Area Display
1 This area of the display shows the current state of operation (if any). Time is shown when ramping.
Stop
The pump is stopped because:
• the STOP button has been pressed, or
• a stop signal has been sent from the software, or
• a pressure limit — stop action has been received, or
• zero flow rate has been programmed.
Ramp
The RUN button has been pressed and the pump is ramping to a new value. The elapsed ramp time is also shown in
this area.
Hold
The HOLD button has been pressed and the ramp has been interrupted. The pump continues at the flow rate
reached when the HOLD button was pressed. The HOLD state can be canceled by pressing RUN or STOP.
2 Current flow rate is shown here.
3 Current system pressure is shown here.
4 Ramp time is set here, in minutes decimal format, (for example, 2 min15 s is set as 2.25 ). Ramp time is the time for
a linear change from current to new flow rate.
5 The flow rate is set here. (–xxx.xx — indicates active cursor). Legal flow rates are from zero to the maximum for the
pump head installed (200 , 500 , 800 or 3200 mL/min).
