NMGS PMC PROCEDURE (continued)
6.2.1.4 Set the safety analyzer GROUND switch to NORMAL. Set
the POLARITY switch to OFF.
6.2.1.5 Plug the machine’s AC power cord into the safety analyzer.
6.2.1.6 Apply the analyzer’s test lead to a cylinder yoke bolt.
6.2.1.7 What is the value displayed on the safety analyzer? ___ ohm
(0-0.1)
6.2.2 Circuit Isolation
6.2.2.1 Disconnect the respiratory volume sensor cord from the
interface panel.
6.2.2.2 Using a multimeter set to its
highest resistance range apply
the test leads between the yoke
bolt and circuit common at the
volume interface test pin. Refer
to the corresponding illustrations
for the proper test pin location.
There shall be no continuity
between these points.
6.2.2.3 Reconnect the respiratory volume
sensor cord to the interface panel.
6.2.3 Chassis Leakage Current
6.2.3.1 Apply the analyzer test lead to a
cylinder yoke bolt.
6.2.3.2 Set the safety analyzer to the
CHASSIS LEAKAGE CURRENT
position.
6.2.3.3 Record the total leakage current with the Polarity and
Ground switches set as follows:
Ground Polarity
Normal Normal
Open Normal
Open Reversed
Normal Reversed
6.2.3.4 Verify that the leakage current is 100* microamps or less in
each of the switch positions (110 microamps or less for the
220/240 volt power supply option).
6.2.3.5 300 microamps if external monitors are plugged into
convenience receptacles.
6.2.3.6 Shut off and unplug the safety analyzer. Remove the
anesthesia machine plug from the analyzer and plug it back
into the original AC receptacle.
