6 ADJUSTING GAUGE CALIBRATION

Before taking measurements, always adjust the calibration of your gauge by zeroing your gauge on
uncoated steel or aluminium sample having the same substrate thickness and a similar smooth surface
finish as the item to be measured.
1. Select MENU/ZERO
2. When indicated by the display, place the probe on the uncoated substrate.
The display will show 0 µm (or 0.0 mil) and is immediately ready to use.
You may wish to test the calibration using the foils supplied with your gauge.
If a sample of uncoated substrate is not available, use the factory calibration zero:
Select MENU/RESET/FACTORY CAL/YES.

7 PROBES

The probe is a consumable item and will eventually wear. Probe life will depend on the number of
measurements taken and how abrasive the coating is. Probe life can be prolonged by careful positioning of
the probe on the surface. If the probe becomes worn or damaged, return your gauge to Elcometer for probe
replacement and re-programming.
