Patient Auxiliary, single fault, earth open
This test measures the patient auxiliary current under a single fault condition (earth open). The current is
measured through the Measuring Device with S1 closed, S8 open and S5 normal and then S5 reversed. The
maximum allowed values are as follows:

Warning
40Va.c. test voltage applied to lead
Plug the lead into the Analyser outlet socket, and also into the Analyser IEC socket.
The IEC test performs a continuity and polarity check on the
Live
and
Neutral
conductors and confirms that
there are no breaks or cross wiring in these conductors.
Note: Earth Bond and Insulation tests also need to be made to confirm the electrical safety of IEC leads.
