within a limited measuring range and automatically subtracts 50.8
µm (2 mils) from height measurements to account for the
incompressible polyester film. Therefore plastic shims intended for
other instruments such as coating thickness gages will not be
measured properly.
Verify the optical measuring system
Place the Peak Density Check Tape into the probe opening. The peak
density (Spd) result should be within tolerance specified on the tape.
If not, the Gage may need to be returned to your dealer for service.
NOTE:
Ignore the peak height (H) result when using the Peak
Density Check Tape.
Zero
The probe should be zeroed regularly to ensure best accuracy. The
user will be prompted to zero the probe every time the Gage is
powered-up. The Zero menu item allows the procedure to be
performed at more regular intervals. It is particularly useful during
long measurement sessions.
Important: Clean the probe with the included cleaning card (pg. 7)
before performing a probe zero.
1. Select Zero from the Cal Settings menu
2. 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.
SHORTCUT:
firmly until the Gage beeps and displays "0". This can be performed
from the main measurement screen without having to access the menu.
Tape Grade
Selects a replica tape grade. Required when Linearize mode (H
C - Coarse
NOTE:
Coarse Minus and X-Coarse Plus grades are not
supported in Linearize mode since the only function of these two
grades is to improve upon the accuracy of C tape at its low end
and XC tape at its high end, something the PosiTector RTR 3D will
automatically do when measuring H
