3-Digit Display Panel Digital Meter / Ammeter - Black (DC 10A)

Pros: Small overall size with bright, clear 3 digit display. Includes connectors and short leads along with a built in shunt.

Cons: This product sorely needs some basic information provided along with it. The ammeter connection MUST be on the negative side of the load as the Ammeter output wire (black) is connected to the supply side 0DCV (black). Accuracy is fair but non linear. i.e it reads low 0-1A and high 7-9.9A

Other: It works and provides an inexpensive approximation of current which is good enough for many applications. It will not replace a good multi-meter.

Pros: Very good indicator of voltage. The size of the numbers is perfect to be placed on a dashboard. The making power at the same voltage to be measured. Very convenient! It is very easy to use, just connect the wires.

Cons: The error in the measurement was very large (more than 7%). I had to fix from within the instrument circuit.

Other: Nothing to add. Really is a great buy you will not regret making. It will be money well spent.
