It is a nice instrument. Shows both positive and negative current flow (which not many ammeters do), it is accurate (more than what the average amateur/hobbyist needs), the assembly instructions are good, and its price is more than nice. Its only drawback is that it needs a 5 Volt power supply, which is not easy to get from batteries. So, I decided to put it in a box, together with a regulated power supply (9 Volts battery + 7805 voltage regulator) and a switch. There are three ways to feed the current under measurement 1. Through two bare cables (in – out) 2. Through two receptacles for banana plugs (in – out) 3. Through two receptacles (in – out) for standard 2.1 mm DC power plugs (barrel type), so that you can check any power supply equipped with such a plug without having to cut the cables. I checked the ammeter against my favorite multimeter (the ANENG 8002) and throughout the whole range 0-2A the difference is negligible. Just for your information, it took me about 2,5 hours to assemble the unit (including checking all the components and the LEDs) and about 5 hours to make the box. Overall impression: Excellent value for money, very useful instrument.
