Leeb Value Calibration
Please do calibration when use the device first time or interval for a
long time.
press ruturn button and On/Off button together (about 2 seconds)
to enter Leeb value calibration, the INSIZE logo will blink on top
left corner. Measure 5 times on the surface of standard test
block(you should do enter calibration mode again if get any value
which deviation is large).
2
Input the actual HLD value of the test block by use up and down
buttons, then press return button back to measurement mode.
3
Note: The distance between any two impact position should be
≥
3mm.
the distance between impact position and the edge of the sample
should be
≥
3mm.

Conversion Value Calibration
This calibration is applied to some workpiece you don’t know the
Leeb hardeness but only conversion hardness value like HB, HV, etc.
Note: Please do calibration with known hardness workpiece.
Press up arrow button to select the conversion scale, then Press
setup button then set measuring conditions by using up and down
