Backlight 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.

When 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 battery.
2. Connect the red wire to the positive pole of the power supply.
3 yellow wire to the positive pole of the battery
When the voltage range is DC5-90V, the red and yellow wires are connected in parallel to the positive pole of the battery. 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 use
1When the battery is discharging, Coulomb displays a positive current. When the battery is charging, Coulomb displays a negative current. If not, the sensor is in the wrong direction. Please reverse the sensor direction.
