Pressing the ‘Volume’ or ‘Diameter’ keys will display the current “Volume to be Dispensed” or the syringe
diameter setting while the key is held.
7.4 Purging
To purge the syringe, with the Pumping Program stopped, press and hold the 'Start/Stop' key. The Pumping
Program will start then, after one second, purge will begin. The pump will pump at its top speed in the
currently set direction. Purging will continue until the 'Start/Stop' key is released, and then the pump will
stop. While purging the display will show: .
7.5 Changing the Pumping Rate and Direction While Pumping
Except with some complex Pumping Programs, the pumping rate can be changed while the pump is
operating. To change the pumping rate, momentarily press the ‘Rate’ key. While the pumping rate is
displayed, press the arrow keys to change the rate. The rate units will blink while the rate is being changed.
If the arrow keys are not pressed, the display will return to the “Volume Dispensed” display after a 2
second delay. Rate units can not be changed while pumping.
The new rate is stored after a 2 second delay or by pressing a non-arrow key. If the new rate is within the
operating range of the pump, the display will blink and the new rate will be stored in the current Program
Phase and the pump begins pumping at the new rate. If the new rate is out of the operating range of the
pump, the display will show
nn
. Pressing any key clears the error message.
The pumping direction can be changed while pumping if the “Volume to be Dispensed” is 0.0 (off).
Pressing the direction key will immediately change the pumping direction and store the pumping direction
in the current Program Phase. Also changing the pumping direction changes the accumulated “Volume
Dispensed” according to the new pumping direction.
7.6 Volume Dispensed
While pumping, the display will show the total accumulated volume pumped with the ‘ml’ or ‘ l’ LED lit
and the ‘Dispensed’ LED lit. Volume is computed based upon the syringe inside diameter setting.
The volume is accumulated separately for infusion and withdrawal. When the pump changes direction, the
“Volume Dispensed” changes to the accumulated volume for the current pumping direction.
The “Volume Dispensed” accumulations, for infusion and withdrawal, are reset to 0 when:
A) Pressing and holding any arrow key while displaying the “Volume Dispensed”.
B) A sub-program is selected when the Pumping Program executes a Program Selection function.
C) The syringe diameter is changed.
D) From the RS-232 clear “Volume Dispensed” command (CLD).
E) The accumulated Volume Dispensed rolls over from 9999 to 0.
F) The pump is powered on.
When the Pumping Program is stopped, and the display shows the Program function or pumping rate
information, the accumulated Volume Dispensed can be displayed by pressing the ‘Volume’ key one, two,
or three times, depending on the current display.
7.7 Resuming When Paused
If the Pumping Program is stopped before the completion of the Pumping Program, the ‘Pumping’ LED
will blink, indicating that the Pumping Program is paused. While the ‘Pumping’ LED is blinking, starting
the pump again will resume the Pumping Program where it was stopped. This means that the Pumping
Program will continue at the point in the Phase where it was stopped and the ‘Volume to be Dispensed’ will
still be referenced from when the Program Phase first started.
Pressing any key other than the ‘Start’ key will cancel “Pumping Program paused” and the ‘Pumping’ LED
will stop blinking. When the Pumping Program is started again, it will start from the beginning (Phase 1).
