Digital Voltmeter Ammeter 30V 10A Red and Blue

Sparkfun's Digital Voltmeter Ammeter 30V 10A Red and Blue is a DC current/volt meter that provides constant monitoring for battery-backed systems. With its ability to measure up to 30V and 10A, and using approximately 15mA quiescent current, it's an ideal tool for diagnosing system issues quickly by checking the overall system voltage. Furthermore, it helps in calculating run times based on instantaneous current consumption rates, making it a useful addition to any electrical setup.

The digital voltmeter ammeter comes pre-calibrated but also includes a small trimpot on the back side for further calibration after installation. This feature ensures accurate readings, contributing to the overall reliability of the device.

The wiring diagram for the voltmeter ammeter is straightforward. It includes a 2-pin wiring harness for the ammeter, which is typically wired into the current return path to the battery or ground. Additionally, a 3-pin wiring harness is provided for the voltmeter. The black wire on the 3-pin harness is internally connected to the ammeter and can be left not connected (NC) or connected to the ground. For the device to function properly and display the correct readings, the red wire of the ammeter should be attached to the system and the black wire should be connected to the ground.
