Description
This is tiny and compact digital voltmeter with a red LED Display. The 0.28inch 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.
This voltmeter can be 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 voltage.
Installation Notes:
– Ensure measured voltage does not exceed 100V DC
– For best accuracy, connect power supply separately from measured voltage
– Reverse polarity protection included for power inputs
– Display remains visible in bright lighting conditions
Wiring Connection:
Red Wire (VCC): Connect to positive power (4.5-30V)
Black Wire (GND): Connect to ground/common negative
Yellow Wire (VIN): Connect to voltage being measured
