Other Function

1. Backlight control
Short press the key to turn on or turn off the backlight.
2. Reset Energy
press the key over than 3 seconds can reset the energy.
3. Current Indication
Current has direction indication, if there is “-”, it means the current is re direction, otherwise it is forward direction.

Figure 2 Direction Indication
4. Energy Indication
Energy has direction indication, if there is “-”, it means the energy is re direction, otherwise it is forward direction.
The energy direction is judged according to the current direction, If the current is positive, the energy will increase, maximum is 999kwh, overflow will be maintained, unless you reset it; if the current is re, the energy will decrease, maximum is -999kwh, overflow will be maintained, unless you reset it
5. Working Mode
Direct power supply: Direct supply by test voltage, test range is: 8-300V
Independent power supply: Working voltage range is: DC5-12V, test range is:0-300V

6. Data Preservation
Energy data and backlight state can be saved when power off.
