The "Operation Manual" (actually a single sheet, one side) for the Kill-A-Watt Power Meter reads as follows:
"The watt/VA key is a toggle function key...The LCD will display Watts as the active power, where VA is the apparent Power..."
When I try to measure the power consumption of my small freezer and I select, for example, "Watts", the P4400 reads "64". Now, if I select "VA" it reads "90". Which is the right reading? How many watts is the freezer really consuming.
Can anyone tell me the difference between "real watts" and "apparent Power"?
