Just perfect. I checked the voltage readings against those of my very trusted multimeter ANENG 8002 (bought also from Banggood) and the difference in the range 1.2 – 33 Volts was less than 20 mV. Then, I checked both the voltage and the current readings against those of my RIDEN RD6006 power supply, and the measurements were almost identical (see photos).
So, I have already placed another two of these in my shopping cart. Whenever you find something like this instrument, you buy some extra to keep them in stock. Most combined volt/ampere meters go up to 30 – 33 Volts, while this one goes up to 100 Volts. And it is both accurate (shows the correct value of the voltage / current measured) and precise (value presented with 4 digits in total, and up to 3 decimals depending on the measured value). Thank you, Banggood.
