3. FUNCTION DESCRIPTION

3.1

AC or DC voltages

• Connect the leads to the multimeter (COM and V terminals) and
connect it in parallel to the circuit to be tested.
• Position the selector switch on the voltmeter function " V or mV ".
• Automatic range selection : read the measured value.
• Memorise it, if necessary, by pressing the " MEM " key.
• Overload : the beep sounds and " OL. " blinks.
• Specification in AC : from 5 % of the range.
