5.3 Hardness/Strength testing

hardness testing is the only selection if the impact device is not D or DC type.
In main screen, Press key to change the hardness scale. The supported hardness
scale includes: HL, HV, HB, HRC, HS and HRB.
HL=Leeb
HV=Vickers
HB = Brinell
HRB=Rockwell B
HS=Shore
HRC=Rockwell C
Note ：
• This 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 first, then select hardness scale.
• Presetting hardness scale reverts to HL automatically after presetting
material is changed.

This function provides the user with the ability to view/delete a file/group
previously saved in memory.

and the mean value of the group. If there is no data in the memory, it will
display: <E04>, which means no memory data, and then return back.
2) Use the key and the key to select the desired file to view.
