Bisx Patient (Sink) Leakage Current Test - GE Dash 3000 Service Manual

Acceptance criteria SFC – ground (earth), line or neutral open

BISx patient (sink) leakage current test

8-18
Functional and electrical safety checks: BISx (option) current leakage tests
If any reading with the ground open is greater than 500 uA, the BISx
fails this test. Contact GE Technical Support.
This test checks the patient cable leakage current from a 115 or 220VAC
source into the BISx. This test checks leakage current from the patient
cable connector of the BISx to ground. Refer to the instructions contained
with the safety analyzer to perform each test.
NOTE
*The MD represents the network and voltage measuring instrument
and its frequency characteristics per IEC 60601-1.
** Per IEC 60601-1, the impedance to protect the circuitry and the
person performing the test, but low enough to accept currents higher
than the allowable values of the LEAKAGE CURRENT to be
measured.
Refer to the instructions contained with the safety analyzer to perform
this test.
WARNING
Shock hazard. The following step causes high voltage at
the test body. Do NOT touch the test body.
1. With the Sensor Plus simulator connected to the BISx and the two
circular Sensor Plus simulator connections (test body) connected to
the leakage tester:
2. Configure the leakage tester as follows:
Polarity – NORMAL

Neutral – CLOSED

GND (Earth) – CLOSED
