ClosureRFG Radiofrequency Generator
11-3
Electrical Safety Tests 110-120 V
Electrical Safety Tests 110-120 V
Warning
High Voltage
Do not touch the equipment during the isolation tests.
1. Use the variable autotransformer and the DVM to set the line voltage to 132 V. Do not
exceed 140 V.
2. Plug the line cord of the ClosureRFG radiofrequency generator into the leakage tester
for all tests.
3. For source leakage and isolation tests, use the Biomed Test Cable to access patient
connections. Short the electrodes and thermocouple wires together for testing.
4. For the 25 A test, connect the ROD-L leads to the chassis ground lug, and to the
ground pin of the power cord.
