SAFETY INSTRUCTIONS:
• Use sockets, functions and measuring ranges as described herein.
• Do not use the multimeter if its housing is damaged. Pay particular attention to the
connection sockets.
• Use original probes from this model of the multimeter. Do not use defective probes.
Check the insulation of the probes regularly. When measuring, keep your ngers behind
the barrier edge of the probes.
• Do not use the device with the back lid open or the housing loosely closed.
• Never exceed the overload capacity values of the device specied for each measuring
range.
• Do not touch any unused sockets when the device is connected to the measured circuit.
• If you do not know the measured value order before measuring, set the range switch to
the maximum value.
• Before changing the position of the range switch, disconnect the probes from the circuit
to be measured.
• When measuring in TV sets and static power supplies, be aware that high voltage pulses
may be present at the measured points, which can damage the device.
• Disconnect power and discharge high voltage capacitors when measuring electrical
resistance, testing circuit continuity and diodes.
• Before installing the transistor for testing, make sure that the probes are not connected
to electrical circuits.
• Never measure resistance in a closed circuit.
• Replace the battery as soon as the symbol appears
