In terms of measurement accuracy, there is nothing to complain about this multimeter. In our tests of other cheap multimeters, there is always a measurement range we are not so satisfied with. That is not the case with this 189C. You can be confident that any measurements you make with this meter will produce a result that is more than accurate enough for the average hobbyist. The input resistance of 10 MΩ is excellent and so is the burden voltage of only 100 mV at 5 A. It is worth noting that the 189C also measures small capacitors satisfactorily, which is not the case with all cheap multimeters. About the uniqueness of this meter, its operation with the ‘Smart Rotary Knob’ praised by the manufacturer, we dare not judge. If you are used to multimeters with rotary knobs, switching to operating a meter with such a large, thumb-operated ring will take some getting used to. Whether you choose to do so is a matter of personal preference. But after some fiddling with the device, adjusting with the dial is very intuitive and easy. This is undoubtedly also due to the fact that after a while you know where the various measurement quantities and ranges are located on the circle, so you no longer have to search.
Everything arrived correctly.
