UNI-T UT61E Multimeter teardown photos.

Found a son of someone who go to electronic school and has access to 6.5 digit multimeter...

If your UT61E is recent, and you are considering using a (calibration-wise) 4yr old Fluke 79III to calibrate your new UT61E -- that (to me at least) means you are not trusting the UT61E being within spec. Why not get a DMM-Check (plus) from VoltageStandard.com. Now you have reasonably good and absolutely fresh references to go by.
I did not take a count, but based on memory: I have seen (4+) folks here posted that their UT61E (as delivered) are in spec, and only one post I can recall saying the 61E being slightly off-spec on delivery. If you decide not to go with DMM-Check, it sounds to me a good bet to just trust the 61E to be the more accurate of the bunch.
gatos:
At Lightages and Monkeh: I agree, but I can not explain the measurement on 1.5V battery and the difference with the 12V.
Any ideas?
At T4P: Don't you think that I have to tweak up the SUMMIT, in accordance with the other three (at AC voltage-grid outlet)?
As I said before, I would like to buy a DMMcheck plus (start saving money-remember we have crisis in Greece!).

Resistor network.
Lightages:
As Monkeh said, the internal resistor network that is used to divide might be faulty. But this is getting way off topic and we are polluting this thread. Please start another thread if you want to discuss adjustment and calibration of anything other than a UT61E.
