    Zeroing Dial Indicator

    • The vertical position of the Contact Point, needs to be Zeroed with respect to the Knife Edge of the Blade.
    • Zeroing can be accomplished in two ways; by adjusting the Height of the Dial Indicator in the Blade; or by Rotating the outer Bezel Scale while pressing on the Plunger onto a flat surface.

    Scale Zeroing
    • To quickly check the Zero Point of the Dial indicator, place the Blade on a representative smooth surface.
    • Gently press the Plunger, until the contact point touches the surface.
    • While the contact point is on the surface, loosen the Bezel Lock, and rotate the Bezel Scale until it reads '0' with respect to the pointer.

    Height Zeroing
    • Loosen the Fastener(s) holding the Dial Indicator in place.
    • Hold the Blade firmly on a Flat Surface, and gently press the body of the Dial Indicator down until the contact point touches the flat surface.
    • Carefully re-tighten the Clamp Fastener(s) or the Set Screw.
    • Any fine zeroing can be done by rotating Bezel Scale on the Indicator.
    • Height Zeroing should be done, whenever the unit is put into to use.

    Zeroing a Digital Indicator
    • Digital Indicators can be Height Zeroed or Positioned in the same way as a Mechanical Dial Indicator.
    • To Zero the Digital Indicator simply press the Zero Button when the Contact Point is on a reference point. If the Digital Indicator is Height Zeroed, press Zero when the Plunger is fully retracted.
    • To select Metric or Imperial Measurement, simply press the mm/in Button.Whennot in use, press the On/Off Button to turn the Indicator off.

    Indicator Positioning
    • The position (or rotation) of the Dial indicator can be changed by simply loosening the Clamp Fasteners or Set Screw, and rotate the Dial Indicator about the Blade.
    • After the Dial Indicator is rotated, the unit should be Dial Zeroed.
