0.56inch 0-100V Three Wire LED Display Digital DC Voltmeter-RED
Introducing the all-new, compact digital voltmeter with a red LED display. This 0.56-inch, 0-100V three-wire DC voltmeter red panel is user-friendly, requiring only a few minutes to set up. Simply connect the wires directly to the power source you wish to measure, and watch the LED indicator come to life!
Connect 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 intended source or another source across which voltage measurement is desired. Ensure that the negative terminal is commonly connected when measuring the supply voltage from a different source. There’s no cause for concern if the wires are connected incorrectly; the electrical circuit won’t short out due to its reverse polarity protection feature.
This voltmeter features an automatic decimal point adjustment for optimal measurement precision. It displays two decimal places for voltages below 10V and one decimal place for voltages above 10V.
It is ideal for measuring battery voltages in motorcycles and cars, capable of handling up to 100 volts, thus offering insights into the battery’s condition. It is also appropriate for other DC voltage measurements.
With an operational range of 4.5V to 30VDC, it is crucial to remember that the voltmeter’s maximum operating voltage is 30VDC. To avoid damage from electrical sparks, power supply fluctuations, or sudden voltage changes, it is recommended to stay within a safe margin below this limit.
The bright and clear LED display is designed to measure DC voltages ranging 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:Â 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 voltageÂ
CASE 2: If you have to measure the voltage of another source then with a separate power supply for Voltmeter:
