings to be sent to a computer, printer or compatible device as they are taken using Bluetooth wireless technology. See www.defelsko.com/bluetooth


The instrument and receiving device must be paired before stored or streamed datasets can be transmitted. For pairing instructions, see http://www.defelsko.com/bluetooth


Lists information about your current Bluetooth connection, including the currently paired device and MAC address..


When checked, the instrument will stream datasets to the paired Bluetooth Device as they are taken. Datasets can be streamed as they are taken to the optional Bluetooth printer or third-party computer software.

Powder Probes

Displays menu options that enable the PosiTector body to communicate with wireless PosiTector PC probes. See http://www.defelsko.com/pc

DeFelsko PosiTector 6000 Instruction Manual with Videos

WARNING: Ensure that stored measurements are backed up to a PC or PosiSoft.net.

The Gage will perform a Hard Reset after an update. All stored measurements will be erased from memory.

 Do Not unplug the Gage during the update operation.

line Temperatureline

Operating Range: +32° to +120°F (0 to +50°C)

The PosiTector 6000 compensates automatically for temperature. Allow a few minutes for the probe to reach ambient temperature before measuring.

Discard the first measurement taken in a notably different temperature condition. When measuring surfaces much hotter or colder than ambient, lift the probe at least 6 inches (15cm) and allow at least 1 second off the surface between measurements.

line Power Supply / Battery Indicator line

Power Source: 3 AAA alkaline, Lithium or optional Nickel-metal hydride (NiMH) rechargeable batteries. For best battery indicator results, ensure the appropriate Battery Type is selected in the Setup > Battery Type menu.

The battery indicator  displays a full bar with fresh alkaline or fully charged batteries installed. As the batteries weaken, the bar will be reduced. When the battery symbol is low  the Gage can still be used, but the batteries should be changed or recharged at the earliest opportunity. The Gage will turn off automatically when batteries are very low, preceded by a Low Battery Warning on the display.

To retain all user settings and stored memory readings, only replace the batteries after the instrument has powered-down. Battery performance decreases at low temperatures. 

Battery performance decreases at low temperatures

line Additional Accessories line

AC Power Cable Kit

An optional AC Power Cable Kit is available for continuous operation or battery charging through the PosiTector’s built-in USB?port (as shown on pg. 24). This kit supplies several alternate power solutions for your battery-operated PosiTector. They allow the gage to operate continuously without the need for batteries.

Use the cable alone to connect a PosiTector to your PC's built-in USB port that acts as a continuous power source. Or connect the cable to the included power adaptor which plugs into any AC wall electrical outlet, 110 or 220V.

A selection of electrical plugs is included which are capable of dealing with most country's outlets. The USB cable provided can also be used for Accessoring Stored Measurement Data.

USB Cable

A USB Cable is provided with every PosiTector.

Bluetooth Wireless Printer

PosiTector Advanced models can output to the optional battery powered Bluetooth Wireless Printer one of two ways:

  • Stream individual readings as they are taken.
  • Print stored batch readings and summaries.

Begin by entering the Connect > Bluetooth menu. Turn Bluetooth ON and "Pair" the PosiTector to the printer. See www.defelsko.com/bluetooth.

Streaming: In the Connect > Bluetooth menu, select the Stream tick box. All readings will now be simultaneously displayed on the LCD and sent to the printer.

Printing: In the Memory menu, select Print.

line Troubleshooting line

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

Probe takes a measurement even while held in the air:

  • The probe tip 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.
