You mean for daily calibration? Unless they changed things from the 2100 yes. I use it every day on our Versant 2100. Once a month though I have to calibrate use the EFI ES-2000 then an go back to the full width array.
I was wondering because with FCP 5 it was supposed to support some inline instruments. I know it does not support the 2100 FWA but I was wondering for those that have the 3100 can you choose to use the FWA in FCP 5.
