Keithley DMM7510, SMU 2450 & 2460 problems

<< < (15/29) > >>

dr.diesel:
I've not seen a BSD since the last update, however using the web interface will still cause lockups, no AZ improvements.

No screen issues and mine is powered 24-7.

The AZ issue has been clearly documented and reproduced on several units, however Keithley refuses to comment on it, I suspect it will never be addressed.  I would encourage you to ask the same questions over at their forum:

As Keithley does not appear to read here, posting above might help the cause some.

HighVoltage:
Since I have installed v1.6.4c Firmware, I had no more BSD crashes.
The A/Z noise has not been addressed by Keithley, not even a word of explanation, as far as I know.
The display works perfectly from a viewing and touch perspective, no issues at all.

The DMM7510 is a really nice instrument and besides the A/Z noise, it can be highly recommended.
The ACAL works more stable, compared to the Keysight 34470A
And the instrument reads stable after only 3 min after the cold start.
Nice Christmas present!

I haven't seen a literal BSD, but it still hangs up sometimes with a certain sequence of touchscreen commands requiring a restart.

For one lab-grade DMM , low noise should be one of the key factors, otherwise  is than huge shortcoming for 7510. :--

I'm going for it. It was either a new DMM7510 or a used and questionable 3458a, since I don't "need" the 3458a's 8.5 dig but could use many of the other features the 7510 has, it won.  Should be here next Tuesday.  Early Christmas gift.
