UNI-T UT210E Problem

[HolidayBob]

Hi all,  I have a UT210E which I bought from Asia a few months back.  I have noticed that the AC/DC voltage it's way out.  All the other ranges OHMs, current etc are working spot on.  I have tried to do a re-calibration by holding down the Blue/Yellow buttons and switching on, it goes through and returns ERROR 0 which I assume is correct.  So my question is are there any trimmers inside the unit I can adjust to sort out the voltage problem?

I look forward to any help anyone can give.

Hi

Welcome to the EEVBlog forum.

There are no trimmer pots in the UT210E for calibration. The calibration is held in EEPROM.

Hi MosherIV, Sorry for the very late reply and thanks for the reply and welcome.  So if there is no way I can fix this easy looks like I will have to put up with it.  I just checked a voltage fro my bench power supply which is set to 9V DC, measured on the 210E it reads 11.78V dc!
