I have been using the eVOLVER without the pumps for some time, but am now looking to expand the work to chemostat. I am trying to calibrate the pumps and have the most recent version of the software installed which includes the pump calibration within the general calibration tab. When I go to run the pumps though, they should just run for 10 seconds and turn off, but they run for intervals of 10 seconds indefinitely. I am not able to stop them with the “force stop all” button and need to go into the setup page to stop them. Any ideas why this might be happening?
