The MPH Option allows the tester to output the waveform of the MegaPulse DF-1 Fig. A.2 Isolation Tester. If ordered with the TMM TestMinder computer control option, the tester can be set to automatically conduct the first 490 cycles of the test, then stop testing to allow the operator to monitor the last 10 cycles. Here are voltage and current waveforms of the test. Waveform.
The test signal includes the waveform cutoff at 750V/18mSec as required by the Standard.
