BERTAN ERROR on GPIB error 1073676294

[atomless]

I am using code from this vi package to communicate to 8 High Voltage Power Supplies:

 http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9635659CE034080020E748...

Three of the eight power supplies tell me the right voltage.  All eight appear to work fine, but five of them will not send back their voltage to the front panel, but they all send back their correct current.

When I run the Bertan 225 simple I get the following error code:1073676294 and the voltage displays 0.0.

Thanks for any help,

Kevin

First of all, that's a warning and not an error. The fact that you are getting it indicates that not enough bytes are being requested during a read. A read would normally terminate on an EOI and not just a specific byte count. The byte count requested can be some large number.

I am not at all familiar with this instrument. My only suggestion would be to use the interactive GPIB/VISA programs in MAX to test the commands. You can use NI-Spy to capture thecommands and compare to what is in the programming manual.
