Channel missing & write the data in .csv file

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
