The surface profile height (H
L
) measurement is immediately
displayed. The tape can now be removed. An hour glass will
display while 2D and 3D parameters are calculated.
Cleaning the probe opening (anvils)
The probe contains two measuring surfaces (anvils) and a camera
lens that can become contaminated with dust particles and residual
tape adhesive. It is therefore recommended to clean the probe
regularly with the included cleaning card and microfiber cloth. Cleaning
is essential prior to performing a probe zero (pg. 8) or a verification of
accuracy (below). It is best performed when the Gage is powered
down.
With the Gage powered-down, swipe the card through the opening a
few times while pressing both probe buttons. Then insert the included
microfiber cloth and gently wipe the surfaces of the anvils several
times by sliding the cloth back and forth with the probe buttons
pressed.
The cleaning card can also be used to clean the surfaces of analog
spring micrometers. Replacement cards and microfiber cloths are
available.
Cleaning the anvils is especially important when using the
PosiTector
RTR 3D
to measure 2D and 3D parameters or generating
SDF files.
NOTE:
Calibration & Verification of Accuracy
Calibration
Gage calibration is typically performed by the manufacturer or
accredited lab. All probes include a Certificate of 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. 8).
Verify accuracy of the digital micrometer measuring system
Place the
PosiTector
RTR Check Shim
into the probe opening. The
average of several measurements should be within the combined
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
