While a DMM is great for a quick check, a panel mount current and volt meter is handy when you need to constantly monitor a system. Battery backed systems can be quickly diagnosed by checking the overall system voltage; run times can be calculated based on the instantaneous current consumption rates. For all those times and more, it's just super handy to have a meter available.

This digital combination DC current/volt meter measures up to 30V and 10A using approximately 15mA quiescent current. All units come pre-calibrated but can be further calibrated once installed using small trimpot on the back side of the device.

The wiring diagram shows a normal hookup. The thicker 2-pin wiring harness is for the ammeter and is normally wired into the current return path to the battery or ground. The thinner 3-pin wiring harness if for the voltmeter. The black wire on the 3-pin harness is internally connected to the ammeter and can be left NC (not connected) or to ground. The Red wire of the ammeter should be attached to the system and the Black wire of the ammeter should be connected to ground otherwise the system will work fine, but the meter will display 0.00 as it cannot display negative values.
