Maintenance: Check out Procedure
Verify the current leakage test results meet the requirements. Perform
electrical safety checks when indicated. All indicated electrical safety
checks require a pass/ fail indication for the steps performed. Record the
measurement values in your debrief.
1. Verify the equipment does not propose any health hazard. See
Leakage (AC line) Current Test"
Current Tests" on page 4-26, for more information.
2. Verify all exposed metal is properly grounded. See
Resistance Test" on page 4-24 for more information.
