The ZERO PRESSURE key will correct pressure sensor drift. Before
pressing ZERO PRESS, the pump should have port fittings installed,
and be depressurized.
1. Open a valve, or loosen a fitting other than one on the pump, to
ensure the cylinder pressure is actually zero.
2. Press ZERO PRESS. The display will show the current pressure
and ask if you want to zero the pressure.
3. Press 'A', 'B', 'C', or 'D' to zero the desired pump.

If the pump is not depressurized, press

When using multiple pumps, there are four multi-pump operating
modes of delivery and one Independent Mode:
• Continuous flow in Constant Flow Mode
• Continuous flow in Constant Pressure Mode
• Modifier addition in Constant Pressure Mode
• Modifier addition in Continuous Flow, Constant Pressure Mode
• Independent Mode
A SyriXus series continuous flow pumping system in Constant Flow
Mode will consist of two syringe pumps and a valve package, all regu-
lated by one controller. Installation and operating instructions for this
system are provided in Section 5 "Continuous Flow Introduction,
Installation, and Operation".
Two pumps regulated by one controller can be used to create a mod-
ifier addition system. This arrangement will require user supplied
hardware (tubing, fittings and valves) to implement. For additional
information on modifier addition systems, refer to Section 6 "Modifier
Addition".
In these modes, the softkeys toggle between the options described in
Table 3-3 "Key Functions in the Multi-Pump Mode".
Uses a finer (slower) pressure match control when switching from one pump to the
other.
Uses a coarser (faster) pressure match control when switching from one pump to the
other.
Uses pressure matching when switching from one pump to the other
Uses no pressure matching when switching from one pump to the other.
Sets the pump into the Delivery Mode of operation.
Sets the pump into the Receive Mode of operation.
Sets the fill and refill marks that are used with both Continuous Flow Modes.
Sets the NCV feature On/Off. Refer to Section 5.5.4 "No Check Valve".
