On this lazy new year, I do a comparison between some of my old cheap meter (for Capacitance and Multimeter) and my new well know brand, Sanwa.
I finish some measurement for Capacitor and Resistor. It seems even the old cheap meter (cost <US$10) could measure very well compared with my expensive Sanwa (rated at 0.08% accuracy, cost >US$100). But for some special purpose, especially very small value measurement, the more expensive meter would do it better and more accurate. If you don’t mind with the “very standard” (more polite word for “cheap”) build quality, rarely measure small value item, and don’t need extra digit accuracy, then you can go with cheaper meter.
I compare 3 meters here. One is multipurpose meter, Sanwa PC510. High tech meter from Japan brand, Sanwa. Claims 0.08% accuracy, AC True RMS, and capable of testing Capacitance and Temperature (beside a standard AVO function of a Multimeter). This meter cost around US$ 150. The others are two my old meter. One is Heles UX35 (a standard AVO meter, cost around US$ 5) and the other is China brand Capacitance Meter CM8601A+ (up to 20.000uF, Capacitance meter only, cost less than US$ 8).
As the subject, I pick Audio Note Copper Foil Mylar-In-Oil Capacitor (default value at 0.47uF) and three value of 12W Mills Resistor (3R9, 22R, and 22K).
The photo below will speak by themselves.
