Measurement Procedure
1.
Long press the On/Off button to turn the gauge on.
2.
Check the specimen and select a suitable calibration method. Calibrate
accordingly and the latest calibration will be stored and applied as a rule.
3.
Set upper or lower limit when necessary.
4.
Set statistics, storage and adjust other settings when necessary.
5.
Start measurement. Note that the probe should be put perpendicular to the
surface to be measured to minimize measurement error.
6.
Turn off the gauge after measurement by long press the On/Off button.

Calibration
1. Types of calibration
1)
Zero calibration: single point, use the zero plate directly.
2)
2 point calibration, smooth: suitable for coatings on smooth surface.
3)
2 point calibration, rough, method 1: recommended for sand- or shot-
blasted surfaces with roughness of less than 55-65 µm. Calibration
should be done directly on the blasted surface without coating.
4)
2 point calibration, rough, method 2: recommended for sand- or shot-
blasted surfaces with roughness of more than 55-65 µm. Calibration
should be done directly on the blasted surface without coating.
5)
Factory calibration, can be reset by restoring factory setting.
Note: As to the selection of standard film, one that is slightly thicker than the
coating to be measured should be used for calibration. For example, for a
coating of about 80 µm, a standard film of 125 µm should be applied for
calibration.
