Title: 34410A Relay clicking when in resistance mode only if i touch probes
Post by: Hrvoje_CRO on June 11, 2023, 12:14:19 pm
Hello dear people!

I have an issue/concern with my 2 34410A.

When in resistance mode, if i touch the probes (insulated parts, not the tips!), relay inside clicks over and over.

Please see a video, and sorry for potentially shaky video.

Thank you in advance!

There are a few spots on the resistance scale of the 34410A and also the 34411A when the relay clicks between rages, since this instrument can measure in the G-ohm range.

All my 34410A do the same, so no worries.

Hmm, strange is how i didn't noticed this behaviour before  |O .

Whatsoever, thank you a lot!

Oh yes, i almost forgot to mention, these instruments (34410A) are "buggy", they have a design flaw with autorange mode. Check this:

These instruments are not buggy at all.
Yes, this is a known small issue but easy to work around.
These multimeters are considered to be the best 6 1/2 digit DMM ever built. (At least my opinion)
They are just amazing when used correctly.

I must agree with you, this is why i did put buggy under quotation marks.
