Keysight 34461A initialize.vi not working

[AdrianOstrycharczyk · Accepted solution]

Hello. I recently switched from USB port to LAN port using ProCurve Switch 1700-24 and my DMM works perfectly fine. The issue was the USB port in DMM was not working correctly. Thanks everyone for trying to help.

I just recently ran into the same issue.  I found that the Default Setup String that is used is causing the "Lockup".  I haven't investigated further into why.

I just removed it from the places it was called.

This is in Default Instrument Setup.vi in the Private folder.

Now Initialize works for me and all the other VIs I've called.

FWIW, the "Reset" sub-VI (within the "Initialize" VI) also hangs when the instrument is a Keysight 34465A DMM.

I have had issues with Keysight 33509B, 33510B and  53220A devices.
@ LV2017, both LAN and USB communication was ok.
@ LV2023, LAN still ok, USB hangs in Init.
As far as i know, the sequence in "Default Instrument Setup.vi"
*ESE 60;*SRE 48;*CLS;
set first the registers and then the *CLS clear them.
When i just run the clear part *CLS and cut out *ESE 60;*SRE 48,
USB communication works also fine.

I have had this issue with Keysight 34460A (digital multimeter).
It seems that I solved this issue by installing the following driver,

Keysight IO Libraries Suite 2025.

Another option is set SPCI command "*ESE 60;*SRE 32;*CLS" in Default Instrument Setup.vi;
Original command was "*ESE 60;*SRE 48;*CLS".

That makes NO sense!  Erase everything but two bits, then Erase a few more  AND FOLLOW UP BY clear...
