Button Usage InstructionsBacklight control:In the standby display state, short press the " " key to turn on or off the screen backlight. The backlight state is automatically saved when the power is turned off.Clear current:In the standby display, press and hold the " " button for about three seconds to clear the current. (Note: the load must be no-load when clearing, otherwise it will be inaccurate)Clean electricity:In the standby display, press and hold the " " button for about three seconds to clear the power.1 “AH XXX.X” rated capacity setting menu.2 "FU XXX.X" full power automatic voltage compensation menuenvironment.3. “HU XXX.X” high pressure alarm setting menu.4 “LU XXX.X” low voltage alarm setting menu.5 “HA XXX.X” high current alarm setting menu.Current test range0-100A0-200A0-400ACurrent resolution0.1A0.1A0.2APower supply voltage rangeDC5-90VVoltage test rangeDC0-300VVoltage resolution0.1 voltCapacity test range0-999AHPower test range0-999 kW energy test site0-999 kWhPanel mounting dimensions76.0mm*39.5mmSensor hole diameter20 mmWorking currentWhen backlight is on: 10MA.When backlight is off: 4mA.The meter has three wires, as follows:1. Connect the black wire to the negative terminal of the .2. Connect the red wire to the positive pole of the power supply.3 yellow wire to the positive pole of the When the voltage range is DC5-90V, the red and yellow wires are connected in parallel to the positive pole of the . As shown below:When the measuring voltage range exceeds DC5-90V, another power supply should be found for the coulombmeter. As follows:7. Precautions for use1When the is discharging, Coulomb displays a positive current. When the is charging, Coulomb displays a negative current. If not, the sensor is in the wrong direction. Please reverse the sensor direction.1 * Sensor1 * 15cm sensor extension cable1 * 3p power cordBatteries Included: No: DC 0-300VDIY Supplies: Size: 80*42mmWorking temperature: -10℃-65℃Accuracy level: HighPower supply: DCDisplay Type: Numbers only
