- Connect the attached 1.25 terminal wire to the plug on the product backside.
- Connect the red wire to battery positive, the black wire to battery negative, make sure the contact i s firm.
- Power on the meter, it w i l l display battery capacity percentage, voltage and temperature.
- Click the ON/OFF button can t u r n off the meter. At turned-off status, click the ON/OFF button, it w i l l wake up the meter. If set delay turning off, after powered on, the meter w i l l automatically t u r n off when reach the set delay time.
- The 7 battery bars on the display, from right to left, indicate the battery remaining capacity from low to high.
- The displayed voltage value i s the detected voltage value 10-100V, no external power source required.
- The displayed percentage is the battery remaining capacity percentage.
- The temperature unit can switch between °C and °F. The detected temperature value i s the temperature of the meter.
- When the battery is connected to charger or high-current load for discharging, the displayed parameter w i l l fluctuate.
- The SET button on the meter backside can be used for setting and changing parameter.
- lf the meter i s not accurate enough for some special occasion, it can set the upper and lower limit of the battery capacity through Programming Mode 3– via
the SET button.
- At power-on status, long press SET button for 2 seconds, it will enter main menu as Figure-1:
- There are 6 sub-menus on the main menu: 1 – – , 2–, 3–, 4–, 5–, 6–.
- After entering main menu, click SET, the 6 sub-menus loops.
- Functions of the 6 sub-menus:
1–:Adjust the preset battery specification, L for Lithium
Battery, F for Lithium Iron Phosphate Battery, P for
Lead-acid Battery.
2–: Enable/Disable delay powering off, delay time range 10-120 seconds.
3–: Custom percentage upper/lower limit voltage.
4–: Low-voltage alarm ON/OFF ( n o t available) & alarm voltage setting (not available)
5–: Over temperature alarm ON/OFF (not available) & alarm temperature setting (not available), temperature unit ‘C/‘F setting.
6–: Voltage Calibration (requires a 20V standard stabilize voltage power source).
5 , Click ON/OFF button, choose the sub-menu to e n t e r. After
finish setting, l o n g press SET to exit.
6. All parameters are subject to the last save.
1–: Set Preset Battery Specification
- At this sub-menu, it can adjust the preset battery specification. The corresponding code of each battery specifications are as follow:
- L for Lithium Battery, the followed number is the series number.
- F for Lithium Iron Phosphate Battery, the followed number i s the series number.
- P for Lead-acid Battery, the followed number is the voltage value.
- e . g . L3 presents 3 series lithium battery, 4.2V*3S=12.6V
L7 presents 7 series lithium battery, 4.2V*7S=29.4V
F4 presents 4 series lithium-iron phosphate battery, 3.2V*4S=12.8V
F8 presents 8 series lithium-iron phosphate battery, 3.2V*8S=25.6V
P12V presents 12V lead-acid battery.
P48V presents 48V lead-acid battery.
Setting Steps:
Long press SET to enter sub-menu 1–, click ON/OFF button, screen displays L on the right side as Figure-2. Click SET to switch among L/F/P to choose the corresponding battery code, click ON/OFF button to enter. If choose L/F, click SET button to adjust battery series number; i f choose P, click SET button to adjust voltage. After finish adjusting battery code, long press ON/OFF button to save and go back to the las t interface, long press SET to exit and go back to main working
interface.
Note: If the battery code doesn’t match with the applied battery specification, the percentage value will be inaccurate, and only the voltage value and temperature will be accurate.
2–: Delay Powering Off Enable/Disable & Delay Time Setting
- At t h i s sub-menu, it can enable/disable delay powering off function and set delay time.
- After entering sub-menu 2–, screen displays as Figure-3.
- Left side i s delay function ON/OFF indicator. ON = Delay Enabled, OFF = Delay Disabled.
- Right side is delay time. Available delay time to choose from is 10s/30s/60s/120s.
Setting Steps:
After entering sub-menu 2–, click SET to switch the parameter.Click ON/OFF button to carry bit longpress ON/OFF button to save. If no other parameters need to
beset , long press SET to exit.
Note: If delay function i s enabled, when reaches the set delay time, the meter w i l l automatically power off and enter ultra-low-power status.
3–: Custom Upper/Lower Limit Voltage of Percentage (Not recommended for non-professionals)
@ At t h i s sub-menu, it can adjust the upper/lower voltage of the percentage. After adjusting, the meter can be used for Ni-MH battery,fuel battery, e t c .
e After entering sub-menu 3–, screen displays as Figure-4.
e Left side i s corresponding voltage of battery capacity 0%, low battery voltage
Right side is corresponding voltage o f battery capacity 100%, full battery voltage.
Setting Steps:
After entering sub-menu 3–, click SET to adjust the set voltage; click ON/OFF button to carry bitlong press ON/OFF button to save. If no other parameters need to be set, long press SET to exit.
Note:
1. Ifthe left side value i s set to be 10V, right side value i s set to be 20V, then the percentage w i l l calculate according to range of 10V-20V.
2. The upper and lower l i m i t cannot exceed the working voltage. lf the upper and lower limit are the same or difference <1V, data won’t be saved.
- Atthis sub-menu, it can calibrate the meter. Displays as Figure-5.
- Before entering calibration interface, please provide accurate 20V working power for the meter.
- To avoid misoperation, to enter calibration mode, it needs to long press ON/OFF button at 6– status; after entering, it will be automatically calibrated. If the provided power is beyond 19-21V, data won’t be saved.
Note: Before entering calibration interface, make sure a 20V accurate power source is provided, otherwise the error will be larger. After entering calibration interface, it will automatically calibrate; after finish calibration, it will automatically exit to the working interface.
- Noresponse after powered on:
Check if the wiring positive and negative connected correctly and tightly . (Measure the meter input with a multimeter to check if there is voltage (10-100V) and check the polarity.)
2. Displays accurate voltage and temperature but inaccurate battery capacity:
Make sure the preset battery code matches with the applied battery type. If not matches, set following the above instruction.
