E&OE Overview Question : Why is the Measurement incorrect? Voltage x Current = Power. But Power is less than the actual Test Voltage x 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)We are only interested in the Active Power here.P = U x I x cosφ, cosφ 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 is 0-1. So purely Resistive Load Test Time, P is substantially equal to or close to U x I. When Inductive or Capacitive Load Test (Such as refrigerators, washing machines, televisions, computers, etc.) P<UxI. As for how much to keep the power factor related to the specific. Different for each Appliance Power Factor.Note:This Module is suitable for Indoor only. Not for Outdoor use. Applied Load CANNOT Exceed the Rated Power. The Wiring Connection must be Correct or else the Module can be Damaged.
