8.3.1 C-4(A) current probe
The C-4(A) probe is used to measure the alternating current
in medium and high power electrical installations. The output sig-
nal is voltage proportional to the measured current. The output
signal is supplied by a 1.5-meter lead with a pin adapted for the
socket in the meter.
The arrow located on one of the jaws indicates the current
flow direction. It is assumed that the current is flowing in the pos-
itive direction if it is flowing from the source to the receiver. Such
probe orientation is required for a correct power measurement.
Clamps with letter 'A' at the end of marking (e.g. C-4A) are
clamps with automatic type detection in compatible devices.
Other parameters are the same as in the case of clamps without
automatic clamp type detection.
Note
Currents above 1200 A must not be measured. The measurement time for currents above
1000 A shall be limited as follows:
