Prepare the Gage
With the Gage powered-down, clean the measurement surfaces
using the included cleaning card. Swipe the card through the
probe opening a few times while firmly pressing both probe
buttons to remove dust particles and residual tape adhesive.
Power-up the Gage by pressing the center navigation button.
An image appears indicating that the probe requires zeroing.
Simultaneously press and hold both probe buttons
firmly until the Gage beeps and the arrows point
outward. Do not place anything in the
measurement opening during this procedure.
Measure the included check shim to verify accuracy (pg. 5).
Ensure the correct grade of replica tape, C or XC, is displayed in
the upper left corner of the gage display (pg. 6).
Measure
Insert the burnished replica tape into the
probe opening as far as it will go. Ensure
the tape is properly positioned so that the
burnished region is centered within the
opening with the adhesive (sticky) side down.
To position the tape, align the two dots (printed on replica tape)
with arrows on both sides of the measurement opening.
If you are using older tape that does not have the printed dots,
simply align by centering the tape within the measurement opening.
During measurement, a constant anvil pressure is applied to the
replica tape regardless of how hard the two buttons are pressed.
The Gage automatically subtracts the 50.8 µm (2 mils) of
incompressible polyester film. No further adjustments are required.
1. Ensure tape is properly positioned.
2. Firmly press both probe buttons simultaneously and hold until
the Gage beeps and the surface profile height (H)
measurement is displayed. The tape can now be safely
removed.
