Keithley DMM IVI Read Timeout

[StevePenny]

We are controlling a Keithley 2000 series DMM using the IVI Dmm Step in TestStand version 3.0.
The logical name has been set-up using MAX version 3.0.2, the logical name references the ke2000 driver session. When run under TestStand the DMM configures correctly and will take a first reading correctly but subsequent reads fail with a timeout error. We’ve tried using the LabWindows example code found in directory \program files\ivi\drivers\ividmm\examples\cvi, this exhibits the same problem found use TestStand. Is this a MAX set-up problem, any help will be appreciated.

Below is listed the software/environment we are using with the DMM:

Software Version
IVI Compliance Package 2.1
NI VISA 3.0.1
NI-488.2 1.7
Instrume
nt Driver (LabWindows/CVI 6.0) 3.02
Measurement and Automation Explorer 3.0.2.3005
TestStand 3.0
CVI Runtime 7.0.0.393

Hello Steve Penny �

What is the exact error code you are receiving? You can find a list of common GPIB error codes and solutions here.

Make sure you are using the correct driver for your GPIB board. Windows XP also uses NI 488.2 version 2.1. 

If these suggestions do not solve your problem, please post the error code so the matter can be further investigated. Have a great day!

Installed NI 488.2 vserion 2.1 which made no difference.

Discovered that two other devices on the bus were raising an SRQ at startup, once this was disable DMM reads were performed correctly.

Thanks for your help
