Same "axis numbering" problem on my brandnew 34465A:

2.5 , 2.5000 , 2.5001  - WTF?  :palm:

Isn't there enough place for:
2.49995 , 2.50000 , 2.50005

--- End quote ---

It's actually...
2.500 10
2.500 05
2.500 00

But, yeah.  Agreed on the :palm: for rounding and truncating axis labels in the first place.  You're not the first to trip over this!

At first, yes, there is not enough space to display all these digits. It's a 4.7" LCD only, and for an old man like me, some numbers are already too small to read, sometimes.

2nd, the rounding usually is done properly with the latest FW 2.14 (a similar issue has already been addressed in a recent version).

It is disturbing, anyhow, as this often gives identical numbers for 2 of the 3 labels.

3rd, in this case the limits are more probably 2.499 95 / 2.500 00 / 2.500 05, which would precisely be rounded to 2.5, 2.5 and 2.5001, as displayed.

Instead of guessing about that, you may use the "Vertical Scale" menu, select 'Manual', and then set Low and High parameters.

Here, the real limits are displayed to 6 to 7 decimal places, I think, and you also can then define the appropriate Y=window, which often is not set optimally, when using AutoZoom.
Afterwards, you might leave this menu again, to have full view of the measurement window.

I've seen a better solution for that space vs. resolution problem, I think, it was on the KEI 7510, i.e. the 'base value' is displayed to one or two decimal places somewhere on a major tick, and the major ticks divisor is displayed separately at the top.
In this case , that would be displayed as '2.5' and major ticks as '5.0E-5', minor ticks then would be 1E-5.

Such an engineering format would also be useful for the StD value, to overcome the same problem of small differences, also.
So I totally agree to HighVoltage, that KS should make another update for that.

Yep >,<"... The DMM7510 solves this problem quite elegantly as demonstrated here:



Not my DMM! Could never afford this beast!~

But I also had a big face-palm moment when I first encountered this problem with my 34465A.

Also thank you for replying to my earlier message regarding the Trend Chart!~

It's explained in the RTFM, or in the HELP menu.
Press <Shift> DISPLAY, and then there should be an item inside the file management items, labelled as screen shot.
(Don't have my instrument at hand right now.

The display content, just before you press <shift> will be stored.

I dunno.  That looks like ass, IMHO.  With a wide-aspect display like this, it certainly wouldn't have done any harm to spend a few horizontal pixels replicating the +5.04 at every graticule line.

Graph rendering isn't a ripe subject for "innovation" unless you're absolutely certain you're improving things.  If this labeling method didn't catch on in the 400 years since Descartes, what are the odds that it's the right thing to do now?

OK...?
I had no problem to find space for the additional (one) digit, see attachment.
(The red marked distance is unchanged, but could be reduced, too.)
