Isolated Patient Lead (Source) Leakage–Lead to Ground
10-7-6-1
Definition
This test measures the current which would flow to ground from any of the isolated ECG leads. The
meter simulates a patient who is connected to the monitoring equipment and is grounded by touching
some other grounded surface. Measurements should be made with the ground open and closed, with
power line polarity normal and reversed, and with the ultrasound console Off and On. For each
combination the operating controls, such as the lead switch, should be operated to find the worst case
condition.
Equipment damage possibility. Never switch the Polarity when the unit is powered ON. Be sure
CAUTION
to turn the unit power OFF before switching the polarity using the POLARITY switch. Otherwise,
the unit may be damaged.
