FAQ
1. Question: What is the working principle?
It is according to Leeb Hardness principle – the impact rebound method: according to the rebound speed and impact speed to calculate the hardness value.
2. Question: How to use the tester?
Answer: 1) The one of the most important step is loading,
 Push down the loading sheath to lock the impact body; for DC type impact device, the loading bar can be attracted on testing surface and insert DC type impact device into loading bar until the stop position, then loading has been finished.
 Press tightly the support ring of impact device on the surface of test sample, the direction of impact should be vertical with testing surface.

2) Test
Press down the release button on the top of the impact device to make a test. At this point, the test sample, impact device and the operator are all required to be stable; and the force direction should comply with the axis of the impact device. 

3)  Average value
The instrument will calculate the average value after 5 times test(same area, but not same point), and show the average value on display.
