7-Patient leakage current test under the condition of applied parts plus mains voltage
Overview
Patient leakage current test under the condition of applied parts plus mains voltage: In the case
of applied parts plus 110% mains voltage, select the applied part terminal. The leakage current
test is performed between the selected application part and the ground. Under the displayed
normal polarity and reversed polarity conditions, measure the leakage current for the
application part plus 110% mains voltage.
The following output conditions are required for this test:
Normal Polarity;
Reversed Polarity
Test process
• Preparations
Tap CAL (soft key 2) to perform calibration for the test of applied parts plus mains voltage.
1. Disconnect all patient leads and test the output connection between the leads and the DUT.
2. Press CAL to start calibration, as shown in the following figure:
If the calibration fails, the saved value is used until an acceptable calibration value appears.
The Esc/Stop key is invalid during calibration.
3. After the calibration is completed, the patient leakage current test under the condition of
applied parts plus mains voltage appears on the screen.
• WARNING
1. If two beeps per second are generated during the calibration, high voltage occurs on the
applied part terminal.
2. High voltage may occur on the applied part terminal during the measurement test.
• Performing the test
1. On the main panel, insert the DUT plug into the auxiliary output on the front panel of the 601
PRO tester when there is no power on the output end.
2. Connect the applied part of the device to an available applied part terminal of the 601 PRO
tester.
3. Tap 7. The patient leakage current test under the condition of applied parts plus mains
voltage appears on the screen.
