5-2 Issue 03, 04/2005 Krautkramer DynaPOCKET
5.1 Checking the function
Please check the functioning of the impact device and
hardness tester by measuring the HL hardness value
on the hardness reference block before using the in-
strument for the first time, and afterwards from time to
time (always after 1,000 impacts at the latest).
– Take the hardness reference block from the case
and place it on a solid base support.
– Carry out 3 to 5 measurements on the hardness
reference block. Ensure that the spacing between
the measurement locations is a minimum of 3 mm.
– Read the average and compare it with the reference
value of the hardness reference block.
In the case of larger deviations, the tungsten-carbide
ball functioning as a spherical test tip must be re-
placed.

5.2 Troubleshooting
When turned on, the DynaPOCKET carries out
an automatic system self-test. In addition, the
DynaPOCKET’s self-monitoring function is active
during the operation.
If system errors or operating errors should occur, they
are displayed by a corresponding error code (e.g. E 0.1).
