0.56inch 0-100V Three Wire LED Display Digital DC Voltmeter-BLUE
We are excited to present the newest member of our product family: the sleek and compact Digital Voltmeter with a BLUE LED Display. The 0.56-inch 0-100V Three Wire DC Voltmeter BLUE Panel is designed for effortless installation, taking only minutes to set up. Just connect the wires to your desired measurement source, and watch the LED illuminate.
Attach the Red wire to the positive terminal, the Black wire to the negative terminal, and the Yellow/White wire to the positive terminal of the measurement source or a different source. When measuring across a separate source, make sure the negative terminal is shared. Additionally, the integrated reverse polarity protection guarantees safety against incorrect connections.
The voltmeter’s precision is enhanced by its ability to automatically shift the decimal point according to the voltage detected. It shows voltages under 10V with two decimal places and voltages over 10V with one decimal place for clear readability.
Ideal for monitoring storage battery voltages in motorcycles and cars up to 100 volts, this voltmeter is indispensable for assessing battery health. It is also effective for other DC voltage measurements.
It operates within a broad range of 4.5V to 30VDC. Note that the maximum voltage for safe operation is 30VDC. To avoid damage from electrical surges, power fluctuations, or sudden voltage spikes, it is advised to operate below this maximum threshold.
Equipped with a vividly bright LED Display, this voltmeter stands ready to deliver precise DC voltage measurements from 0V to 100V.
Note:
- Consider 1V voltage drop at voltmeter itself, as we observed it at robulabs while testing this Voltmeter.
- Product Image may vary in terms of colour 3rd Wire and PCB or PCB-layout as per the version update from the manufacturer.
Connections:
- Red Wire: Positive of the Power supply
- Black Wire: Negative of the Power supply and also used as the negative of the measurement voltage source
- Yellow/White/Blue: Positive of the measurement voltage source.
With this Voltmeter Measurement can be done in two different scenarios observe the connection illustration accordingly:
CASE 1: If you have only one power source to give Power as well as to measure the voltage
CASE 2: If you have to measure the voltage of another source then with a separate power supply for Voltmeter:

Frequently Asked Questions
1. What is the minimum voltage required for accurate readings?
The display powers on from about 3 V DC, but accurate measurement begins above 3.6 V; below that the digits may light but readings aren’t guaranteed.
2. How do I wire the three leads correctly?
Connect the red lead to your DC positive supply (3–100 V), black to the common negative, and yellow (or white) to the voltage point you wish to measure. Do not swap measurement and power wires.
3. What is the unit’s accuracy and update rate?
This voltmeter offers ±0.1 V accuracy with a refresh speed of approximately 200 milliseconds per update, making it suitable for most DC monitoring applications.
