modname=editor

1. Working voltage: 80 ~ 270VAC

2. Test voltage: 80 ~ 270VAC

3. Rated power: 100A/22000W

4. Operating frequency: 45-65Hz

5. Measurement accuracy: 1.0 grade

1. This module is suitable for indoor, please do not use outdoor.

2. Applied load should not exceed the rated power.

3. wiring order can’t be wrong.

4. It can't be used in some circuit such as inverter or silicon controlled.

Function

1. Electrical parameter measurement function (voltage, current, active power, energy).

2. Running time function (records the load aculated operating time).

3. The reset function of energy and running time keys.

4. Balight function.

5. Store data when power-down (store the aculated energy ,running time ,display it, the state of balight on or off).

6. Large-screen LCD (display voltage, current, energy, active power, the aculated running time)

The descrtion of keys/LCD function

UP 1. In normal display state, short pre the UP key will red circularly display time, power, energy, current, voltage.

2. Short pre the UP key will exit the reset state when energy and time are in the reset state.

DOWN 1. In normal display state, short pre the DOWN key will sequential circularly display voltage, current, energy, power, time.

2.Short pre the DOWN key will exit the reset state when energy and time are in the reset state.

SET 1. In energy or time display state, long pre 3 seconds will enter into the energy or time reset state.

OK 1. In the normal display state, short pre the OK key will turn on or off the balight .

2. In energy or time reset state, pre the OK key will reset the energy or time and quit the reset state.

Function setting

Reset ulative time, energy setting

1. In normal display state, short pre UP or DOWN key to switch to the ulative time or energy display menu.

2. Long pre the SET key for 3 seconds until fing screen appears, then release the key

3. Pre OK key, the ulative time or energy data will be cleared, and LCD screen returns to the ulative time or energy display it, if you don't want to clear, then pre UP or DOWN key to exit the reset state and return to the menu display.

Note:/p>

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 hines, televisions, computers, etc.), P
