2) Display at the connection pictograph: PE interrupted (x) or
bottom protective conductor bar interrupted with reference to the
keys at the test plug
Cause: Voltage measuring path interrupted
Result: Measurement is disabled

Probe is not detected, probe not connected
Remedy: Check probe connection.

Clamp is not detected:
– Clamp is not connected or
– Current through clamp is too small (partial earthing resistance too high)
or
– Transformation ratio set incorrectly
Remedy: Check clamp connection and transformation ratio.
Check the batteries in the METRAFLEX P300 and replace if
necessary.

If you have changed the transformation ratio at the test instrument, a
message appears prompting you to change the setting at the current
clamp sensor as well.

Voltage too high at clamp input or signal distorted
The transformation ratio parameter selected at the test instrument might not
correspond to the transformation ratio at the current clamp sensor.
Remedy: Check transformation ratio or test setup.

Battery voltage is less than or equal to 8 V.
Reliable measurement is no longer possible.
Storage of measured values to memory is disabled.
Remedy: Rechargeable batteries must be recharged or replaced
towards the end of their service life.
