We did a calibration of this this mini clam meter. In AC V or DC V mode, the measuring unit is more accurate than display can show. We used a precision calibrator for this purpose. Calibrator: 1.000000V Meter: 1.000V In voltage mode, there is no deviance from calibrator. Resistance: At lower resistances, the measured values are exactly the same with calibrator values, like in voltage mode. From 20 kOhm, a very little deviance appears. Calibrator 20kOhm Meter: 20.01 kOhm Current: Of course, clamp metering method of current is not so accurate than direct measurement. This little instrument shows about 1,4-1,6% less than nominal value. But you have to set zero before DC current metering, because zero is moving quite fast. So at 20Amp range, 20A current, clampmeter show about 19.85amps. At 2A range with 100mA DC, it shows 90 - 97mA. The AC and DC errors were same both voltage and current measurement.
