No. Phenomena Reason Solutions
1
The measured value
always shows Zero
values.
1.1
0.5A is the low cut value for this
sensor. Therefore the actual load
current (after multiplying the CT
ratio) must be higher than 0.5A.
Do nothing, it is the standard feature
of the sensor.
In case the measured load is too
small, please make more loops on
the CT, so that the measured current
will be multiplied by the number of
the loops.
2
The measured value is
not as expected
2.1 The CT ratio is incorrect
Please check the actual ratio of CT
and the configuration of CT in the
wireless transmitter again.
2.2
Loosed connection of M12
connector of the transducer and
wireless transmitter.
Check whether the M12 connector is
firmly connected?
2.3 Wrong A and B values
Check the A & B in the configuration
of the Wireless transmitter.
Normally, A=1 and B=0. A & B can
only be changed to other values
when the transducer was re-
calibrated by AC current calibrator.
3 HW_Error = 1 3.1
