substrate. Gage automatically
recognizes the substrate.
Ferrous: measures on steel only.
The letter “F” is always displayed.
Operation: Press either button to power-up.
Place flat on surface. Hold steady. When
measurement is obtained, new reading flashes.
Lift gage or leave on the surface for repeated
measurements.
Menu: Press both buttons simultaneously
to access the gage menu. Navigate the menu

Zero Calibration Adjustment: Measure the
uncoated part. Zeroing provides the best
coating thickness accuracy.
1 Point Calibration Adjustment: Also
known as ‘Offset’ or ‘Correction Value.’
Measure a known thickness. Adjust the reading
up or down using the gage buttons until
expected thickness is displayed. Press
to accept.
