Temperature monitoring
The tester is provided with internal temperature monitors to ensure
sensitive components are not overheated. High rates of testing may
cause this situation, especially with long Earth Continuity tests.
Setting Earth Continuity test times to 2 secs will increase operating
time. If the message Hot appears on the primary display, leave the
tester to cool down. Once the temperature is below the trip level the
display will revert to normal for the rotary switch position selected.
Multiple Earth connections:
In general, multiple earth connections to an EUT (e.g. water pipe
connections to a water heater) can cause difficulties in measurement.
This has previously needed the additional earth connections to be
isolated.
The Europa PAC Plus tester is capable of testing earth connections
in the presence of additional earth paths. The Leakage measurement
will also be correct due to the differential leakage current, rather than
the earth lead current. Measurements are thus assured without
special precautions.
