Characteristics
- Accuracy: 5% +0.5 A
- Capture time: 10 periods of the signal frequency (200 ms
at 50 Hz)
- Range for use:
≥
5 A peak for the first period of the signal
3.8 Power measurement (W)
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”.
3. Connect the clamp on the system selected for power
measurement, complying with the following instructions:
- 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.
The “
➭
“ arrow on the jaws, must be directed in the
direction of power circulation from the source to the load.
In which case:
- the “+” sign corresponds to power consumed by the
load.
- the “-” sign corresponds to power supplied by the load.
