that there was a second layer of paint and lacquer applied to this
given part.
However, if the measurement is more than 2 times the average
value, it means that there is also a layer of putty filler underneath.
The higher is the thickness, the less quality repair job was
performed.
Calibration of zero deviation
The device zero reading can be calibrated for various base metal.
This is required when, for example, the device reads coating
thickness over zero for uncoated, bare metal. Calibration of zero
deviation will solve this issue.
To calibrate zero reading, do the measurement on the uncoated,
bare metal base. When the result is displayed, press and hold
“UNIT” button for 2 seconds. Once the screen displays “CAL”, the
calibration of zero deviation is complete.
Calibration reset
This function will reset the zero calibration and 2-point calibration
to factory default values.
To perform calibration reset in measurement ready state (screen
displaying “----”) press and hold “UNIT” button for 2 seconds.
Once the screen displays “-CL-” and you hear a beep, the
calibration reset is complete.
