| In order for a live-line tester to be used to test and prove dead a high voltage circuit, what must be done to verify the ability of the tester to detect a voltage? |
| A) The live-line tester should be checked by connecting to a known high voltage source only before testing the circuit to be worked upon. |
| B) The live-line tester need not be checked prior to testing the circuit to be worked upon as long as it has not been declared inoperative. |
| C) The live-line tester should be checked by connecting to a known high voltage source before and after the circuit to be worked upon is tested. |
| D) The live-line tester should be checked by connecting to a known high voltage source only after testing the circuit to be worked upon. |
