Value of the alarm threshold.
Measurement result.
Case where the measurement is
below the alarm threshold.
The clamp is connected.
3.10.4. ERRoR InDICAtIon
The commonest errors in the case of a current measurement are:
The clamp is not connected.
The current measured by the clamp is too low. Use a clamp having a lower ratio or pass the conductor through the clamp
several times to increase the measured current.
For help with connections or any other information, use the on-line help.
The frequency is too unstable for the measurement. In this case connect the cor-
responding mains voltage between L and PE. The device will then synchronize to
the frequency of the voltage and will be able to measure the current at this same
frequency.
I
Here, the conductor passes through the clamp 4 times. You will
have to divide the measured current by 4 to know the true value
of I.
The current measured by the clamp is too high. Use a clamp having a higher ratio.
