This page introduces you to the front panel controls on your pump. If you have an OEM pump, there will be no controls on the front panel and you can only control the pump from a computer, using a terminal application or SyringePumpPro.
Pumps with front panel controls can be operated via computer in the exactly the same way as an OEM pump. You will need computer interface cables.
Grab the manual for your pump
To get a deeper discussion on what your pump does in response to these buttons, and the interpretation of the information displayed (not in an OEM pump) grab your pump’s manual from here.
