• Function
  1. Electrical parameter measurement function (voltage, current, active power, energy)
  2. Voltage alarm function (over voltage alarm threshold, backlight and voltage flashing to alarm)
  3. The reset function of energy key
  4. Store data when power off
  5. Large-screen LCD (display voltage, current, active power, energy at the same time)
  6. Backlight function
  
• Appearance and Key function
• Display Interface
  Display interface is large-screen LCD, it can display voltage, current, power, energy parameters at the same time
• 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: 0~50A
  Display format: 0.00~49.99
  
• 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
• 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

  Recently had buyers who had the connection error in dc table (with 50A or 100A external shunt), so briefly refocused to explain here, if buyers not according to the physical wiring diagram user contrast connection, a burn table shall not be liable for any situation. Note as following:
• 1. The No-Load condition (voltage measurement, don't connect the shunt and load)
  Dc power supply is negative table from the power supply/positive and negative electrode of test power supply are ok to directly from you.
  2. The loading status (have connected the shunt and load)
  Pay special attention to dc form cathode anode cannot connect the cathode of the power supply directly ,need to go through an external shunt terminal (although see the wiring diagram from the back of the meter is in a line, but the result is completely different)!
