8.3.3 C-6(A) current probe
The C-6(A) is used to measure the alternating
current with frequencies up to 10 kHz in the
10
mA…10 A range.
The output signal is voltage proportional to the
measured current with the 100 mV/A sensitivity.
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 cur-
rent is flowing in the positive direction if it is flowing
from the source to the receiver. Such probe orien-
tation is required for a correct power measurement.
Clamps with letter 'A' at the end of marking (e.g. C-6A) 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.
Warning
Do not use the device on non-insulated conductors with a potential of
more than 600 V in relation to the earth and a measurement category
greater than III.
