the hardness tester does not correspond to the reference hardness test block
NOMINAL value within the error limits, it is necessary to calibrate the hardness
tester.
12.7. Special operation conditions
12.7.1. Increased dust content and humidity. Put the information processing unit
of hardness tester into a transparent plastic bag. Tighten it at the level of
connective cable a bit lower than the probe plug.
After the work under such conditions is finished, information processing unit shall
taken out of the plastic bag and air it.
12.7.2. Frost (<0°C). Information processing unit is the most sensitive to low
