“Zero-point calibration”

Switch on the instrument. Choose the mode Single measurement: Menu “Options” “Measure Mode” “Single mode”. Place

the probe on uncoated sample.

See indication on the display. Place the probe 10 cm away from the surface.

Press and hold button “Zero” for 1,5 sec. You will see indication on the display 0.0 um. The calibration is nished. Repeat

this procedure several times If necessary. Make a new zero-point starting a measurement.

“One-point calibration”

This method is recommended for high precision measurements, measurements on small parts and on hardened and

low-alloy steel.

Calibration: Menu “Options” “Calibration” “Enable”.

The indication “Cal n (or 1~2 Zero n (or y) will be displayed.

n - no point of calibration and zero-point calibration.

y - zero-point calibration.

Cal 1~2’ - one-point calibration or two-point calibration.

1. “Zero-point calibration”

Place the probe on uncoated sample.

Make zero-point calibration.

Measure foil thickness. Remove probe from the surface. Press buttons ▲/▼ to adjust required foil thickness. Repeat the

measurement of the coating thickness. To conrm press ‘ZERO’.

To disable calibration: Menu • «Options» «Calibration» «Disable».

*The selection of the foil: the results of the following measurements must be between zero and the value of the foil.
