And.......So you can stack um!


The only 2 answers you should pay any attention to because sooner or later they will be the only 2 things you will consider when you see/""need"" new instruments or equipment......YOU'LL SEE!!   >:D  >:D >:D

Never run out of batteries.

Higher precision acquisition, or faster acquisition at lower precision.

Remote SCPI control (including high speed acquisition) - in modern instruments using VXI-11 over ethernet.

In many cases multiplexed inputs that lets you scan many measurement points from a single instrument.

In modern instruments, a larger display for things like tabulated probe hold readings and statistics.

4W measurements.

Stackable.
Cerebus:
Two things that haven't been mentioned:

1) Reading speed. Most handheld DMMs run at a few readings a second, the fastest bench DMMs can run at 100,000 4.5 digit readings a second. If you need to measure fast events more accurately than an oscilloscope can then you need this. It's also a question of throughput. It's no accident that a lot of these high speed DMMs end up in racks on the test equipment for electronics and semiconductor production lines.

2) Accurately triggered readings. Most higher end bench DMMs have a trigger input that you can use to get readings at well defined times related to what your DUT is doing.

New 4 1/2 digit bench DMM's are available.

I know!
You can get 4.5 digit meters as hand held OR bench meters.
I have 2 hand held 4.5 digit meters.
I know you can get them as bench meters as well.

As far as I know you can ONLY get 5.5 digit meters as bench meters.
The same is true for 6.5, 7.5 and 8.5 meters.

So my original statement was correct

Your statement was a bit ambivalent as it can be interpreted as "bench meters with less than 5,5 digits don't exist" or "5,5 digits or more are only available in a bench meter".

The BM869S does 5,5 digits in a handheld meter, but only on DC.

Then you've never seen a good bench DMM display that can be seen from meters away. 
Try that with a HH DMM. :P

Did you read the sampling speed speck for that bench multimeter?
