I have a DOS that was operating on the classic system and recently upgraded to the new Apex. I started introducing all the modules one by one. I connected the "USB" cable to the DOS and primed both pumps from the display module. When I go to calibrate the pump - the pump spins and the volume in the graduated cylinder is 30 mls. The variation in the display module for set up only allows you to change the amount plus or minus 5 mls (35 to 45 mls). Suggestions?
