This is a simple 3-digit LCD display of voltage.

To use it, first hookup the power voltage (between 3.3 and 30 volts) to the red (+) and black wires, with black as ground (-).

Then, hookup your input voltage that you wish to measure to the yellow/white and black wires. If you wish to measure the voltage that is powering the device, simply twist the red and yellow/white leads together.

Pinout:

• Black: Shared Ground (-)
• Red: Power (+)
• Yellow/White: Input (+)

Specifications:

• Measured voltage range: 0 - 99.9 VDC
• Power voltage range: 3.3 - 30 VDC
• 1.80 inches (45.91mm) wide, by 1.1 inches (28.08mm) tall, by 0.670 inches (17.02mm). These are rough measurements.
• Voltage Accuracy: within about 300 millivolts.

NOTE: Display color may vary depending on what our Chinese supplier sends us. Some may also have a calibration pot. Some may not. If you have a specific requirement for blue, please call us before placing your order to verify stock. 425-641-7275 (press 1) ALSO NOTE: These are NOT super precision instruments. They will usually be *about* 300 millivolts off either plus or minus. If thats too much, you may want to ask us for more precision options.
