For defibrillators that can be operated on line power, measure leakage current from patient leads to ground. Perform the test with the defibrillator on and with the ground wire intact and open, in all normal operating modes. DO NOT MEASURE LEAKAGE CURRENT FROM PADDLES OR DEFIBRILLATION OR PACING ELECRODES WITH THE DEFIBRILLATOR CHARGING OR CHARGED OR WITH THE PACEMAKER ON!
