On my P15 the Power Meter shows about 300 Watts as the output of the P15, but on the Status Page 539 Watts is displayed. Why?
I know the power consumption of the attached equipment is about 539W (when in idle) as I measured it with a separate high quality power meter I have (and it matches what the manual says for idle power). Plus the consumption of 6.5A at 539W matches given the power factor of the attached equipment. Also, the 65% load figure on the Status Page matches the 6.5A. (6.5A x 119.7V) / 1200 VA = 65%. So everything matches up perfectly, except the Power Meter is showing just over 50% of the number it should show.
Does anyone know why?
