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 sw
itch 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.
