Continuous temperature measurements using an Agilent 34970A DAQ?

[channemann]

I am attempting to build a LabVIEW 8.6 VI to measure and record temperature using an Agilent/HP 34970A DAQ/Switch Unit with a 34901A 20-channel multiplexer and K-type thermocouples. I am using an RS-232 serial cable for communication. I have succesfully performed some basic measurements using the driver found here, specifically using a mashup of the HP34970A Conf Temp, EZ Temperature, and Advanced Scan Example VIs included in the driver. I have encountered several errors along the way (mostly Error-103 on the DAQ, indicating an invalid seperator in a command), and have not been able to take continuous measurements (for data logging, graphing, et cetera). What is the easiest way to accomplish this?

I would also be content to use SignalExpress, but have not been able to get the appropriate drivers to functions.

Thanks

Hi Channemann,

Is the device properly configured to take these measurements?  Also, is there a time delay needed between readings?   The error indicates that the device may not be in a proper state, or one of the commands that you're sending is invalid.  Are you able to narrow the error down to a specific event happening that causes the error?
