4.3 PERFORMING MEASUREMENTS
4.3.1 DC/AC Voltage measurement
➢ Maximum input is 1000VDC or 1000VACrms. Do not take any voltage
measurement exceeding this limit in order not to risk electrical shock or
damaging the instrument
➢ Do not use the instrument to measure voltages in circuits that could be
damaged by instrument's low input impedance (approx. 6k)
1. Insert the red test lead plug into V- jack and the black test lead plug into COM jack
2. Connect the two long ends of test leads to the desired circuit (see Fig. 3) then reading
will be displayed. The instrument selects automatically AC or DC notation depending
on input voltage type
For Phase to Ground voltage measurement after a RCD device, to avoid
unexpected trips-out, preliminarly connect the test leads between Phase and
Neutral cables at least 5s, then perform the Phase to Ground measurement
3. "OL" message is shown at display if the voltage under test is over the maximum value
that the instrument is able to measure.
4. The "-" symbol at display means that the DC voltage have an opposite sign respect the
connection of Fig. 3
5. For HOLD function please refer to § 4.2.1
