Hi,
I have done a current measurement using three Pro'sKit MT-1707 DMMs. As shown in the attachment, the second DMM has different reading compared to the other two DMMs by 0.03 A (approximately 1.5%).
Can I calibrate the MT-1707 myself with the help of the 6.5 digit DMM? Or, in other words, can end user calibrate MT-1707 own self?

Open the case and check if you have some trim pots in it, if there is, before touching them, take measurements of them just in case, note the values on a sheet.
Try to find the Meter chip specs in it, hoping its not a black blob ....
