Active power is calculated as: P = U * I * cosφ, cosφ represents the power factor, purely resistive loads (such as incandescent, heater, etc.) the power factor is generally close to 1, inductive and capacitive load load power factor 0-1; therefore purely resistive load test time, P is substantially equal to or close to U * I; test inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc.) when, P Less than U * I As for the specific number to keep the power factor related to power factor different for each appliance, please show table prevail.

Display voltage, current, power, energy parameters from the large-screen LCD screen simultaneously.
1. Power: measurement range 0 ~ 22kW
1kW display format within 0.0 ~ 999.9W;
From 1kW display format 1000 ~ 9999W;
10kW above the display format 10.0 ~ 22.0kW.
2. Power: measurement range 0 ~ 9999kWh
10kWh within the display format 0 ~ 9999Wh;
Above 10kWh display format 10 ~ 9999kWh;
3. Voltage: Test Range 80 ~ 260V
Display Format 80 ~ 220V
4. Current: Test Range 0 ~ 100A
Display Format 0.00 ~ 99.99A.
1. The backlight control
By short press the button to turn on or off the backlight, the backlight status automatic storage.
2. The power cleared
Step 1: Press the power button 5 seconds until the digital display window flashes, then release the button;
Step 2: If you press the button again, the consumption data is cleared and cleared quit flashing;
Step 3: If you press the button again 5 seconds long until no flashing, the charge data is not cleared and exit cleared.
3. The power to set the alarm value
Step 1: Press the button, when the LCD screen display "SET CLr" after the release button, set the value into the power status report;
Step 2: Power area displays the current value of the power alarm and the lowest digit starts blinking, then you can press the button of the digital +1, when there is no key operation more than three seconds, automatically switches by short digital set as above;
Step 3: After setting, press the button more than five seconds to automatically save and exit, the scope of active power threshold set for the 0.0 ~ 22.0kW.
