In Case of Failure
Check any broken of the enclosure. Replace any defective part.
Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet; verify it is grounded and is free of other wiring abnormalities. Notify the user or owner to
correct any deviations. As a work around, check the other outlets to see if they could be used instead.
Change another probe to confirm if the fail is caused by console.
If the leakage current measurement tests fail on a new unit and if situation cannot be corrected, submit a Safety
Failure Report to document the system problem. Remove unit from operation.
If all else fails, stop using and inform the Customer Service Engineer for analysis and disposal.
LIMITS
For CF applied parts
10μA in Normal Condition
50μA in Single Fault Condition
For BF applied parts
100μA in Normal Condition
500μA in Single Fault Condition
A.7 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage, through a limiting resistance,
to selected applied part terminals. Current measurements are then taken between the selected applied part and earth.
Measurements are taken with the test voltage (110% of mains) to applied parts in the normal and reverse polarity
conditions as indicated on the display.
The following outlet conditions apply when performing the Mains on Applied Part test.
Normal Polarity;
Reversed Polarity
Preparation
To perform a calibration from the Mains on Applied Part test, press CAL (SOFT KEY 2).
1. Disconnect ALL patient leads, test leads, and DUT outlet connections.
2. Press CAL to begin calibration, as shown:
If the calibration fails, the previously stored readings will be used until a passing calibration has occurred. Also, the
esc/stop key has no effect during calibration.
3. When the calibration is finished, the Mains on Applied Part test will reappear.
