2. Use the number keys, 1-4, (1-A INLET, 2-A OUTLET, 3-B
INLET, 4-B OUTLET) to toggle the desired valve to either

4. To exit the accessory control menu, press softkey D, PRE-
VIOUS.
3.5.8 ZERO PRESS The ZERO PRESSURE key will correct pressure sensor drift.
Before pressing the ZERO PRESS key, the pump should be set up
and depressurized.
1. Be sure the pump is depressurized with port fittings
installed.
2. Press the ZERO PRESS key. A message will ask if you
want to zero the pressure; and the current pressure will be
displayed on the third line of the display.
3. Press softkey A, pump A, or softkey B, pump B, or softkey

The constant pressure mode is used when the application of fixed
pressure throughout the pumping operation is required. The
pump will maintain the desired pressure by positive or negative
displacement of the piston.
Programmed Gradient – Refer to Section 7.
In the programmed gradient mode, the pump can provide the following
