Large-screen LCD (display voltage, current, active power, energy at the same time) 6. Backlight function. Display format 1. Power: test range: 0~10kW Within 1KW, the display format is 0.0~999.9W; 1KW and above, the display format is 1000~9999W. 2. Energy: test range: 0~9999kWh Within 10KWh, the display format is 0~9999Wh; 10kWh and above, the display format is 10~9999kWh. 3. Voltage: test range: 6.5~100V Display format: 6.50~99.99V 4. Current: test range: 0~100A (0~20A) Display format: 0.00~99.99 Key 1. Backlight control Short press the key to turn on or off the backlight, the backlight has memory function, it can store the on or off state when power off. 2. Reset energy Step1: Long press the key until the power display area display CLr, then release the key. Step2: At this moment, the energy is flashing to prompt this is the energy reset state, if short press the key again, then the energy value is cleared and exit the reset flashing state. Step 3: If there is no operation within 5 seconds, it means the energy value is not cleared and will exit the reset state. 3. Set voltage alarm threshold Step1: Long press the key until the power display area display SET, then release the key. Step2: After enter this state, the voltage area display the current high voltage alarm value, the current area display the current low voltage alarm value and the last digit begin to flash, then you can short press to plus 1, when there is no operation over 3 seconds, it will switch the digit position automatically, from the high voltage alarm value to the low voltage alarm value, there are total six digits, the range of the voltage alarm threshold is 6.5 ~99.9V; Step3: After finish the setting, long press the key until the screen display PASS ,that means you set successfully and will exit the setting state automatically. Precautions 1. This module is suitable for indoor, please do not use outdoor. 2. Applied load should not exceed the rated voltage, current. 3. Wiring order can't be wrong. AC TYPE 1.

Current: test range: 0~100A/0~20A Display format: 0.00~99.99A Precautions 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. 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 * cos, cos 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 _x000D_ _x000D_
