Lead to lead leakage test record
Table 10-16 on page 10-27 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 10-9 on page 10-14
• Table 10-10 on page 10-14 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 test (Scanner) power cable into the receptacle on the panel of the meter.
3.) Connect the ECG cable to the scanner and the Patient leads to the analyzer.
4.) Select the Lead to lead or Patient Auxiliary leakage function on the meter.
NOTE: Consult the manufacturer’s user manual of the Safety Analyzer.
• Test opening and closing the ground with the scanner on and off as indicated in Table 10-9 or
