Precautions
This module is suitable for indoor, please do not use outdoor.
Applied load should not exceed the rated power.
Wiring order can't be wrong.
It can't be used in some circuit such as inverter or silicon controlled.
Note:
There are three types of power: active power (P represents / unit W), reactive power (Q represents / unit Var), apparent power (S represents / unit VA).
And the power of our product is active power.
Active power is calculated as: P = U * I * cosφ, cosφ represents the power factor, for purely resistive loads (such as incandescent, heater, etc.) the power factor is generally close to 1, for inductive load and capacitive load, the power factor is between 0-1; so when you test the purely resistive load, the power(P) is substantially equal to or close to U * I; but when you test inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc.), P
Packing list:
1 x PZEM-021 AC Voltmeter Ammeter
Note:
Due to manual measurement, it may vary from 1 cm to 3 cm. Color deviation might exist due to different monitor settings and light, please kindly unders
