Leeb hardness: provides quality shocks under the elastic to a certain speed of impact specimen surface and spring back, with an impact on 1mm from the sample surface of rebound speed speed ratio calculation of hardness and impact value.
Calculated as: HL=1000xVB/VA

In the formula: HL--hardness value
VB--impact of rebound speed
VA--impact body impact speed

Based on hardness measurement, can be used for metallic materials-hardness and impact strength test adapter 6 types of devices; Automatically identifies impact devices types, replacement without recalibration
Automatically detect impact device state (connect, disconnect, failure status)
Automatic identification of the impact direction (except G-shock device), 360 ° Omni-directional free measurement

Methods of measurement
Measurement before the first use of hardness test block for random testing of instruments, the indication error and repetition should not exceed specification requirements of table 2.
Start
Impact impact device socket of the device plugged into the right side of the instrument. Press "on/off" button, at this time the power is switched on, the instrument enters the measuring State. Loading
Push the load lock down the impact body; DC impact device, can be loaded on the test surface, insert the DC impact device loaded, until the stop position at this time is finished loading.
Positioning
Impact device supporting ring according to the selected measuring fast on the surface, the impact should be perpendicular to the test surface.
Measurement
Press the release button at the top of percussive machine, were measured. Request samples, impact device, the operator is stable, and force should be directed through the impact device axis.
General conduct five tests for each portion of the sample. Data should not exceed the average of 15HL.
Between two arbitrary indentation distance or a centre of indentation from the specimen edge distance should conform to the specifications in table 3. For certain materials, Leeb hardness value to be accurately converted into other hardness value comparison test must be done to get the corresponding score. By: standards by Leeb hardness tester and respectively in the hardness test on the same sample, for each a hardness value in more evenly distributed around the conversion of hardness indentation is needed in the determination of hardness values, average hardness and hardness on the Richter scale respectively as the corresponding value, hardness comparison curves. Contrast curves should include at least three groups correspond to the data.
Read the measuring value
More effective tests for average hardness testing data.
Leeb hardness hardness values are shown before the symbol HL, HL behind impact device types are shown. Such as 780HLD d impact device for the determination of hardness value of 780. For Leeb hardness conversion of hardness, hardness of Leeb hardness before the symbol, together with the corresponding symbol. For example 420HVHLD indicates that d-type Leeb hardness conversion impact device for the determination of hardness values was 420.
Note: the different types of impact device HL measured values, for example, 780HLD ≠ 780HLC.

Impact devices maintenance
Impact device using 1000~2000 after time, use a nylon brush clearing catheters that impact devices and the impact body. While cleaning the duct support rings in first rotation, and then remove the impact body, nylon brush with counterclockwise into the tube, pull out after, and repeat 5 times, then the shock body and supporting ring put on
After use, impact should be released
Impact device must not be used within a variety of lubricants storage should stay away from vibrations, strong magnetic fields, corrosion, damp, dust, should be stored at room temperature
