No beep above 0.85 ish volts
Short beep from 0.84 to 0.10 ish volts
Below 0.1 volts, a continuous beep.

I have a agilent u1252b which does this as well. I don't have it at hand atm so I can't check how fast it is or at which voltages. But I like this option a lot, it let's you easily spot diode's while probing around.

As for the speed I agree the 121GW(v1.51)  feels very slow. I measured it, and came to 0.5 +/- 0.1 second, where in resistive mode it's more like 30msec. Also the bar graph is very fast in diode mode, so I'd say it should not be difficult to make it beep much faster.

And for sure this can be corrected in firmware with a little effort ... just one more small issue on the list

You have been perfectly clear - redundantly clear, repetitively and tediously clear.   It's not an issue because the 121GW is not specified to do what you want and never was. The unnamed models you like were probably specified to do it. They also probably have a higher price point,and generally a different feature set than this one. In future purchase decisions, read the specs compare the feature sets and price before making your purchase. (Is that clear?) I also expect that it cannot be corrected with firmware that this has something to do with the settling time for the A-D.  Why do you need to be clear? None of us work for EEVBlog or write firmware for the product and are in no position to do what you endlessly ask. Still you go on and on.  Speculating about others repair styles etc.   So please stop.   
CDaniel:
Your comments are not helpfull , if you don't care about an issue don't imply it's not a feature ...
This is a firmware bug like many others , this has nothing to do with price , brand ( Fluke ) or anything else .

It is laughable that you imply that someone should buy a very expensive meter just to have fast responding beep in diode mode  |O . Then how is possible to be fast in continuity mode  ? It's the same ADC . Please stop the nonsense and watch your own business .

How is continuity, passive device and active device measurement different?  Checking a diode or junction is different from checking a passive resistor has been explained and actually you should have known it given any of your claimed expertise.  You didn't read what was written to you god knows how many redundant posts back.  As for nonsense: Nobody you are arguing with can change the firmware for you.  You missed that point completely.  You insist that this is an "Issue" not an add on to what was specified.  I don't think you really have thought much about any of the responses you got.  Other than insults, none of your posts have either responded to others or introduced a new point to what you repeat.  There is no purpose to your continuing with this.

Just received my 121GW it has v1.54 FW -  just for info - I have no idea what have been changed in the FW
