Two Wire Voltmeter Red Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!!
The red wire is connected to the positive pole, the black wire is connected to the negative pole. While measuring the supply voltage of another source make sure that the negative pole is joined common. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection.
To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltages. When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point.
This voltmeter can be used to measure the storage battery’s voltage up to 100Volts in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other DC voltages. This voltmeter can operate on versatile 4.5V to 30VDC range is the voltmeter’s maximum operating limited voltage, please leave enough margin (i.e. do not reach up to the last limit ) when working, to avoid the voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.
Note:
