Use steps: choose one of automatic mode and manual mode
1 Steps for using the automatic mode this mode is easy to use, it is recommended that you use the automatic mode
1. Wiring and checking the current:
All wires from the positive or negative terminal of the battery are measured through the r. The correct wiring is that the coulomb counter shows positive current when charging and negative current when discharging. If not, it means that your r is red, and you can turn the r in re; if the current of the newly installed good coulomb counter is not zero at no load, you need to clear the current at no load.
2. Battery capacity reset:
After the first use or repment of the battery, the capacity value displayed by the is not the actual value of the battery, and a zero-capacity operation is required: after the battery is fully discharged empty, press and hold the key for 3 seconds, the capacity value and percentage are reset to 0%. When charging the battery, the capacity will automatically display 100% when fully charged. This process is completely automatic and does not require customers to set up, which is simple and convenient.
Special situation: the capacity does not display 100% after the charger is fully charged, you can manually fill up to display 100% by pressing the up on Note: press the up on without unpluing the charger

2 Steps for using the manual mode this mode is used when the customer knows the battery characteristics very well
1. Wiring and checking the current:
All wires from the positive or negative terminal of the battery are measured through the r. The correct wiring is that the coulomb counter shows positive current when charging and negative current when discharging. If not, it means that your r is red, and you can turn the r in re; if the current of the newly installed good coulomb counter is not zero at no load, you need to clear the current at no load.
2. Setting s:
The two s of battery rated capacity CA and full-charge automatic full-capacity voltage FV must be set.
Battery rated capacity is set in menu item: 11CA battery effective capacity;
The voltage of fully charged automatic full capacity is set in the menu item: 12FV full capacity voltage this voltage is recommended to be set to the highest virtual voltage displayed by the coulomb counter when the battery is fully charged and the power of the charger is not unplued .
3. Fill once:
After connecting the wires and setting the s, the watch will not display the battery capacity immediately. At this time, the battery icon and capacity are still empty, and the battery needs to be fully charged to display the remaining power normally. This needs special attention.

Use FAQ
1. Do I need to set s when using the coulomb counter?
Answer: No, this coulomb counter only needs to be connected correctly for the first use after receiving it, and then charge the battery after emptying the battery until the battery is fully charged. convenient. Special cases can also be set manually
2. Does the coulomb counter need to install a switch?
Answer: No, the backlight will be automatically turned off when the coulomb counter has no current. At this time, there is only 5mA current, which can be ignored.
3. Does the r measure the direction?
Answer: The coulomb counter displays positive current when charging, and negative current when discharging. If not, it means that your r is connected rely, you can turn the r in re.
4. During the discharging process of the battery, the power also decreases slowly. But the battery does not increase when charging?
Answer: The Hall r is not connected to the total positive pole or the total negative pole, and the charging and discharging circuits must p through the Hall r.
5. Why does the battery not charge or discharge, and the coulomb counter current shows a small current of a few tenths of an ampere?
A: Due to the of the device or the influence of ambient temperature, when the current is not 0 at no load, zero calibration is required.
6. The battery has been used for a time. I don't know how much AH the real capacity is. What should I do?
Answer: After the battery is empty empty, press and hold the on for 3 seconds, the capacity value and percentage will be reset to 0%, and the battery will be charged at this time. .
Special case: The capacity does not display 100% after the charger is fully charged, you can manually fill up to 100% by pressing the up on Note: press the up on without unpluing the charger
7. Can the battery capacity be set manually?
Answer: Yes, first set the effective capacity of the battery in the menu item 11CA, then fully charge the battery, and then press and hold the up on to manually fill it up to display 100% Note: press the up on without unpluing the charger
