If you use VISA to write and read ascii strings, you can keep TSP mode and do really cool tsp stuff.
i got a DMM 6500 and connected it to the computer with an USB-cable.
I am using Labview 14.00 and the NI-driver to control the instrument via Labview.
As suggested above, i changed the scripting language to SCPI in order to use the Labview driver.
Using VISA-connections i made sure that the device is listing ( tested *IDN?\n and read it out).
But when i run the "series scanning low level DCV.vi"i encounter some errors:
Unless i choose pseudocard 0 (no pseudocard), the configure pseudocard vi fails with the statement invalid parameter.
If i am using pseudocard 0, i get an error during the configure measurement step, cause any channel list selections returns in valid parameter in channel list.
I just try to use the FRONT/REAR channel to measure a voltage.
Whats the correct entry for the channel list to do this job? (I found nothing in the manual about this.)
Is using no pseudocard correct? Or do i need one? In which one would that be?
thanks for the help
If you just want to measure with the front or rear input terminals then you will not need an instrument card. A pseudocard is used for setting up or troubleshooting a test that uses a scanner card, but it sounds like you'll only be using the terminals that come with the instrument? The driver should support measurements without a scanner card.
If you do need a card though, the DMM6500's only valid pseudocard is "2000", which emulates a 2000-SCAN or 2001-TCSCAN scanner card.
If you think there is a problem with the driver or .vi program, I would reach out to National Instruments as they handle support for labview. The DMM6500 driver page is here. On the top right of the page you will see a link for Request Support.
The DMM 6500 supports only the pseudocard 2000, which is not contained in the Labview driver.
To bring things to a good end, someone has to rewrite the configure pseudocard.vi by adding the "2000" to the dropdown constant and the textblock for the SCPI command.
But I'm worried the "series scanning low level DCV.vi" might not be the vi you really want for your application. The pseudo card won't allow you to make any measurements so you should not not configure one when actually taking data. Unless you plan on adding a scanning card later? Or maybe I misunderstand your application?
