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.
The probe contains two measuring surfaces that can become
contaminated with dust particles and residual tape adhesive.
It is therefore a good idea to clean the probe regularly with the
included cleaning card. Cleaning is essential prior to performing
a probe
Zero
(pg. 6) or a verification of accuracy (below).
Cleaning is best performed when the Gage is powered off.
With the Gage powered-down, swipe the card through the probe
opening a few times while firmly pressing both probe buttons.
The card can also be used to clean the surfaces of analog spring
micrometers. Replacement cards are available.

Verification of Accuracy
Calibration
Gage calibration is typically performed by the manufacturer or
accredited lab. All
PosiTector
RTR H
probes include a
Certificate of Calibration.
Calibration & Verification of Accuracy
Ensure that the probe has been cleaned with the included cleaning
card (above) and that the probe has been zeroed (pg. 6).
Place the

Check Shim
into the probe opening.
The average of several measurements should be within the com-
bined tolerance of both the Gage and the shim. If not, the Gage
may need to be returned for service.
The check shim is specifically intended for all
PosiTector
RTR
probes. The Gage is designed to measure burnished replica tape
within a limited measuring range and automatically subtracts 50.8
µm (2 mils) from height measurements to account for the incom-
pressible polyester film. Therefore plastic shims intended for other
