Do not touch exposed metal parts such as test lead ends, sockets, fixing objects,
circuits etc.
Avoid doing that if you notice anomalous conditions such as breakages, deformations,
fractures, leakages of battery liquid, blind display etc.
Be particularly careful when measuring voltages exceeding 20V to avoid risks of
electrical shocks.
The following symbols are used:
CAUTION - refer to the instruction manual - an improper use may damage the
instrument or its components
