capacitors. Use a function appropriate for the given measure-
ment. Before changing the range (or switching functions) dis-
connect the conductors from the circuit that is being measured.
• Make sure the device is undamaged before you begin using the
multimeter. If you find obvious signs of damage on the body of
the device, do not make any measurements! Check that the
surface of the multimeter does not have scratches and that the
side joints are not coming apart.
• Also check the insulation on the measuring probes. Damaged
insulation may result in injury by electric current. Do not use
damaged measuring probes!
• Do not measure voltages above 1 000 V! If you intend to measure
current, check the multimeter‘s fuse and turn off the power
supply to the circuit before you connect the multimeter. Before
measuring, make sure the circular switch for setting measuring
range is in the correct position. Under no circumstances should
you make any changes to the measuring range (by moving the
circular switch for changing measuring programmes) while
measuring! Doing so could damage the device. When you are
measuring, first connect the black conductor (probe) and then
the red conductor (probe). When disconnecting the testing
conductors, disconnect the red one first.
• If you find that the multimeter is making abnormal measure-
ments, stop using it. The fuse may be damaged. If you are unsure
of the cause of the defect, contact a service centre.
• Do not measure voltages higher than listed on the front panel
of the multimeter. Risk of injury by electric current or damage
to the multimeter!
• Check that the multimeter is working properly before use. Test
on a circuit with known electrical values.
• Before you connect the multimeter to a circuit you intend to
measure, turn off the power to the circuit.
• Do not use or store the multimeter in environments with high
temperature, dust or humidity. It is also not recommended to
use the device in environments with potentially strong magnetic
fields or risk of explosion or fire.
