Digital Voltage Meter - Accurate Coulomb Meter for Battery & Electrical Measurement | Perfect for DIY, Automotive & Home Electrical Testing

Feature:1. Automatically identify charging and discharging, and supports bidirectional current without changing the wiring direction.2. With power-off memory function, after power-off, the AH number before power-off can be memorized, which is convenient for observation and measurement.3. The meter has protection functions such as overvoltage, overcurrent, overpower, time limit, and overcharge.4. The display screen can be turned off manually or automatically after a certain period of time, which is quick and easy.5. Used for the measurement of voltage, current, charging capacity AH number, WH number, time and power, and the display information is comprehensive and clear.Specification:Item Type: Coulomb MeterMaterial: ABSType: Regulating ICCapacity Measurement Range: 0.001AH-65000.00AHEnergy Measurement Range: 0.00 kWh-99999.9 WHExternal Power Supply Voltage Range: 6-60VVoltage Measurement: 0.01V-120VInput Current Measurement Range: 0.1A-300A1.Voltage amplitude2.

ButtonHow to Use: When in use, first use the "BAT" terminal connected to the power supply, the positive pole or the second battery line to charge the battery through the HALL round hole, and then check whether the jumper cap is in J3, the best to collect the battery is the "BAT" expansion board On the negative terminal plug, independent power supply (12v-60v), live.Picture 1 is a non-relay power connection mode.When in use, the "Bat" terminal is first connected to the power source, next to the line where the battery is connected to the posit
