3.8 Power measurement (W var VA)
1. Connect the measurement leads to the instrument’s
terminals, complying with the polarities indicated: red lead
on the “+” terminal and black lead on the “COM” terminal.
2. Set the rotary switch to position “W”(single phase
measurement).
3. Make a long press on the yellow key for measurement on
balanced 3 phases system.
4. Connect the clamp on the system selected for power
measurement, complying with the following instructions:
SINGLE PHASE SYSTEM
- Connect the measurement cables for voltage
measurement, red cable on phase, black cable on neutral.
- Clamp the conductor carrying the current to be measured,
check for proper closing of the jaws and for foreign bodies
in the gap.
BALANCED 3 PHASES SYSTEM
- Connect the measurement cable for voltage
measurement, red cable on phase 1, black cable on
phase 2 (U
12
measurement).
- Clamp the conductor of phase 3 (I
3
measurement).
