10-4-8-3 Dale 600 Meter Procedure
When measuring system chassis currents with the Dale 600, always use the CHASSIS selection of the
external/chassis function switch. This requires the ground clip lead and changing the meters switches
in accordance with the IEC 601-1.1. refer to the Dale 600 Instruction Manual for meter self-test and
operation. Record the highest leakage current measured.
Follow these steps to test the unit for leakage current.
1.) Turn the LOGIQ C Series unit OFF.
2.) Plug the unit into the meter, and the meter into the tested AC wall outlet
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 C Series.
4.) Set the tester's "FUNCTION" switch to CHASSIS position.
5.) Follow the test conditions described for respective test points shown in

10-4-8-4 Dale 600 Meter Procedure
The Dale 600 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. Select the
meter's LEAD-GND function. Select and test each ECG lead positions (except "ALL") of the LEAD
selector, testing each to the power condition combinations found in "PATIENT LEAD LEAKAGE" table
in the "PM CHECKLIST". Record the highest leakage current measured for each Power selection.
Line voltage is applied to the ECG leads during this test. To avoid possible electric shock
CAUTION
hazard, 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 C Series unit OFF.
2.) Plug the unit into the meter, and the meter into the tested AC wall outlet.
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 C Series unit.
4.) Connect the patient leads to the corresponding snaps located at the upper front of the Dale 600/
600E. Lead nomenclature for this test is not important.
