heavy dust.
1.6 Safety Instructions
zThe instrument can only work with the specially designed battery pack and power adapter
(charger) supplied by Mitech Co. LTD. Working with others may result in damage of the
instrument, battery leakage, fire or even explosion.
zDo not cast the battery pack into fire and do not short circuit, disassemble or heat the battery pack,
otherwise battery leakage, fire or even explosion may occur.
Do not open the cover of the paper compartment or come into contact with the heating head of the
printer by hand or any part of your body to avoid burns due to high temperature when the printer is
printing.

Press key to store present group of measured value into memory. This operation is only valid after
displaying the mean value.
zPress key and could display single measured value.
zPress key could switch on of off the background light of LCD.
zPress key to set the impact direction.
zPress key to change the impact times in one group. The impact times item will flash when first
pressing the key, and then the impact times value will plus or minus when pressing the or
key. Press key finally to exit from changing the impact times process.
zPress SCAL E key to change the hardness scale.
zPress key to change the material. Presetting hardness scale recovers to HL automatically after
material presetting changed.
zPress key to switch between hardness test and strength test. Only D and DC type of impact
device has the function of strength testing. So hardness testing is the only selection if the impact
device is not D or DC type.

zPress key to print out the measured values after measurement.
zPress FEED key to manually feed the paper.
2.4 Leeb Hardness Testing Principle
The basic principle is to use an impact body of certain weight impacts against the testing surface
under certain test force, then measure the impacting velocity and the rebounding velocity of the impact
body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
HL=1000×VB/ VA
Where, HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
3 Preparation
3.1 Instrument Preparation and Inspection
Verification of the instrument is by using standard test block. The error and repeatability of
displayed value should be within the regulation of Appendix table 2. The instrument and impact device
must be calibrated using a standard hardness block before use as the first time, or having not been used
for a long time, or having reset the instrument system.
Press key, meanwhile pressing down the key to power on the system. Then the user
calibration screen shows as left below.
Test for 5 points on the standard hardness block.
It would display the average measured value
after measuring 5 times. Press key to
change to its nominal value.
Press key to confirm the calibration finally. Or
press the key to cancel the calibration.
Range of adjustment: ±30HL.
The measurement parameters, including the material setting, the hardness scale and the impact
direction can’t be changed during calibration.
3.2 Impact
Device
Selection
Refer
to Appendix
Table 1 and Table 3 for selection of impact device.
Note：Use a calibrated hardness tester, test the standard test block
downward vertically for 5 times, the arithmetical average value compare with
the value of standard test block. If this value exceeds the standard value, could
use the function of user calibration to adjust.
