Solartron DMM plus updating drivers menu

[andrewW]

Solartron DMM:

I have successfully imported and modified the
LabWindows/CVI instrument driver for the
Solartron/Schlumberger 7150 Digital Multimeter.
The original code was written C and released
on April 12,1988, by Ash Razdan of National
Instruments Corp. Subsequent modifications by
National Instruments Corp. (staff) are as
follows: JRO on April 20, 1994, SMA in August,
1995, and DS on June 20, 1996.

Has National Instruments or anyone else done
any more work on this driver? I am aware the
instrument is long obsolete...

Updating the drivers menu:
How does one do this in LabVIEW such that the
dir.mnu file in the intr.lib directory is
kept up to date and those annoying question
marks disappear from the Instru
ment Drivers
sub-section of the Instrument I/O section
of the Functions Palette?


Thanks in advance,

Andrew

No one has done has done any more work on this driver. If you find a bug in the driver please let us know. Question marks appear in LabVIEW pallettes when VI's are missing from the locations where they are supposed to be. It sounds like the installation of the driver was not performed correctly. Here are the correct installation instructions for a traditional LabVIEW instrument driver If your dir.mnu file was overwritten accidentally you can replace it with the attachment.

Thank you for the reply, RayK.

As the instrument in question is long obsolete, I am
not surprised no further work has been done.

My findings amount to what appears to be inconveniences
rather than bugs. Specifically, the Set Integration
Time, Configure, Measure, Configure and Measure etc
do not initialise the GPIB address to be affected.
Since all the Initialize function does is set the
GPIB address,one must combine the other mentioned
functions in the same local context as the Initialize
function in order to produce the required result. I
suspect this "fragmentation" is causing the far from
expected timing responses I have been experiencing.

My initial proposition is permitting the aforementioned
functions to set the GPIB address and in
tegration time
where appropriate.

I would appreciate your opinion on this.



Best regards,

Andrew

We need to plot Bode and Nyquist diagrams from a Solartron 1250 using a GPIB and Labview. The old program was written in Turbo Pascale 10 years ago and doesn't work anymore. Can you help us with this problem?
