Figure 3-1. Generator Output Test
Basic Contact Quality Monitor (CQM) Test
This test of the contact quality monitor uses the Analyzer’s test load to
simulate a patient’s skin resistance in contact with the dual element
neutral/dispersive electrode pad.
Note
Perform this test on electrosurgical units without energizing the
generator output. Do not connect the ESU active electrode to the
Analyzer during this test.
The CQM (REM) test is intended for the neutral/dispersive electrode of
monopolar ESUs equipped with a contact quality monitor. The
neutral/dispersive electrode is actually two separate pads attached to the
patient’s skin. The CQM (REM) circuit issues an alarm only if the patient
loses contact with one or both of the two pads. See Figure 3-2 for a diagram at
the end of this section.
