Buck-Basic-1/5/12 - Pump - Instruction Manual

The BUCK-Basic Series Pumps have multi-function keys that change their functions depending on what Menu or Sub-Menu you are in. You must first stop pump Operation with HOLD before you can turn the pump off with OFF. Also use this key to return from sub-menus. ENTER OFF Reset parameters or flow rate, or access any of the other functions in the Main Menu. This gives you the programming and operational flexibility for changing media or flow rates, shift sampling, interrupted and ad hoc sampling and other situations where you may just want to pause the pump without actually turning it off.
