Hey community,
So, during my time on this forum and as a viewer of Dave's content I have seen a lot of complaining about the 'quality' of lower priced DMMs, so as i own two lower priced multimeters I decided to open them up and have a look. Well actually, the original reason for opening these was to see if I could re-calibrate them, but anywho...
The first i opened was a ISO-tech IDM 72, and to be honest: It wasn't good quality, but way better than expected. (See attached picture)
Although the fuse wasn't in its own compartment, it was indeed pretty decent, compared to the other DMMs. Besides that, it was pretty neat, and seemed well designed. Some cables have even heat shrink attached.
The second DMM was a TE.Electronic MS8264, it seemed really well designed as well, taking price point into account, although i couldn't locate the fuse, hmmm......
The input terminals were attached well to the PCB, and it even had a shunt resistor!
Both PCBs were neatly laid out, and the components used seemed 'good quality' and the manufacturing showed no 'rushed stages' nor any errors.
So, although I completely agree on the fact that these are not 'perfect', they are still pretty decent, compared to what people normally say about these lower priced DMMs. Although i highly doubt that they are CAT III rated.
I would like to know what you people think about these? Because I would say that they are good enough for the average hobbyist and maker for taking quantitative measurements? Or is it just me who miss-judges these, and has way to less experience in the field to argue/comment on this?
