DMM other than Flukes that chirp on diode/transistor test?
« on: April 10, 2021, 01:01:01 pm »
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.

Uni-t UT161E

Open circuit voltage: About 3V
For normal diodes, the buzzer will beep once.
For short circuit, the buzzer will beep for a long time.

At 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

According to the manual, the 161B/D or 61B/D+ also have the feature.

Keysight U1273A and U1282A (most probably their brethren U1271A/1272A and U1281A do that as well)

My recommendation would be to ask the store and they will tell you its capabilities.

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.

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

Yes, 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.

Good Morning JayJr.,  I'm a bit late to the dance, but I just now
checked my Uni-T UT890C and it beeps on diode test.  And only $22 on Amazon.   :-/O

Does the EEVblog BM235 have this feature?

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!

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).

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.

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.

Do we have list for DMM which beeps on diode mode ?

 Don't assume that all Fluke models have Diode Test beeps. My 18B+ doesn't. Annoying!

My UT61D+ has that feature. It can do long beep for shorts (0 volts) and short beep for as low as 150mV (enough for most schottky diodes).

Brymen BM879 has this feature. The function is called BeepLit™ diode test.
Perhaps you will find it in BM785, BM786.

How innovative :-DD

User 2N3055 confirmed that it's present on the BN785 and 786 in addition to 789 almost two years ago before this topic was revived from the dead:

Since this defunct thread was revamped...  ::)

The AstroAI M6K0R also issues a short beep from 0.0V to 1.0V. This meter is also known as the Kaiweets HT118A.
