of hardness scales HRB, HRC, HV, HB, HS, HL and three types of strength values 
immediately.
Seven impact devices are available for special application. Automatically identify the type 
of impact devices. 
Large capacity memory could store **0 groups (Relative to average times*2^1 ) information 
including single measured value, mean value, testing data, impact direction, impact times,
material and hardness scale etc. 
Upper and lower limit can be preset. It will alarm automatically when the result value exceeding
the limit. 
Battery information indicates the rest capacity of the battery and the charge status.
User calibration function.
