5.2.5 Disconnection
After the Advanced CT test is finished, disconnect the CT under test from CT Analyzer.
1. Wait until the red LED on CT Analyzer is off.
2. Disconnect the measurement leads starting at CT Analyzer.
WARNING
Death or severe injury caused by high voltage or current possible
As long as the red LED on the CT Analyzer test set is flashing, the output is active and
lethal voltages can occur due to the high energy stored in external inductors.
► Do not disconnect measurement leads while the red LED on CT Analyzer is flashing.
► Always wait until the red LED is off before disconnecting measurement leads.
