I'm writing a scientific thesis in English but I'm not a native speaker.
I think this sentence is correct, but I am not sure (that's why I ask this here rather than in "Writing") and I think it does not look nice. I am also not sure when I should use which tense. Especially when writing about an experiment I did in the past.
Can someone come up with a nicer way of writing it in an academic style?
The poured amount is then checked if it is above zero before being added to the trajectory list.
(For more background what this sentence is about: The poured amount in this case is a variable in a program. Obviously it should be above zero, but in case there is an error of some sort its value is checked just to be sure it's really above zero.)
