Zero Calibration Adjustment
Measure your uncoated part. If the average of several readings is
not close to “0” (within the tolerance of the probe being used), a
zero adjustment should be made.
For many surfaces a single zero measurement should suffice.
To establish “0” on a rough or curved surface, a preferred method
is to take several readings on the uncoated part and average the
result.
Select Zero from the Cal Settings menu.1
Press X to select the number of readings to be used to2
obtain an average, typically 1 to 3 readings.
Repeatedly measure the uncoated part. The Gage will wait 23
seconds after placing the probe on the surface to allow the
user to correctly position the probe on the surface. After the
last reading the Gage will calculate a Zero which represents
the average of all the Zero readings taken.
The X icon will display.
Check that the Gage now reads within tolerance of Zero.4
