2.1.1 Duramin-40safety precautions
Read carefully before use
1. Ignoring this information and mishandling of the equipment can lead to severe bodily injuries
and material damage.
2. The operator must read the safety precautions and Instruction Manual, as well as relevant
sections of the manuals for any connected equipment and accessories.
3. The machine must be installed in compliance with local safety regulations. All functions on the
machine and any connected equipment must be in working order.
4. The machine must be placed on a safe and stable table with an adequate working height.
Failure to do so can affect how the machine works and cause the equipment to drop from the
table and/or cause accidents and injuries.
5. All safety functions must be intact and in working order. If they are not, they must be replaced
or repaired before the machine can be used.
6. Make sure that the actual electrical power supply voltage corresponds to the voltage stated on
the type plate of the machine. Failure to do so can result in the machine catching fire.
7. Do not twist or damage the power cables. Damaged power cables can cause fire and/or
electric shock.
8. Never block the ventilation. The machine can overheat and it can cause fire.
9. Never try to modify this equipment, as doing so can result in fire and/or electric shock.
10. Never try to disassemble this equipment. Doing so can result in electric shock.
11. Never open any panel on the machine while it is turned on. Doing so can result in electric
shock.
12. Do not allow the machine to come into contact with any liquid. The equipment can catch fire if
water or any liquid gets inside it. If water or any other liquid gets inside the machine, turn off the
power, disconnect the power supply and call technical service.
13. Do not connect or disconnect power with wet hands. Doing so can result in electric shock.
14. If you observe malfunctions or hear unusual noises, stop the machine and call technical
service.
15. If two persons work together, make sure they communicate clearly to avoid injuries.
16. Disconnect the machine from the power supply before cleaning it. Failure to do so can result in
electric shock.
17. Struers equipment must only be used in connection with and as described in the instruction
manual supplied with the equipment.

3 Getting started
3.1 Device description
Duramin-40 offers a technology base for manual, semi-automatic or fully automated testing of Micro
and Macro Vickers, Knoop or Brinell assignments.
The specimen is placed on the anvil/XY-stage, and the desired testing pattern is set up using the
testing software.
When the test is started, the indenter will move down and indent the specimen with the selected
force.
Following the indentation, the result is obtained by an optical measurement of the indent.
The results can be stored or exported using several formats.
