Versa not pumping accurately

[Vdlibrtr]

Hello, ive got my versa pump set up to run 300ml a day, the last two days I've come home at around 8 in the afternoon where my pump should have told me it dosed 250ml that day, instead its near 60ml, and suddenly ill notice it starts to catch up and dose it all at once, is there any way I can fix this?

You should calibrate it again, that could be the issue.

it was calibrated correctly. what was happening was when I cut power to the versa it didn't keep track of how much it had dosed
