Value of the alarm threshold.
Measurement result.
Case where the measurement is
below the alarm threshold.
The clamp is connected.
3.11.5. 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 help function.
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.
