Setting Dielectric Break down Judgment Conditions

Peak voltage value fluctuations

Discharges are detected based on variations in the first peak voltages among multiple pulses of

each applied voltage.

If the amount of variability in the first peak voltages for multiple pulses exceeds the set threshold,

the instrument will conclude that discharges are occurring.
