10-6-8 Isolated Patient Lead (Source) Leakage – Lead-to-Lead
When using any calibrated Electrical Safety Analyzer tool compliant with AAMI/ESI 1993 or IEC 60601
or AS/NZS 3551, switch the meter's function selector to the LEAD-LEAD position (or equivalent function
in the device).
Select and test each of the ECG lead positions (except ALL) on the LEAD selector, testing each to the
power and ground condition combinations found in:
• Table 10-11 on page 10-17
or
• Table 10-12 on page 10-17
as applicable.
Record the highest leakage current measured.
10-6-8-1 Lead-to-Lead Leakage Test Record
Table 10-16 below shows a typical format for recording the patient lead-to-lead leakage current.
Measurements should be recorded from each lead combination under each set of test conditions
specified in:
• Table 10-11 on page 10-17
or
• Table 10-12 on page 10-17
as applicable.
Record all data on the EQC inspection certificate; also known as Patient Auxiliary Current.
1) Connect Safety analyzer to wall AC power outlet.
2) Plug the equipment under the test power cable into the receptacle on the meter's panel.
3) Connect the ECG cable to the Vivid™ S60/Vivid™ S70 ultrasound system and the Patient leads to
the analyzer.
4) Select the Patient lead leakage function on the meter.
5) Test opening and closing the ground with the Vivid™ S60/Vivid™ S70 ultrasound system ON and
OFF, as indicated in Table 10-11 on page 10-17 or Table 10-12 on page 10-17, as applicable.
NOTE: Refer to the safety analyzer’s user manual that will be used to perform the tests.
