DOS heads

I bought a used Apex DOS and when I run them they are pumping at different amounts over the same period of time. Does this mean one head is starting to fail or is there a setting somewhere I can adjust it?

You could try running the calibration task.

Agree that the first step is to calibrate. There certainly are wearable parts. I replace the peristaltic tube on mine about every year. Have not had to replace the rollers yet.

Thanks, I'll do that. I'll try and look up a video on how to do it. Will calibrating it adjust the amount it's flowing out?

What kind of tubing do you use?
