Measure the diameter of the indention using the microscope in 2 directions perpendicular to each
other. Remember the values and enter as shown below, marked as d1 and d2 on the digital
display of the machine
Press “ ”or“ ” key to move cursor to “3” HBW Calculator in figure 5.2.1, then press “
” key
to confirm. Figure5.3.5 appears. Press “ ”or“ ”key to input the two diameters, d1 and d2. And

Remove the test force completely, and switch off the power supply. Remove power cord when machine will not
be in use for an extended period of time.
6 Maintenance
6.1
When the hardness tester is to be repositioned in another area of your facility, the indenter must be
removed. If it is to be transported for a long distance, the original packaging must be restored.
6.2
When performing any adjustments and examining in the machine, the power supply must be turned
off.
6.3
When installing or removing the indenter, the mounting surface should be clean and dry. The indenter
should be removed carefully and placed back in its supplied case if not being used for an extended period of
time.
6.4
The surface of anvil and standard hardness blocks should be clean without contamination, scratches or
rust. When storing anvils or test blocks, they should be lightly coated with oil to prevent rusting.
6.5
Dustproof and corrosive medium prevention should be considered in daily operating environment. Rust
prevention measures should be adopted in high humidity area.
6.6
The leadscrew of the anvil should be lubricated periodically. Apply a few drops of light machine oil,
then run the leadscrew up and down a few times to distribute the oil.
6.7
Please don’t disassemble or adjust any fixed parts. This will void your warranty. This should be done
by a professional service person familiar with the machine.
