The PSP uses a Motorola microcontroller. This means that Intel-based software,
such as Windows, might interpret the floating-point data transmitted from the
Power Series Plus as “swapped”.
•
A Watt/VAR/PF meter cannot access the Volt, Amp or Hertz registers and other
meters cannot access the Watt, VAR or PF registers.
•
VARs and PF are negative values if leading and positive if lagging.
•
Min and Max for VARs and PF disregard lead and lag. The smallest absolute
value is always the Min and the largest absolute value is always the Max.
