• Do not measure voltages above 300 V! If you will be measuring the current, check the multime-
ter's fuse and turn off the power supply to the circuit before you connect the multimeter. Before
measuring make sure the circular switch for the measuring range is in the correct position. Under
no circumstances should you make any changes in the measuring range (by moving the circular
switch for measuring programs) when measuring! It could lead to device damage. When you are
measuring, connect the black conductor (probe) first and then the red conductor (probe). When
disconnecting the testing conductors, disconnect the red one first.
• If you find that the meter is registering abnormal measurements, 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 the one indicated 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 electrical values you know.
• 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.
• When changing parts of the multimeter (e.g. the battery or fuse) use spare parts of the same type
and specifications. Change parts only when the multimeter is disconnected and turned off. Do
not change the 10 A/300 V fuse by yourself, please contact a service centre. Disconnect the testing
conductors from the tested circuit before opening the rear casing of the device.
• Do not alter or otherwise interfere with the internal circuitry of the multimeter!
• Please be careful when measuring voltages higher than 30 V AC rms, 42 V peak or 60 V DC. There
is a risk of injury resulting from electric shock!
• When using measuring tips, make sure you are holding them behind the finger barriers.
• Do not perform measurements if the multimeter's casing is removed or loose.
• Change the batteries when an icon of a discharged battery appears “ ”. In case you do not do so,
the following measurements may not be precise. Incorrect measurements may then result in injuries
by electric current! Use only alkaline batteries, do not use re-chargeable batteries.
Maintenance Instructions
Warning
Do not attempt to repair or modify the multimeter in any way if you are not qualified to do so or do
not have access to the necessary calibration equipment. Make sure that water does not get into the
multimeter – you could prevent injury by electric current!
• Disconnect the measuring tips from the tested circuit before opening the casing of the multimeter.
• Regularly clean the body of the multimeter with a moist cloth and a mild detergent. Perform cleaning
only when the multimeter is disconnected and turned off.
• Do not use solvents or abrasive agents for cleaning!
• If you haven't been using the multimeter for a longer period of time, turn it off and remove the batteries.
• Do not store the multimeter in places with high humidity and temperature or in environments
with strong magnetic fields!
Changing batteries
When the " " symbol appears on the display, this means the battery is low and must be immediately
changed.
To replace the batteries, unfasten the screw at the rear of the casing and remove the casing. Change
the discharged battery for a new one of the same type (9 V, 6F22 type or equivalent) and adhere to the
correct polarity of the placed battery. Replace the rear casing.
