2.1 General rules
In order to provide conditions for correct operation and the cor-
rectness of the obtained results, the following recommendations
must be observed:
before using the meter read carefully this manual,
the meter should be operated only by qualified persons that have
passed health and safety training,
be very careful when measuring voltages exceeding (as per IEC
61010-1:2010/AMD1:2016):
60 V DC,
30 V AC RMS,
42.4 V AC of peak value,
as they generate a potential risk of electric shock,
do not exceed the maximum limits of the input signal,
during the voltage measurements do not switch the device in the
current or resistance measuring mode and vice versa,
when changing ranges, always disconnect the test leads from the
tested circuit,
measuring probes should be kept in the space provided, restrict-
ed by a special barrier to avoid accidental contact with exposed
metal parts,
If during the measurement symbol OL appears on the screen, it
indicates that the measured value exceeds the measurement
range,
