50A 100A 200A 400A STN LCD Hall Coulomb Meter Counter Voltage Current Capacity Power Indicator Display Battery Monitor For Car Link to the application. http://www.wooliis.com/upload/WBMS_1.0.4.apk GXQC0289-002 Mobile phone APP connection step-by-step instructions (Note: no need to enter the password pairing inside the Bluetooth list of the mobile phone) (1) Turn on the mobile phone GPS positioning, also assign the authority to WBMS. (2) Turn on the Bluetooth of your mobile phone, and assign the authority to WBMS as well. (3) In the permission management, find WBM software, and click "Nearby devices" permission to allow. (4) Open the mobile phone APP, click "Search" in the setting page, find "WBMS" device name, click to connect. After connecting, you only need to set the "rated capacity" and "full voltage" and then fully charge it once.

Product Selling Points: 1. Use high quality material, durable. 2. Low voltage alarm, high voltage alarm, over current alarm, low capacity alarm. 3. Full screen can display all the data, more intuitive 4. Hall induction non-destructive measurement, wiring is super simple 5. Simple and convenient to use

Parameter: Current measurement range: 50A/100A/200A/400A (optional) Supply voltage range: DC5-120V Voltage measurement voltage: DC0-300V Voltage resolution: 0.1V Capacity Measurement Range: 0-999AH (Note: 0-2000AH can be reached when only the percentage is displayed) Power measurement range: 0~999KW Power Measurement Range: 0~999KWH Meter Measurement Error: + -1% Refresh speed: 0.5S to refresh the display information once Temperature measurement range: -50 °C~125 °C Installation Slotting Dimension: Slotting Dimension: 76. 0mm * 40. 5mm (20mm in sensor threading hole diameter) Operating current: backlight on: 25MA, backlight off: 9MA (total power 0.3W, different voltage and current)

Function introduction: 1.Measure the battery remaining power percentage % and remaining power AH number. 2.Measure DC positive and negative bi-directional current size. Measure DC voltage size. 3.Measure DC positive and negative power size. 4. Measure the cumulative power size in both positive and negative DC directions. 5. Over-voltage alarm function, alarm voltage size parameters can be set by yourself. (Alarm sound, and alarm output control CN2) 6. Low voltage alarm function, the alarm voltage size parameter can be set by yourself. (Alarm sound, and alarm output control CN2) 7. Over-current alarm function, the alarm current size parameter can be set by yourself. (Alarm sound, and alarm output control CN2) 8. Battery remaining power low alarm function, the power icon will keep flashing, prompting the user to charge. (Alarm sound, and alarm output control CN2) 9. Battery over-temperature alarm function, the alarm temperature size can be set by yourself. (Alarm sound, and alarm output control CN1, can be used to control the battery cooling fan. Note: All control output signals are 10MA weak signals, drive the device requires customers to amplify their own external amplifier circuit amplified for control). 10. Power-down data saving function. 11. Using Hall sensor isolated measurement, safe and reliable, wiring installation is very simple and convenient. Note: Please do not interchange sensors to use!!!!
