I originally bought this for DC current measurement on home electronics projects. These are relatively low current circuits which when measured on this meter do not measure accurately enough. When measuring a steady 200mA 12v DC supply to a circuit, this meter was measuring between 200 & 330mA even when using the "zero" button on the meter. On higher current circuits, for example, 12v 5amp the meter was reading 5.1amps so still out by about 100mA but at this current, this is not as important. I compared this to the supply and an inline meter which were both within about 1-2mA.
So would I buy or recommend this meter, well no I wouldn't buy it because it is not accurate enough for my uses, it may be suitable for higher current applications.
It would be useful if someone with a better quality clamp meter could do a comparison.
Note I also tested the DC voltage via the cables and temperature via the included probe, both appeared to be accurate.
