4. Each function of the 5 sub menu :
   1- -: Select built-in preset battery specification: lithium battery, lead acid battery, LFP battery.
   2- -: Setting Delay Time Delay OFF/ON, and select Delay Time
   3- -: The voltage of percentage 0 to 100 could be customed.
   4- -: Buzzer switch and alarm value setting.
   5- -: Calibrate the instrument voltage again.

5. Press , select the menu to enter, long press to quit.

6. All parameters are subject to the last save.

explanation:

1–: Quick change battery type
Under this menu, you can change the default parameters speedy:
L represents the lithium battery, and the latter figure is the series quantity;
F represents the lithium iron phosphate battery, and the latter figure is the series quantity;
P
stands
for
lead­acid
batteries,
and
the
numbers
behind
represent

E.g.
L3 represents 3 string lithium 4.2V”3S=12.6V.
L7 represents 4 string lithium 4.2V”7S=29.4V.
F4 represents 4 string lithium iron phosphate battery 3.2V4S=12.8V.
F8 represents 8 string lithium iron phosphate battery 3.2V8S=25.6V.
P12V stands for lead-acid 12V batteries.
P24V stands for lead-acid 24V batteries.

Note: Please set parameters according to the battery specifications, otherwise, the percentage value is inaccurate; the voltage value is accurate.
All parameters are subject to the last save.

The menu customizes the percentage of the upper and lower voltage, and after changing this parameter, the product can be applied to nickel-hydrogen, fuel cells and Enter the menu 3–,as shown in P5:

Left side is power 0%, represents the low battery voltage.
Right side is power 100%, represents the full battery voltage.
Setting steps: Enter the menu 3–, Press to adjust the setting voltage, press to carry, press to save parameters.
If you don’t need to change other parameters, press to quit.

Notes: The input value must not exceed the instrument working voltage. If the value on the left side is greater than or equal to the value on the right side, the save is invalid.

4–: Buzzer alarm value setting and ON/OFF
This menu customizes buzzer working voltage and red alarm value.
Enter the menu 4–,as shown in P6:

The left side is the buzzer ON/OFF status.
The left side is for setting buzzer alarm voltage.

Setting steps :
Enter the menu 4–, press to take the buzzer ON or OFF, press to carry, long press to save. If you don’t need to change other parameters, press to quit.
Notes: When the buzzer works, the red lightning symbol flashes in sync. If the switch is OFF, it will be no working.

5–: Calibrate the instrument voltage again
Enter the menu 5–,as shown in P7:

Before entering the calibration interface, please provide an accurate 20V operating voltage for the instrument.
To prevent misoperation, long press to enter the menu in 5– status, and then the meter will be automatically calibrated according to the supplied voltage. But it cannot be calibrated if the voltage range is not between 19 and 20V.

Notes: Please provide an accurate 20V operating voltage for the instrument to ensure correct calibration, otherwise, the error will be bigger.
When the calibration is complete, the instrument will automatically exit this menu and display the normal working interface.
