VOLTCRAFT VC-590OLED Operating Instructions Manual page 48

For safety and approval reasons, it is not permitted to modify or alter the product in any way.
Consult an expert when in doubt about the operation, safety or connection of the multimeter.
Measuring instruments and accessories are not toys and must be kept out of the reach of chil-
dren!
For installations in industrial facilities, follow the accident prevention regulations for electrical
systems and equipment of the government safety organization or the corresponding authority
for your country.
In schools and training facilities and hobby and self-help workshops, the use of measuring de-
vices must be monitored by trained and responsible personnel.
Verify that the multimeter is set to the correct measuring range before each measurement.
Always remove the test leads from the measuring object before changing the measuring range.
The voltage between the multimeter's connection points and earth potential may not exceed
1000 V. DC/AC in CAT II or 600 V in CAT III.
Exercise extreme caution when handling voltages >33 V AC or >70 V DC! Even at such voltages
you can receive a life-threatening electric shock upon contact with electric wires.
To prevent electric shock, make sure not to touch the connections/measuring points to be meas-
ured directly or indirectly during measurement. During the measurement, you must not reach
beyond the textured grip area markings to touch the test probes and the meter.
Always check the multimeter and test leads for damage(s) before each measurement. Never
conduct measurements if the protective insulation is damaged (torn, missing, etc.). The included
test leads feature a wear indicator. If damaged, a second insulating layer of a different color
becomes visible. In this case, cease use of and replace the equipment immediately.
Do not use the multimeter immediately prior to, during or just after a thunderstorm (chance of
lightning! / high-energy overvoltages!). Please make sure that your hands, shoes, clothing, the
floor, switches, switching components, etc. are dry.
