·       Flow: 0 to ml/min in 0.01 ml/min increments for each operational pump (0-30 ml/min total for three pumps)   ·       Composition: 0 to 100% in 1% increments for each of three components - A, B and C   ·       Gradient Programs: 10 storable programs each with 10 segments   ·       Each segment allows simultaneous changes in total flow and composition of A, B or C in accordance with any of 11 different curves   ·       Timed Event Programs: 10 storable programs, each with 20 timed events   ·       Capable of controlling 7 external devices and an audible beeper   ·        Program Memory Protection: Programs stored in memory retained indefinitely without line power or batteries. Stored programs may be modified or deleted by operator   ·       Low Pressure Limit: Settable from 0 to 5950 psi in 1 psi increments. Low pressure for more than 90 sec will cause pumps to stop.    ·       High Pressure Line: Settable from 51-6000 psi in 1 psi increments. High pressure for more than 2 sec will cause pumps to stop.    ·       Compressibility Compensation: Settable from 0 to 40 % in 0.1% increments for each of three components   ·        Environmental Specifications: · Temperature: - Operating Range: 5 ° to 40 ° C - Storage Range: -45 ° to 65 ° C   ·       Humidity: - Operating Range: 20% to 95% RH, - Storage Range 0% to 100% RH (non-condensing)
