Can't export detected volume

[bloopity]

Hi everyone!

I’m setting up a Tecan (Freedom EVOware Version 2.7) to detect volume in tubes and am having trouble exporting predefined variable ‘DETECTED_VOLUME_X.’

I’ve tried to set a variable ‘MyVol1 = DETECTED_VOLUME_1’ after the detect liquid step and come across the error ‘Variable DETECTED_VOLUME_1 not defined.’

I’ve read that only the Freedom Plus version can export detected volumes, but that seems wrong to me since my software offers this liquid detection step.

I’ve attached some screenshots. I’ve also tried:
Set Variable: Vol = ****
Detection Step
Set Variable: Vol = DETECTED_VOLUME_1 (as a number)
Export

This only exports “DETECTED_VOLUME_1” in my .txt file.

Any help would be greatly appreciated, thank you!

You have to have a line in the script to set DETECTED_VOLUME_1 in order to define that variable. You can just put a line at the very beginning of the script that sets that variable to 0.

This seemed counterintuitive to me but even for the built-in variables you have to call set on them once before you can use them.
