    It's hard for me to read and comprehend the Amazon listings. What I need most of all is an accurate Voltage reading. Everything else is stuff I don't need right now.

    Is there something more accurate than the UT61E?

    I also found these:

    BK Precision 2708B It can measure Voltage in mV
    Fluke 101 It alleges it can measure Voltage to 0.001v. In the Q&A section of the Fluke 115 listing on amazon,. a user said this one would be better for use in "troubleshooting" computers.

    I've been complaining for myself as I would also like temperature reading as well as high DCV accuracy

    The 101 has worse accuracy and the other does not have anything specified in there…

    But the new UNI-T UT2003/2004 seem to have even betetr accuracy than UT61E. They are for +- the same price and measure more things. Seems that my meter is cheap spin-off of these With terrible quality to say…

    Or you can get the bench UT802 with nice accuracy too.

    I went to the B&K site and DL'd their PDF's to get the specs.

    Could've as well post it here and save ppl the time searching it, whaddaya think?

    Its +-1% +2, still worse. TrueRMS, yeah, but you don't need that here.

    Do you know of a better DMM? OCCT reports Vcore as 1.21v. My MB reports current Vcore as 1.212v. But they are both operating from the same sensor. If is it systematically off by 0.1v (0,1v), then the actual Vcore could be anywhere between 1.11 (1.112) to 1.31 (1.312) Volts.

    Still, approximately
    An 0.1v error would be a 10% error.
    An 0.01v error would be a 1% error.
    An 0.001v error would be a 0.1% error.

    How well Do DMM's discriminate between Voltages at the 1-1.5v range?

    If you were to buy a DMM, which would you get? And what would its accuracy be at 1 to 1.5v?

    And temperature? I did not know they measured that.
    0.1% not 0.5% bro.

    Many DMMs measure temperature.

    How much accuracy do you need at 0.1%? ... 0.1% of 2V is 0.2mV.. Unless you want a U1272A of course.
