Feature: 1. The 2.4‑inch color screen, the font is larger and clearer, and the appearance is beautiful. Automatically recognize the current in both charging and discharging directions. 2. Using current x working time to calculate the capacity of charging and discharging is more accurate than calculating the remaining power by voltage. 3. The mobile phone APP can connect to the meter via wireless Bluetooth to view data and set parameters. The mobile phone APP can upgrade the firmware of the measurement module. 4. The mobile APP can view the real time curve and historical curve of voltage and current, and support historical data export. The shunt and screws are made of pure copper materials, and the power consumption is very low in standby mode. 5. The parameters of voltage, current and temperature can be calibrated by themselves. The display and measurement module are connected through a 3 meter telephone line, and the maximum length can be extended to 30 meters, which is more convenient for installation. Specification: Description: The KG-F series color screen wireless bluetooth battery coulomb meter is a professional instrument for monitoring battery power. It can also monitor the voltage, current, power, ambient temperature, and energy of the battery during charging and discharging. And display how long the battery can be fully charged in real time, how long can the remaining battery power be used. KG110F measuring current range is 0-100A, KG140F measuring current range is 0-400A, KG160F measuring current range is 0-600A; Lithium iron batteries and all other batteries with voltages of 0-120V can be used in the fully charged state. Specification: Model: KG110F, KG140F EN, KG160F (optional) Voltage measuring range (external power supply): 0-120V Voltage measuring range (self-supplied): 10-120V Voltage resolution: 0.01V Current measurement range: 0-100A, 0-400A, 0-600A (optional) Current resolution: 0.01A, 0.1A, 0.1A (optional) Relay: optional Temperature range: -20-120℃ AH range of measurement: 0-9999.99AH Bluetooth communication distance: 10m Voltage accuracy: ±2%+3 digits Current accuracy: ±5%+10 digits Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3mm measuring deviation due to manual measurement. . Package List: 1
