7.6. USING THE METER IN A SINGLE PHASE SYSTEM
CAUTION

The maximum voltage between inputs D1, D2, A1, A2 and A3 is 1000V /
CAT IV 600V to earth. Do not measure voltages exceeding the limits
indicated in this manual. If these voltage limit values are exceeded, the
user may be exposed to electrical shocks and the instrument could get
damaged

If possible, before connecting the meter to the electrical equipment to be
tested turn the power supply off
Fig. 165: Meter connection in a Single phase system
1. Check and modify the basic settings of meter if necessary (see § 5.3.1) Set
SINGLE
system option.
2. Connect voltage test leads on Phase, Neutral and Ground cables considering the
colours as shown in Fig. 165).
3. Connect the transducer current clamp on L1 Phase cable as shown in Fig. 165)
respecting the clamp’s arrow direction indicating the current standard sequence from
generator to load.
On Real Time Values’ section screens always verify the positive
value of Active Power and the power factor relative to load which should be
normally inductive
before starting a recording. Reverse the clamp by 180 degrees on
cables in case of negative readings.
4. Supply the electrical installation under test in case this was temporarily put out of
service for meter connection. The values of parameters are shown by meter at display
in Real Time Values section (see § 5.2.4.1).
5. Press SAVE key if an instantaneous sample of display values (Instant) should be
saved (see § 5.7). Use HOLD function to stop the values at display if necessary.
6. Check all settings before start a recording (see § 5.4). Press GO/STOP key to enable
and disable a recording on meter (see § 5.6).
