Keithley DMM7510, SMU 2450 & 2460 problems

MegaVolt, thanks,
TSP/SCPI interface seems to be broken:   only *idn? command gets answer, others return either an empty string or timeout.
for example,
==
loadscript test
print(localnode.model)
endscript
test()
==
returns nothing. 

Also, people in our lab have an idea that previous firmware upgrade to 1.1.0s  version  could be done improperly, like 1 time instead of 2 in a row. It was long time ago and we can not check this nowdays.
The unit was working fine with this 1.1.0s, except real buttons.

You can always downgrade to an older FW version and see if the problem persist.

Lately I have no more problems with my DMM7510, it is very stable.

That's probably what I need.  But how do I do this  if screen is not working anymore?

It seems more like you can not do this yourself.

I would call them by phone.
The Keithley staff in Munich / Germany is very helpful on the phone.

1.7.1 released to address a critical fix for the SMUs (2450 atleast).

New I-V tracer app available that is installed via Kickstart 2.2.0. Seemed like a cool basic feature, until you find out it is a paid license that starts at $1500. 

Either way you can try it out for 30 days, then uninstall.

Don't they have a scripting language to create apps like this?  How hard can it be to put one together?

Can apps be controlled using SCPI over LXI?

@HighVoltage, since you have some Keithley equipment too I just wanted to point out this problem I've discovered with the 2450.

I wonder if you can verify, perhaps with your 2460 also?

Since the last few years and latest firmware update I had no more problems with either one of my Keithley's

I posted my results in the other thread

Bad screen on the top right instrument?

Bad screen on the top right instrument?

No, the refresh rate of the DMM7510 is so fast that the camera was too slow.
