Calibrating and hacking the UNI-T UT210E clamp meter

My UT210E clamp meter was serioulsy out of calibration in the current ranges. This video shows how I calibrated it and applied one of the many hacks available for the UT210E, to change it from 2000-count to 6000-count. This means for example that in the 2A range the maximum value that could be measured was 2.2A but with the change it can now go up to 6.2A. Same is true for volts, ohms.. Especially in AC volts measuring mains 240VAC, you now have an extra digit resolution!

BTW, I could not get the CAL menu to work. If anyone has good(!) information how this is supposed to work, I'm happy to give it another try (now that I have a backup of the CAL data)
