Hi,
I've been looking at various test equipment specs and see specifications like the following:
Max differential measuring voltage (DC + Peak AC): ±500V
Common mode voltage (DC + Peak AC): ±500V
Can someone please explain what the DC + Peak AC means. Does the Peak rating mean peak to peak on an AC signal, or the 0V to Peak AC voltage?
Also, am I right in assuming that if I had a 400V DC signal, and a standard AC sinusoidal signal sitting on it, then the AC signal can not be more than 100V (measured center to Peak)?
Could the item with the above rating be used to measure mains 230V RMS AC, which is 325V centre to Peak, or 650V Peak to Peak?
Regards,
Sijmen.
