B. Appearance and Key function
I. Display Interface
Display interface is large-screen LCD, it can display voltage, current, power, energy parameters at the same time.
II. Display format
1. Power: test range: 0~2kW
within 1KW, the display format is 0.0~999.9W;
1KW and above, the display format is 1000~2000W.
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: 0~20A
Display format: 0.00~20.00
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.
4. Choose measuring range
Step1: Long press the key until the power area display “Curr”, then release the key
Step2: At this moment, the current area display “100A”, short press the key to switch between“100A”and “50A”, to prompt the range of the external shunt is 100A/75mV or 50A/75mV, please note that this meter can only use these two specification shunt.
Step3: Long press the key to exit the setting state or after no operation within 3 seconds it will store automatically and exit the setting state.
