Mini 0.36 Digital Voltmeter DC 4.7-32V 2 Wires Voltage Panel Meter LED Display – Red

This Mini 0.36 Digital Voltmeter DC 4.7-32V 2 Wires Voltage Panel Meter LED Display is designed explicitly for Vehicles Motor. This DC voltmeter is defined as one of the prominent devices used by an electronics technician.  It is a perfect tool for most applications and consumes less than 30mA from the target voltage source to power itself. The  2 wires on the panel meter display module hook up to the target voltage point. And measure the voltage reading on the 3 digits seven segment display.

This is highly accurate and compact-sized digital voltmeter comes with an  LED Display. In this module, the voltmeter uses 0.36-inch digital tube display, with a super small volume. To achieve the best measurement precision, voltage is measured according to the different automatic moving positions of the decimal point. During the connection, the red wire is to connect to the positive pole, and the black wire is to connect to the negative pole. As the module features reverse polarity protection, there is no need to worry if there exists any mismatch while connecting.

This voltmeter doesn’t need external drive working power, it can work with measuring voltage, the working voltage’s range is 4.5-30V. In order to obtain high measurement accuracy, the position of decimal points moved automatically according to the different measuring voltages. When the measured voltage is below 10V, it displays two places after the decimal point. Whereas when it measures above 10V, it will display one place after the decimal point.

This voltmeter is widely used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltages. As the 30V is the maximum operating limited voltage of voltmeter’s, during operating please leave enough margin. This avoids the voltmeter’s permanent damage due to an electrical spark, power supply ripple, or other too high abrupt change of voltage.
