The zero point setting should be checked and, if necessary, corrected before
each measurement.
Zero calibration
Checking/Calibrating the zero point
1
Turn the device off/on
2
Set the measuring mode:
Menu > Options > Measure mode > Single mode
Exit the menu: press key 1 twice
3
Perform measurement (see item 12):
measurement on uncoated material
(original material or reference material)
Value within tolerance
(see technical data):
check complete; no calibration necessary
Value outside tolerance
(see technical data):
Calibration required: press and hold the ZERO key (3);
repeat steps 1-3 to check
One-point calibration calibrates a coating thickness as close
to the expected measured value as possible.

in order to increase the measuring accuracy. The expected
measured value should be as close as possible to the mid-
point between the calibration points (cal 1 and cal 2).
