What are - for you - the 3 biggest disadvantages of your benchtop DMM(s)?

(1/23) > >>

PushUp:
As I - and probably some others - plan to buy a benchtop DMM or further benchtop DMMs, this probably helps, to filter and watch out for your own needs just by elimination?!



You don't need to mention three disadvantages, when there is only one for you...just put it in a nutshell.

Here are some examples - I hope they are right:  ^-^

Although the price can be a disadvantage, it is better to skip this point, to focus on your personal preferences, for example:

Keysight 34465A
1. price   no "AC+DC" true RMS value
2. 100uF max is a joke
3. ...

Rigol DM3068
1. a green (and blue) LED lights up, but does not show the voltage drop in diode mode

The SnapShot is out of this video, which is 8 years old: https://www.youtube.com/watch?v=eR0TM3eitNk

Correction:
In order to update the outdated video footage...

It is also possible to see the voltage drop with different current values now having specific upper voltage limits:



...in this case with "100uA = Measure Range: -0.2V to 4.2V" for a white diode:



2. too small Display for trend chart
3. hardly any useful 2nd display combination, such as AC vs. DC

Rohde & Schwarz HMC8012
1. maximum current load above 5A only for 30 sec., followed by a pause of 30 sec.
2. no auto ranging for 2nd display
3. 500uF max is better than Keysight but still useless

Keithley DMM6500
1. quite long dimensions like an old analogue Scope
2. mainly touchscreen (might be a benefit for others)
3. ...

If someone is very disappointed from very old and known firmware bugs, it is probably useful to name them, but all under its own category "FW-Bug".

Siglent SDM3055
1. a blue LED lights up, but does not show the voltage drop in diode mode

The SnapShot is out of this video, which is 5 years old: https://www.youtube.com/watch?v=rmTP-aR3CxQ

Correction:
As mentioned by tautech, it is solved: https://www.eevblog.com/forum/testgear/siglent-new-bench-dmm-sdm3055/msg3028294/#msg3028294



2. ...
3. ...
FW-Bug: https://www.eevblog.com/forum/testgear/siglent-new-bench-dmm-sdm3055/msg3328326/#msg3328326


It is useful to mention a missing option, although it is known from the beginning, but reveals that it would have been nice to have with hindsight, for example:

Keysight 34460A
1. no trend chart
2. DCI & ACI measurements only up to 3A
3. ...


ThanX & Cheers!  :-+

No bip in continuity mode, like fluke 8012a. Why fluke, why?

After 7 years with only handheld DMMs and now having a bench DMM I’d say other than not being portable there aren’t many (any?) disadvantages to a bench DMM other than cost.  You can’t buy a bench DMM for $25 (like an Aneng 8008) but if your budget can justify a Siglent 3055 it might be hard to justify a Fluke 87V for a similar price (unless you need portable).  I think a Siglent 3055 and a good (enough) handheld would be a good first two DMMs (everyone who wants to learn/do electronics should have at least two DMMs).  So the entry is two 8008s and where you go from there is up to the you - but one handheld DMM and one bench DMM might be a good objective.

1  totally  hate any vfd display based meter ---- if they have unobtanium parts
2  lack of a simple acquisition software  if they have a serial / lan / gpib or usb port ...  unless someone has done a great job of building one   :-+
3  repairability / schematics

4  At least a good diode test around 5 volts would be perfect loll     unless you have an eevblog 121gw  who could do a 15v diode test ??



But the list would go on and on  loll           

My dream would be a nice meter say at leat a 5 1/2 digits  with an added lcr meter in it like an De-5000, franken meter  loll

My problems is :  i have the Fluke 189 habits, totally love the way they work, display resolution, good accuracy, some data logging, and i have their bp-189 battery pack, sure they get old  and some parts are hard to get, and i loooove the fuses acess if needed.

I have the same fun with  An Amprobe am-140  but i hate the fact, i have to open the meter if i blow a fuse (wich never happened)

For my 34401a,  well  they get old, but are rock solid, schematics are available,   now you have some vfd clones available, you can extend their lives ... i did it for one of my meter, aaannnd  no fans  :-+
