Hi all-

Tried some searching but came up empty - are there any dual display meters made these days?  (Like the old Fluke 45, able to show two parameters at the same time.)  I do a fair bit of power supply work and would love to simultaneously read AC & DC off one pair of test leads... thanks.

If it comes to benchtop instruments, look at the Agilent 34410A and the Agilent 34411A
Or the newer models from Keysight 34461A to 34470A
They all have dual display capabilities.

There are 3 kinds of people in this world, those who can count and those who can not.

There are quite a few out there - unfortunately a lot of them read AC then read DC, then switch back to AC and repeat the cycle.  This wouldn't be bad, but a lot of them also use a Relay to do so...  with at the bare minimum will drive you nuts with the click click click click.   The fluke 45 apparently does this as well with some combinations.   See below, around 9:35.



My Rigol DM3058E does the same thing.

A while back I asked about models which actually did simultaneous AC+DC readings (https://www.eevblog.com/forum/testgear/bench-dmm-with-simultaneous-dcac-rms/) without relay clicking.   Someone recommended a HAMEG HMC8012. 

There's a quick demo of the HAMEG HMC8012 simultaneous reading here:

 

And a longer review here:



I can't give you a real review of the HAMEG, but I can say that one is currently on order (finally, after over a year of delay) for my bench.  For power supply work, look at the screen in the review at around 8:10... Voltage, Current, AND calculated power.  Also look at the stats screen around 7:00.

As others have pointed out it's only a 5 3/4 digit, and the 1 year accuracy on some ranges isn't all that hot, but the readings should be far more accurate than I need for my work.

The BK Precision 2831E does.
We just picked one up for about $300 US.

Fluke 8845a, 8846a, Tektronix DMM4040, and DMM4050 have dual display functionality.  These are more accurate, more digits, than the 45, but I keep my old 45s on the bench with my DMM4050 and 4040, because they still do some things, like audio amplifier power measurement, more easily.

Sorry for necroposting

What about GW Instek GDM-8245 ?
