0.56inch 0-100V Three Wire LED Display Digital DC Voltmeter-RED
This is All new tiny and compact digital voltmeter with a RED LED Display. The 0.56inch 0-100V Three Wire DC 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 to connect to the positive pole, the black wire is to connect to negative pole and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage. 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.
This voltmeter is equipped with an automatic decimal point adjustment feature, ensuring optimal measurement accuracy. When measuring voltages below 10V, it displays two decimal places, while voltages above 10V are displayed with one decimal place.
Ideal for measuring battery voltages in motorcycles and cars, this voltmeter can handle up to 100 volts, providing users with insight into the battery’s status. Additionally, it’s suitable for measuring other DC voltages.
Operating within a versatile range of 4.5V to 30VDC, it’s important to note that the maximum operating voltage of the voltmeter is 30VDC. To prevent potential damage from electrical sparks, power supply ripple, or abrupt voltage changes, it’s advisable to maintain a margin below the maximum limit.
Very bight and decent LED Display is ready to measure the dc voltages in the range of 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:
