11 Maintenance and inspection
Periodically checks of the device should be executed with standard hardness
test blocks. The thickness of the test block is very important, due to the
measuring method. It should be no less than 16 mm. Test blocks of lesser
thickness (e.g. 6mm) aren't suitable. DKD-certified test blocks of 16 mm
thickness are available at the manufacturer of the device.
Depending on the frequency of use, a check / maintenance of the probes
should be performed at intervals of 1 to 2 years.
