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,
