11.2.4 Clamps C-6A
Clamps C-6A are designed to measure AC currents with frequencies up to 10 kHz for range 10
mA…10A. As optional accessories for instruments produced by SONEL S.A., they are compatible
with power quality meters of PQM series and multifunctional meters of MPI series.
The output signal is a voltage proportional to the measured current at the sensitivity of 100 mV/A.
It is introduced via a cable (length: 1.5 m) ended with a plug suitable for a socket in the meter.
The arrow marked on one of the clamps indicates the direction of current flow. It is assumed
that the current flows in the positive direction if it flows from the source to the receiver. This orienta-
tion of clamps is required for the correct power measurement.
NOTE!
Do not use non-insulated clamps for conductors with a potential exceeding 600 V with
respect to the ground, in systems with the measurement category higher than III and
systems of measurement category IV with potential exceeding 300 V.

e) Total Harmonic Distortion ........................................................................................................ <1%
f) current constant component ................................................................................................... none
g) permanent magnetic field .............................................................. <40 A/m (Earth's magnetic field)
h) variable, external magnetic field ............................................................................................. none
i) conductors in the immediate vicinity ......................................................................... no current flow
