3 USING THE MULTIMETER
3.1 Preliminary notes
 If the battery is weak, the display shows the message “ ”, the battery should,
therefore, be replaced.
 Check that the probes are in good condition. If they are damaged, replace them.
 The function selector switch must be positioned on the appropriate scale before use.
 Do not perform measurements of voltage or current that exceed the maximum capacity
of the instrument.
 Properly insert the battery in its compartment.
 Always select a capacity which is greater than the value of current or voltage to be
measured.
 Make sure the probes are properly connected to the circuit.
 Check that the rear cover of the instrument is always closed.
 Remove the battery from the instrument when not in use for a long time.
 Remember to turn off the instrument after use.
 Do not attempt to measure the resistors inserted into live circuits or before discharging
any internal capacity of the circuit.
