reference the procedure in the IEC 60601-1. When using the Dale 600, switch the meter’s function
selector to the LEAD-ISO. Select the ALL position on the lead selector. Depress the rocker switch to
ISO TEST to test lead isolation.
NOTE: It is not necessary to test each lead individually or power condition combinations as required in
previous tests.
10-6-8-1 Data Sheet for ECG Leakage Current
The test passes when all readings measure less than the value shown in the table below. Record all
data on the PM Inspection Certificate.
CAUTION
Line voltage is applied to the ECG leads during this test. To avoid possible electric shock
hazard, the system being tested must not be touched by patients, users or anyone while the ISO
