NOTE”
1.The hardness scale will return to HL after changing the material setting.
2.Please choose the material before choosing hardness scale.
5.3 Hardness/Strength testing
Press
key to switch between hardness testing and strength testing (бb) .
Note: Only D and DC type of impact device has the function of strength testing. So hardness
testing is the only selection if the impact device is not D or DC type.
In hardness testing, Press
S

E
key to change the hardness scale. The supported hardness scale
includes: HL, HV, HB, HRC, HS, HRB and HRA.
Note
：
Here only displays the valid hardness scale for the present selected impact device and
material. It would not display the hardness scale which is not valid.
Please select material firstly, then select hardness scale.
Presetting hardness scale recovers to HL automatically after presetting material is changed.
5.4 Impact Direction Setting
Press the
key to move to the impact direction that you will preset.
5.5 Average Times Setting
You could modify average times within the range of 1 to 32 as following:
1) Press
key in testing state. The impact times item will begin to flash.
2) Press
or
key to set the average times to the number you want.
3) Press
key finally to exit from the operation.
5.6 Data logging
At most one hundred files (F00-F99, one group as one file) can be stored inside the gauge. By simply
