Good quality!

Reviewer: from COLTON, SD USA

This meter simplifies assembly for a low-cost power supply, or entry level battery monitor. The volt scale is accurate with a 15K resistor. For the ammeter shunt (3 amp=.0185ohm) I used scrap stainless 16 gauge weld rod, ~45mm long. The stainless rod inside a spent windshield wiper blade was fine too. Of course, the scale can make 0-30volts, or 30ma or 150ma or...? Use a good DPDT switch to flip between Volts and Amps, meter at center poles.
