FAQ

Why is the test data wrong?  Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?

Answer: There are three types of power:

Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)

Here we only talk about Active Power, for others, please google it:

P = U * I * cos, cos it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time,  P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.)  PAs for how much to keep the power factor related to the specific, Different for each appliance power factor.
