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 reversed, and you can turn the r in reverse; 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 replacement of the battery, the capacity value displayed by the fuel gauge is not the actual value of the battery, and a zero-capacity operation is required: after the battery is fully discharged (empty), pre 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 proce 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 long preing the up on (Note: long pre the up on without unplugging 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 reversed, and you can turn the r in reverse; 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 parameters: The two parameters 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 unplugged) . 3. Fill once: After connecting the wires and setting the parameters, 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. parameter settings Menu Adjustment range Default value Comment 01ZV (zero-capacity voltage) 0.0-100V 0.0V If the voltage is lower than this, the capacity will be automatically set to 0%. If you do not know the voltage characteristics of the battery pack (discharge voltage), do not set this value. 02OV (overvoltage alarm) 0.0-100V 100V When the voltage is higher than this, the voltage value will flash, and the will sound intermittently every 500 milliseconds. 03OC (over-current alarm) 0-Maximum value of range Maximum value of range Large value When the current is higher than this value, the current value flashes and the sounds intermittently every 500 milliseconds. 04 (low voltage alarm) 0.0-overvoltage value 0.0 When it is lower than this voltage, the voltage value flashes and the sounds intermittently every 500 milliseconds. 05LB (low capacity alarm) 0-100% 0% When the capacity is lower than this, the percentage and the battery symbol will flash, and the will sound intermittently every 500 milliseconds. 06HT (high temperature alarm) -9 to 99℃ 99℃ When the temperature is higher than this temperature, the temperature value flashes and the sounds intermittently every 500ms. (Standard products do not have this function) 07VC (Voltage value fine-tuning) When the displayed voltage value has deviation, it can be adjusted within a certain range. 08CC (fine adjustment of current value) When the displayed current value has deviation, it can be adjusted within a certain range. 09CZ (current zero calibration) The current is not 0 at no-load, and zero calibration is required. 10TC (fine adjustment of temperature value) When the displayed temperature value has deviation, it can be adjusted within a certain range. (Standard products do not have this function) 11CA (battery effective capacity) automatic test capacity, can be manually set under special cirstances 12FV (full capacity voltage) 0 When the voltage is higher than this, the capacity is automatically set to 100%, and this function only works in manual mode 13LK (menu lock) LOCK/UnLOCK LOCK Only the menu lock can be opened to modify the contents of menu it 01-12 (LOCK closes the menu lock/UnLOCK opens the menu lock) 14DF (restore default value) NO/YES NO Select YES, all current parameters are restored to factory settings. The menu content of item 01-12 can only be modified by opening the menu lock Note: Key operation method 1. The key operation is divided into long pre and short pre Long pre: pre and release the on for 3 seconds; Short pre: pre the on for 1 second to release; 2. on definition under normal measurement interface Long pre (setting key): enter the setting menu Short pre (setting key): display/turn off the backlight Long pre (down arrow): the capacity is set to zero Short pre (down key): View project mode (this is the manufacturer's view mode, customers can sk this) Long pre (up key): full capacity (used in special cases) Short pre (up key): release the alarm on definition in the menu setting interface Long pre (setting key): enter the item line Short pre (setting key): save the parameters and return to the previous menu Short pre (down arrow): select plus or minus digit Short pre (up key): modify the setting value Use FAQ 1. Do I need to set parameters 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 reversely, you can turn the r in reverse. 4. During the discharging proce 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 pa 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 aging 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 long time. I don't know how much AH the real capacity is. What should I do? Answer: After the battery is empty (empty), pre 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 long preing the up on (Note: long pre the up on without unplugging 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 pre and hold the up on to manually fill it up to display 100% (Note: long pre the up on without unplugging the charger) )
