Generic Procedure on Leakage Current
Measurements should be made with the ground open and closed, with power line polarity normal and
reversed, and with neutral open and closed.
For each combination, the probe must be active to find the worst case condition.
NOTE:
Saline water pod should be insulated from floor and earth ground.

Type CF Patient Auxiliary current - ECG Lead to Probe
Reference the procedure in the IEC 60601-1. Measure current flow from Probe to all ECG leads
connected together. The maximum allowable limit for earth leakage current is shown in
.
