One suggestion: make an option that with key combination you can disable all system sounds except continuity beeper. And make it remember your choice... That is one thing I don't like about Brymens, you can disable it in power up, but you have to do it every.single.time....
Interesting... Does your Brymen beep like the cheap-o-meters that annoy me at every change of scale on the switch? Or is it only during recording/logging?

My BM857 is my quietest meter - pretty useful when I am doing something at the TV room with the missus watching some of their favourite shows. :-+

It doesn't beep  when you are rotating main switch, but it beeps on any keypress, and when in crest or min/max mode when it acquires  new extrema..... And it will remember operating modes but not this... grrrr..
You have to start it with Range button pressed and than it is quiet..

I checked, and it doesn't save it. Will request that!

I also just found that when beep is disabled it actually disables the continuity buzzer! I guess their idea there was that the flashing backlight visual alert was enough?
Have asked them if they can fix that.
I can't imagine that such  "continuity always beeps" isn't more useful than not.

Thanks for listening. 

I specifically asked that because i did try some meters that were "all or nothing" i.e. you either can have beep all the time or if you make i silent than it disables even continuity...
Brymen does it properly, but doesn't remember ...

This one is a Brymen and it disables the continuity.

LOL.
869S doesn't. I will try 525S when I get back to office...

EDIT: I tried and yes, 525S and 869S behave the same in regards to beeps.   If you start them with RANGE button pressed they beep only on continuity. Otherwise they are Mr. Beepalot.....

I see now. The BM857 is the same but you need to press the ~Hz button at power up.

Neither the BM857 - the continuity beep stays on.

I can't think of a single reason why you would want to turn off the continuity buzzer.

"Screen lights up" doesn't cut it because you have to take your eyes off the job and it might be in a very fiddly situation where you need to keep both eyes on the probes.

(or a very dangerous one...)

U1272A disables continuity buzzer :palm:
Still my fav handheld DMM though.

If it's within range of your peripheral vision, that's actually more sensitive to motion (changing light levels) than your central vision.

A good feature would be to have a variable audible tone following the measurents values,  that way you hear what you measure, no need to have your eyes on the meter,  that was very practical to follow some glitches, had this  on a Fieldpiece hd7x  meter and an Beckman Industrial / Wavetek hd160,  i miss that feature

They are seeing if they have the code space left to add the features. They must be close to the edge I guess.

Keysight's U1273A also has this. I personally don't use it (I like quieteness)

Same here. I would like if somebody would think of loudness control for meters. Most meters have sound volume set for work on industrial machines....
That is too loud for office/lab work....At least for me... Also tone is usually quite annoying (probably on purpose). A softer, more gentle tone for quiet environments would be nice...

Yes and perhaps something not as startling as a loud beep, when you least expect it, stabbing yourself in recoil, with your sharp probes. A little tune would solve the problem, like the kumbaya song for example.

I think the keysight/agilents do that, too.

:-DD :-DD :-DD
To me the absolutely worst offender is the U1282A. It screams for absolutely everything, let it be the over sensitive NCV or the A/mA/uA jack alerts, to the point of me actually avoiding it at work (I work on a cubicle and neighbours are usually quiet). That despite having a very sensible beeping setting that disables the power on beep and its frequency can be set.

I have absolutely no idea why Keysight left such unconfigurable loud beep in an otherwise very capable handheld meter.

Thats why  all our toughts, brain storming and feedbacks could help dave make a good meter ...  and  this one could evolve in the future with an added wifi or bluetooth connection,  even an optical one would be nice ...

Depends on how the hardware is implemented. If it's a buzzer, then no chance of changing it. It needs to be a software controlled piezo element.
This new meter looks like it uses a buzzer.

Flashing the screen AND beeping would be very valuable.    Also adjustability in volume would make a huge difference.   I find most continuity beepers to be almost useless out in the field in a manufacturing plant.   I'm talking cases where the meter isn't any further away than standard test leads would allow.   So more engaging signaling to the user is something that should be looked into.    Sometimes I think an LED bar graph dedicated to this need would be grand (fast and bright), but that might look like a kludge.

I just noticed that the new meter has much faster updating in DC voltage and current mode in Record mode, and they have confirmed 10 times per second, so twice the usual update rate.
Very interesting.

I asked if it's possible to get the 10 times/sec updating in normal V/A modes, and they said if you want the fast 10/sec updating just use the Record function.
Only problem is the damn thing beeps all the time.
I presume it's possible to have 10/sec updating and they software slow it down to 5/sec. They have confirmed there is no loss in resolution in the 10/sec mode.
Would people prefer 10/sec or 5/sec in normal mode? (or a power-on option as I suggested to them).

Beeping can be irritating at times but I'd rather that it is never shut off entirely.   the meter should beep for example in an error state or when something like the battery is about to fail.   So in some cases beeping should never be overridden however in normal mode the more control you have over sound generation the better.   I realize this is a handheld and there is a limit to what can easily be built into such a device.

As for update rates there are time faster is better and is one reason why an analog meter can still be useful.   Some times you just need a quickly seen indication of the inputs direction / behavior.   Finding ground faults in a machine is one example where quick is good.

That's what the 50/sec bargraph update rate is good for.
