A look at the Uni-T UT210E

[Filippo52]

Thanks for the advice, but I think it's safer to remove the batteries if you don't want to change the type.
Vapours are also the most treacherous, and if you let gravity do its work, you need to make sure the holes connecting to the inside of the device aren't at the top.
For me, the corrosion of the contacts cost me the most I could do: replacing the small metal pieces available for sale. However, the fumes had destroyed the tracks and contacts inside, especially the delicate ones on the contact displays. I managed to get the battery compartment working as good as new, but the device would still show strange signs of loose contacts and resets without cause, until it completely died.

i just use eneloops,
nickel-metal hydride.
the 1.2v doesnt seem to cause issues.
the only thing you notice is the backlight is not as bright.

Do you mean rechargeable AAA batteries?

Which is fine if it works for you. Thing with classic NiMH is, they have a relatively high self discharge.

Maybe they improved the technology, but the self-discharge may be higher then the actual use by the multi-meter.
Meaning I would expect you have an empty device every two months, regardless on whether you used it.

loops dont self-discharge.
atleast not at a noticeable rate, they are rated for storage for over a year with negligable loss.

I wish UNI-T would make a "2.0" version of the UT210E using a slightly larger mould, standard display orientation (a bigger one would be better), better backlight and upgraded their rubber finish on the sides/selector. Mine's already deteriorating without much use or exposure to weird chemicals

Hi. My clamp meter uses a 24C08C chip. Which chip should I select in the CH341A programmer so that the resulting .bin file is accepted by the UT210E firmware editing site? Can I safely select 24C02 instead of 24C08 in the CH341A programmer?

I also have a UT-210-E with a 24C08C EPROM and have always worked with 1K binary images and always set the correct size in the programmer.
Keep in mind that the first 256 B are the same, and you can use a simple binary editing program like HxD to convert the size of a 24C02 to a 24C08 by simply cutting and then overlapping.

Be careful, the remaining part must not be changed, otherwise the clamp of new type will lock when starting. And be careful when converting from 24C02 to 24C08 and overlapping, do not simply adding, otherwise the editing program will overwrite the space after 1K.
