Description
The digital voltmeter is designed to measure the voltage of an electrical circuit. A feature of the module is the small size of its indication. This digital voltmeter can be used in the power supply, on-board computer of the car and other devices that need visualization of voltage values. It can also be used to control the voltage of chargers.
The current voltage value is displayed on a seven-segment display. The measured voltage range is from 0 to 30 V. The measurement error of the device is ±1%.
The meter has 3 wires:
Red wire: 4 - 30 V digital voltmeter power supply
Black wire: "ground"
White wire: external power supply voltage measurement 0 - 30 V
The digital voltmeter is already calibrated. Additional calibration of the digital voltmeter is carried out using a trimmer resistor, which is located on the reverse side of the board.
