4.3. FUNCTIONS OF ROTARY SWITCH DESCRIPTION
4.3.1. AC Voltage measurement
CAUTION
Maximum input for AC Voltage measurements is 1000Vrms. Do not take
any voltage measurement exceeding this limit in order not to risk electrical
shock or damaging the tester
Fig. 3: Taking AC voltage measurements
1. Rotate the switch on
position
2. Insert the red test lead plug into V jack and the black test lead plug into COM jack
(Fig. 3)
3. Connect the two long ends of test leads to the desired circuit, then reading will be
displayed
4. When “O.L." symbol is displayed, the result exceeds the maximum value that the
instrument is capable of measuring
5. With meter switched on and rotary switch in each position move the integrated sensor
close to an AC source. The red LED turns on for detected voltage > 100V
6. For HOLD, MAX/MIN and REL features please refer to § 4.2
CAUTION
 Due to the high input impedance is possible that the meter performs the
zero of the display taking longer
 The possible blinking values shown at display with open input terminals
are not a problem of the meter and these values will not be added to
the measured value
