This is an IEC 60601 Defibrillation-proof tester. For the Energy Reduction test, joules consumed in the 100Ω resistor are immediately displayed after each pulse. The MegaPulse D5-PF tests protection against the effects of defibrillation (Common Mode, Differential Mode) and Energy reduction test (EC-13) and as noted in the Standards shown above. The MegaPulse D5-PF outputs a 360J Defib-proof test pulse per IEC 60601-1 for the Energy Reduction Test. It can also be used as a Defibrillator Lead Tester.
