Agilent 34970A Error Message

[KowdTek]

Hello, I'm using Agilent 34790A with EZ Temperature.vi. I assumed that everything is configured with the instruments but when I click RUN, I get one "beep" and an error message (err -420). Does it means that I still need to configure the vi? Any help would be appreciated. Thanks!

I don't remember what error 420 is. Can you provide the explanation from the manual? It might jog my memory. I no longer use it but I did for several years.

p.s. You posted to the wrong board. this is for NI DAQ boards. Next time, post to the instrument control board.

Query

UNTERMINATED

The instrument was addressed to talk (i.e., send data over the interface)

but a command has not been received which sends data to the output

buffer. For example, you may have executed a

CONFigure command

(which does not generate data) and then attempted to read data from

the remote interface.

Sorry for posting in the wrong board.

I don't remember ever getting that error but the driver has been changed numerous times since I started using it. My recomendation would be to start small and run the functions one at a time. Start with the initialize function and then see where the instrument is generating the errror. I don't have the driver installed here but I know there are other top level examples. You could try running one of those.

Ok thanks for your replies.

I just tried and I'm getting the error right @ Visa Read and the error changes to err -103

Here's the explanations:

-103

Invalid separator

An invalid separator was found in the command string. You may have

used a comma instead of a colon, semicolon, or blank space – or you may

have used a blank space instead of a comma.

Examples: TRIG:COUNT,1

or

CONF:FREQ 1000 0.1

That's odd too. I never experienced that error and I used the 34970 in several different variations for a number of years (but not the thermocouple, though). I'll try to look at the manual within a day or so and the latest version of the driver. I'm not sure what you can try in the meantime. One thing that comes to mind is to verify that in MAX, the GPIB controler is set to send only EOI.
