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. 5)
before performing a probe zero.
1. Select Zero from the Cal Settings menu
2. Simultaneously press and hold both probe buttons firmly until

performed from the main measurement screen without having to

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 will
automatically do when measuring H
OFF, the PosiTector RTR will measure all grades of replica tape
just like a conventional spring micrometer.
