7–3–5 ECG Leakage Current Test (Continued)
Meter Procedure
The Dale 600/600E provides five snap type ECG buttons for testing patient leads. Snap on all patient leads to the
meter and assure that the ground clip is connected to the system’s ground terminal.
CAUTION
Line voltage is applied to the ECG leads during this test. To avoid possible electric shock haz-
ard, the system being tested must not be touched by patients, users or anyone while the ISO
TEST switch is depressed.
When the meter’s ground switch is OPEN, don’t touch the unit!
Follow these steps to test the ECG module for leakage current.
1. Turn the LOGIQ 400 unit OFF.
2. Plug the unit into the meter, and the meter into the tested AC wall outlet (Refer to ILLUSTRATION 7–10).
3. Plug the black chassis cable into the meter’s “CHASSIS” connector and attach the black chassis cable clamp to
an exposed metal part of the LOGIQ 400 unit (Refer to ILLUSTRATION 7–10).
4. Connect the patient leads to the corresponding snaps located at the upper front of the Dale 600/600E. Lead no-
menclature for this test is not important (Refer to ILLUSTRATION 7–10).
