3.12 WARNINGS
3.12.1 Power-On tests
Running a leakage or load test will operate the asset under test. Some assets, such as vacuum cleaners,
disc cutters etc can draw high initial load currents (Inrush current). The PAT400 will under these
circumstances report the asset has a short circuit.
If this warning is displayed, it is recommended the following actions are taken:
1) Where possible check the asset does not have a short circuit (the fuse would normally be blown in
such circumstances, prior to it being replaced).
2) Proceed ONLY if you believe the asset is not a true short circuit, but has a high inrush current.
3.12.2 Reversed supply
UK instruments:
The PAT400 will detect a reversed polarity (Phase – Neutral) supply and abort the initialisation.
The display will show the warning:
ERROR 82:
Mains polarity reversed
European instruments:
The instrument will pass initialisation and display the Home screen. The supply polarity will be
shown as “Reversed”.
