Description:
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.

D. Button
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.
E. Notes
1. This module is suitable for indoor, not outdoor use.
2. applied load can not exceed the rated power.
3. The wiring order can not be wrong.
Package include:
