– if the value of the measured parameter is not known beforehand, set the
maximum range;
– do not touch unused jacks when the meter is connected to a measured
circuit;
– do not use the multimeter when the back cover is not closed or the casing
is loosely closed;
– connect the test probe after connecting the basic one, disconnect them in
reverse order;
– do not measure the resistance in the circuit under tension;
– to avoid the risk of electric shock due to incorrect readings, replace the
battery immediately when the " " icon appears;
– always be careful when working with voltages over 42 V, when making
measurements keep your fingers behind the barrier edge of probes.
Measures to protect the multimeter against improper use
To avoid the damage to the multimeter, follow these guidelines:
– disconnect the power and discharge the high-voltage capacitors when
measuring the electrical resistance, checking the circuits integrity, diodes;
– use the jacks, functions and ranges of measurements in accordance with
the regulations;
– before turning the range switch to change functions and ranges of
measurement, disconnect the measuring probes from the tested circuit;
– when working with television receivers, monitors and pulsed power sources
remember that in some points of their electrical circuits there is a high voltage
pulse amplitude that can damage the multimeter;
– protect the multimeter from direct sunlight, high temperature and humidity.
