Pump calibration duratrion

I’m trying to calibrate my pumps (from pioreactor) and the instructions say i need an accurate graduated cylinder or balance with .1g accuracy. For the pump durations that are given (.65 s to 1.something) the pumped water is about 0.06 g. Not measurable in a graduate cylinder and very hard to measure in open air on a scale. Is there a way to change the pump duration range for calibration? wouldn’t longer times be more accurate?

Good points! We do have some control over the duration. Check out the output of pio run pump_calibration --help, you should see options for --min-duration and --max-duration.

Ex:

pio run pump_calibration --min-duration 1.0 --max-duration 3.0
