Good day, EEV bloggers!
New member here. I'm a former EE but am currently writing "boring business software" as someone said well on this forum. So, already being an amateur, I felt that I needed a good new reliable tool.
I read all these battles here on the forum, comparing one in a yellow holster to another in a red one. Yelow or red? Hmm... good question. And I'm already have one DMM in a red which is Uni-T UT71E. Which sometimes has glitches (smth. with selector contacts?), too loud beeper, fluctuating digits, terrible continuity mode, etc. So I decided to buy a more reliable one.
The things I considered for new DMM is:
- long-term stability (as I believe I can't afford going to certification labs every xx years)
- reputation/brand (well I never had anything from the top echelon before)
- and perfect internal design (look at that 87v board and the number of elements - the simplicity is a key; "beautiful" as Dave likes to say)
So finally I selected to buy the yellow one. It will be my only top grade DMM on the bench.
I think the number of digits is not that important to me and can be distracting. While less crowded dial is a plus.
The phrase on the Dave's blog I love the most is - "don't turn it on, take it apart!!!". Cool! This is exactly what I planned to do.
Of course I checked if it works correctly before doing that. I have also compared and recorded the readings in all ranges with the Uni-T (I can share results). So that after assembly I can make sure that the readings are the same and that teardown does not affected the accuracy.
Some teardown justification: I wanted to see the overall build quality, to check if shield is not bended (I've seen pictures on this forum) and to check the fuses brand.
So, here are some photos of the internals for those who would like to check the revision number and to compare with previous versions.
Bought it from the well-known German online store W****.
