Performing Patient Auxiliary Leakage Tests
Note
The Patient Auxiliary leakage test is available
when the AN/NZS3551, IEC60601, or
ANSI/AAMI ES1-1993 standard is selected.
To measure the leakage current through each applied
part or lead and selected combination of lead connections
(all other or between two), press the softkey labeled
Patient Auxiliary from the Leakage Test main menu
shown in Figure 18. Figure 23 shows the electrical
connections between the Analyzer and the DUT during a
Patient Auxiliary Leakage Current Test.
The Patient Auxiliary Leakage test adds a diagram of the
applied parts connection posts to the display, as shown in
Figure 22. In the Figure, the applied parts post RA/R is
shown above the other posts. This indicates that the
leakage measurement is being made from RA/R to all
others. To move to the next applied part post, press .
The first post will appear inline with the other posts while
the LL/F post appears above all others. This indicates the
second leakage measurement is being made from LL/F to
all others. Continue pressing  or  to move from one
connection post to another and noting the measured
current in the display.
After each post is isolated individually, the Patient
Auxiliary Leakage test measures current of three different
combinations of posts tied together: RA/R and LL/F, RA/R
and LA/L, or LL/F and LA/L.

Within the Patient Auxiliary Leakage test, a number of
fault measurements can be made. Pressing 
switches the polarity of the mains voltage applied to the
Analyzer’s test receptacle between Normal, Off, Reverse,
and Off. Pressing  opens and closes the neutral
connection to the Analyzer’s test receptacle. Pressing
opens and closes the earth or ground connection to
the Analyzer’s test receptacle.
