content: Anyone know of any other meters that chirp/beep while testing a good diode? Maybe small but I find this to be almost an essential feature. Looking around the $100 mark.

content: Quote from: Wytnucls on April 10, 2021, 02:23:48 pmAt first I thought you were crazy, I have a 61E and it doesn't do this. Then I noticed you said 161E. Thanks for the recommendation. Do you think the new UT61B+ will support that as well? It's just a 6000 count vs 22000

content: I haven't heard a diode-test beep feature for decades. What's a good diode? Vf varies between Schottky, Germanium, Silicon.I see old Protek 506 using this criteria to display pass/fail, it's wrong for Schottky.

content: The Keysights do a short beep between 0.2V and 0.7V. Anything below 0.1V beeps continuously. Between 0.1 and 0.2V it does not produce a beep.But I missed the OP's requirement of ~$100

content: Quote from: rsjsouza on April 11, 2021, 12:36:18 amYes, pretty much this. Just don't want to have to look up when testing for a good diode junction. I have the Uni-T UT161B on order from Amazon. If it doesn't have this feature I can easily return it but as someone said above, it appears the B supports this as well.

content: I think I might have a go at making an app or script for my DMM6500 to do this, as I really like the Fluke method of a short beep for a diode, long for a short. The default diode test mode has adjustable threshold levels etc but has a continuous beep (of an oddly low frequency, but again I think this can be set in the app/script). Not <$100 though!

content: I ended up grabbing a Uni-T UT161B on Amazon on sale for $60 shipped. It does in fact have a diode chirp when testing a good junction, and also has a continuous beep for shorted. Continuity is fast but as @eevblog reported in his video of the UT161E+ the stupid visual LED for continuity is not tied to the buzzer but to the display. (I agree Dave, big fail).

content: The old UT71A can also beep repetitively for a voltage, which falls below a threshold set by the user, in diode mode.It still sells today for about 120 USD.

content: This UT161B is rather unimpressive in a lot of other aspects. The diode chirp is exactly what I wanted but man the autoranging is so slow and the release lag of the continuity is so annoying. Maybe I'm being too picky. Otherwise on paper is such a good meter. They even have a real beefy HRC fuse and much better input protection now. I wonder with bi-directional communication built in now if it will be "hackable" or firmware upgrade-able.
