(Video) Keithley 2450 Source Measure Unit (SMU) Review and Experiments

I've run into many bugs myself.  Navigating the trends, log files, output button hard locking energized.

I've had to power cycle the unit dozens of times to recover.

Did you install the latest firmware?

I experienced the auto-range issue when using the 2450 to power a small RC receiver for some tests. The receiver was resetting over and over as the 2450 was auto-ranging (set up as a fixed voltage source measuring current). All was well when I set the current range manually.

Ok, I replicated the problem. I will contact the engineer at Keithley and see what they say. I will report back.

Great, I've contacted ours in the UK too to see what they say.

Oooooo, thank you, I'd not checked in a couple weeks, glad to see they squeaked this out:   

Latest version = 2450_v1_2_0f

Did anyone get a response from Keithley on the ranging issue?

[dr.diesel]

Sure wish one could subscribe to firmware updates!

Anyhow, version v1.3.0s is out.

I will be loading the new firmware shortly.  It adds a lot of very nice features which make it more identical to the 7510 DMM on the graphing features. I will do a video of the improvements.

Ya, loaded this morning, a VERY nice upgrade, still playing around.  I'm very pleased that Keithley is dedicated to continuous improvement, I bet we still have lots to come.  Perhaps even the FFT that Shahriar mentioned in the 7510 review.

I also updated the FW on my 2450 a couple weeks ago and was very much impressed by the features and the new handling capabilities. It seems like Keithley is putting great effort in to the feature updating in new FW releases.

Firmware bump, 1.5g is out for both the 2450 and 7510.

Thanks for the info.
It looks like a long list of corrections:

Thumbs up for effort, but I cannot help myself to ask "why?". 
K2450 already have proper triax ports for properly guarded connections. I'd be also concerned with thermal issues with so much metal at the meter inputs.

If your DUT measurement results affected enough that you need shielding, it would make better results from properly guarded wiring as well.

Looking forward to your measurement results.
What is your plan? What do you want to measure like this ?
