Isolation Lead Leakage
See Figure 4-7, ECG Lead Isolation Test: All Leads and Individual Leads.
You can do the following two tests in an all-lead or individual-lead mode. The
selected lead or leads are connected to the AAMI load with line voltage
applied to the lead(s). The test receptacle is fixed with normal polarity, closed
ground, and closed neutral during these tests.
WARNING!
During any isolation lead leakage test, 120 V at 1 mA is present
on the ECG leads. This is an electrical shock hazard.
