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 « 1 » blinks.
• Specification in AC : from 5 % of the range.
