CURRENT CLAMP
C-6A
USER MANUAL
Version 1.00 08.06.2022
1 Description
The C-6A clamp is designed to measure AC
currents with frequencies up to 10 kHz for range
10 mA...10 A.
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:
2.2 m) ended with a pin suitable for a socket in
the meter.
The arrow marked on one of the clamps indi-
cates the direction of current flow. It is as-
sumed that the current flows in the positive direc-
tion if it flows from the source to the receiver. This
orientation of clamps is required for the correct
power measurement.
2 Safety
NOTE!

Do not expose the clamp to water.

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 meas-
urement category IV with potential exceed-
ing 300 V.
3 Operation
To measure the current, open the clamp slight-
ly by turning the clasp, clamp it on the conductor
with flowing current and roughly center the con-
ductor relative to the clamp loop. Pay attention to
the direction of the arrow, to avoid the power
measurement error.
The gap (formed by the faces of the core) should
be kept perfectly clean.
4 Cleaning and maintenance
NOTE!
Apply only maintenance methods specified by the
manufacturer in this manual.
Before cleaning, disconnect the clamp from
the tested circuit and the meter. Do not spray the
clamps with water.
Remove the dust from the gap with a soft and
dry cloth. Periodically wipe the accessible iron part
of the jaws with an oil-soaked cloth to prevent
possible corrosion.
The clamp may be cleaned with a soft, damp
cloth using all-purpose detergents. Do not use
any solvents.
5 Dismantling and utilisation
Worn-out electric and electronic equipment
should be gathered selectively, i.e. it must not be
placed with waste of another kind.
Worn-out electric equipment should be sent to
a collection point in accordance with the law of
waste electrical and electronic equipment.
Before the equipment is sent to a collection
point, do not dismantle any elements.
Observe the local regulations concerning dis-
posal of packages.
