I_V sweep in keithley

[jyot445]

hello,

I am new to labview.I am doing the the solar IV characteristics with this program in keithley 2420.

the problem i am getting is that the voltage which coming after all the logic operation is in integer form rather than float value .i didn't find anything related to it on the palette

 I want to append the data of all the measurement in a single file of one day rather than creating any new file for each measurement.like if i have taken one measurement for the reverse measurement it shouldn't be asking for new file rather than appending in the same file with a title as required

Also my graph is not showing the currents in microapmeres rather its showing in ampere .

can anyone please help me out.

Hi iyot,

any chance your computer is set to use the comma as decimal separator - instead of the point used by most computers worldwide and mostly all external measurement devices? (The most common reason when measurement values aren't converted correctly from string to numbers.)

Solution: Adapt your format codes to accept decimal points…

Hi iyot,

for the response but can you please elaborate it more?

So you want to answer my question from my previous message?

And did you read the LabVIEW help for those formatcodes to learn about handling different decimal point/comma formats?
