Channel missing & write the data in .csv file

eevisi.chen — Mon, 01 Jul 2019 01:31:38 GMT

Dear Sirs:

I started my 1st LabVIEW program for ThermoCoupling by Agilent 34970A + 3 cartridges of 34901A,

which should able to collect 60 data from every scan.

But review my .csv file, I see only 31 columns of data are recorded.

Can anyone give me some advice where I did wrong?

By the way, I would like to add some header which can help to indicate the channel name in the first few rows in .csv file.

Could I use "White delimited spreadsheet.vi" to do it?

Thanks in advance

eevisi

Maybe can't use the channel list string "101:120,201:220,301:320",You'd better get one channel each time.I found that issue before,But I don't know why can't get 60 datas.

Hi Weschen:

Can I know how did you solve the issue?

As you recommend, I have tried to key-in all the channel name (101,102,103....201,202, ...301,302,...320)

instead of the range (101:120, ...201:220, ...)

But the results keep same as before, seems the program can only catch data from 30chs by every can..

Kindly advise & thanks a lot~

Hi eevisi,

But the results keep same as before, seems the program can only catch data from 30chs by every can..

If this is the case then that limitation is within your DMM or its device driver functions.

(You may ask Agilent for support!)

What's inside those device driver VIs?

What's mentioned in the manual of your device? (Did you even read it?)

Why are you using the advanced configuration AND the EZ-config VI's?

I have posted several examples on how to properly use this instrument. Search for 34970A and 34972A

Until you start using a proper program architecture like a simple state machine your results are going to be very poor.
