  • Page 18 The preparation for workpiece surface should comply with the relevant requirements specified in table During the preparation for sample, the affect to surface hardness of sample caused by overheating, cold processing and etc. should be avoided as far as possible. If the surface to be tested is too rough, measuring error will appear.
  • Page 19 —— The workpiece with medium weight must be placed on flat and solid plane, and it must be placed stably without any shaking. Enough thickness of workpiece is necessary, and the min. thickness should comply with the specification in table 3. As for test piece with hardened surface layer, the depth of hardened layer should comply with table 3.

Impact direction: current impact direction. Average value indicator: average value will be displayed when impact times setting has been achieved. Hardness scale: the hardness scale of current measuring value.

    6.2.2 Testing procedures Testing can be carried out under this interface status, and the current measured value will be displayed whenever one measurement is finished. The counting of impact times will add 1 per measurement is performed. It will display the message "Out of range" provided that the value exceeds tolerance limit; If the impact times which has been set is achieved, the average value will be displayed after 2 seconds waiting.
