Suggested cause and action
A stable value for the leakage current cannot
be measured. A likely cause may be an unsta-
ble line voltage. Take measurements at another
time.
The operating voltage for compensation of
resistive leakage current measurement is out of
range (0.4 to 0.9 p.u. of arrester Ur). Verify the
value given as described in section 5.3.3.1.
The sensor ID was not recognised by any
locally present sensor. Wait 30 seconds before
retransmitting again. If contact still cannot be
established, check:
a) the chosen sensor ID is present at this station
b) the distance and orientation to the sensor is
as described in section 4.
c) interference from a high frequency source
d) battery status to ensure the transceiver
battery voltage is sufficient.
e) antenna status to ensure it is correctly
enabled.
Note! If none of the above are found to be the
cause, then consider the following:
When the energy in the sensor falls below a certain
level, the sensor switches off the listening function
(to conserve energy for recording) until such time
that the energy level is sufficient again for com-
munication. This may occur if many attempts to
communicate have been made in a row or because
there is insufficient sunlight and/or electrical field.
Should unexplained difficulties occur during com-
munication, it is suggested to wait until another time
to make measurements or else install a 9V battery
in the sensor.
