   • 4-d : Display Mode Setting

1-U: Voltage Calibration:

While on 1-U , Press the button to enter the voltage calibration mode, release it and press again, the voltage will be adjusted; release the button and then press it to adjust step by step; repeat the setting and save the settings during the flash of the screen. And there is an installation.

2-b: Battery type adjustment:

• While on 2-b, press the button to change the type of battery, press one by one, it will be shown: 1.2V _ 2v_3.2v_3.7v_12v (when setting up the corresponding type of battery, release the button, save and exist settings with a blinking screen .)
  • 1.2 V : Ni-MH battery, each battery 1.2 V
  • 2 V : Lead-acid battery, each battery 2 in
  • 3.2 V : Lithium-Iron Phosphate Battery, each battery is 3.2 V
  • 3.7 V : Polymer lithium battery, each battery 3.7 V
  • 12 V : Lead-acid battery, each battery 12

3-C: Setting the number of batteries:

1. During the 3-C setting, press the button to enter the number of batteries in the setting.
2. Release the button and press again, the value will be adjusted; release the button, and then press i T to decrease the adjustment; Repeat the setting for the appropriate number of batteries.
3. Different range for different battery types:
   • 12 V Lead-acid battery: 1-10 sections
   • 3.7 V Lithium battery: 2-28 sections
   • 3.2 V Li-ion battery: 2-32 sections
   • 2 V Lead-acid Battery: 3-60 sections
   • 1.2 V Battery Ni-MH: 10-70 sections
4. Set to the appropriate mode, save the settings during the flash of the screen and exist settin

4-d: Display Mode Setting

1. In 4-d mode, press the button to enter setup mode.
2. Release the button, press it as soon as one mode is shown: V-voltage,% power percent (these two will be in a cyclic display)
3. Set to the appropriate mode, save the settings during the flash of the screen and exist settings
