6.5 Software calibration

The tester and impact device must be calibrated with a standard Leeb hardness test block prior to the first use, or reusing after a long term idle.

Press  key as well as  key at the same time to enter the interface of software calibration. The impact times is set to 5. And the impact direction should be vertically down on the Leeb hardness test block.

Average value will be showed after measuring. Press  or   key to input nominal value. Press  key to finish calibration and back to the main unit,press  key to cancel;

Note: calibration range is ±15HL.
