Review on Megaohmmeter digital CEM DT-5300B by Micha Borkowski ᠌

After four measurements, it stopped working, it was not suitable for repair, it was under repair for 7 months, after repair there was a large error of 2.1 ohms (CALIBRATION COULD NOT BE SUCCESSFUL) in a word (one-time) This is the same CEM but of the type for the domestic market of China, I have a lot of measuring devices from CEM, so it's better to buy a professional device.
