From 0.1 to 14.0 mm Syringes smaller than 10 mL: Volume units are ‘ µL’
From 14.01 to 50.0 mm Syringes greater than or equal to 10 mL: Volume units are ‘mL’
6.1.2 Changing Volume Units
The Volume Units used for accumulated volumes and the “Volume to be Dispensed” settings can be changed to
either ‘mL’ or ‘
µL’. Volume Units can only be changed while the Pumping Program is stopped. A change in the
Volume Units will affect all “Volume to be Dispensed” settings in the Pumping Program.
To change the Volume Units, display the “Volume Dispensed” by pressing the “Volume” key once or twice. The
current Volume Units and the “Dispensed” LED will be lit.
Set the Volume Dispensed to 0.000 if it is not zero: Press and hold any up arrow key until the Volume Dispensed
is set to 0.000.
Now, pressing any up arrow key will change the display to and the current Volume Units will blink.
Then, press any up arrow key to switch the Volume Units between ‘mL’ and ‘ µL’. Press any non-arrow key or
wait 2 seconds to enter the new Volume Units. The display will blink when entered. The selected Volume Units
will remain in affect and override the default Volume Units. Changing the diameter will no longer change the
Volume Units. Performming a system reset will cancel the override and allow the Volume Units to change to the
default Volume Units when setting the syringe diameter.
6.2 Start/Stop Triggers
The Pumping Program can be started or stopped from three sources: The keypad ‘Start/Stop’ key, RS-232 ‘RUN’
command, or the TTL I/O Operational Trigger input. Each can control the Pumping Program’s operation.
6.3 Operating the Pump
When the “Start/Stop” key is pressed, the Pumping Program begins to operate, starting with Phase 1. If the current
Program Phase specifies a pumping rate, the pump will begin pumping, and the ‘Pumping’ LED will be lit. The
pumping direction will depend on the Phase setup.
While pumping, the pump will pump continuously in the current Program Phase, unless a “Volume to be
Dispensed” is set, or an Event trigger is set. If a “Volume to be Dispensed” is set, the Program Phase will be
complete after the set volume has been infused or withdrawn, measured from the start of the Phase.
The display can be changed by pressing the ‘Rate’, ‘Volume’, or ‘Diameter’ keys.
6.4 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:
6.5 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, display the pumping rate by momentarily pressing the ‘Rate’ key. With the pumping rate
is displayed, press the up arrow keys to change the rate. The rate units will blink while entering the rate. Rate
units cannot 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
will begin to pump 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.
6.6 Volume Dispensed
When the total accumulated volume pumped is displayed, the ‘ml’ or ‘ µl’ LED is lit and the ‘Dispensed’ LED is lit.
Volume is computed based upon the syringe inside diameter setting. The accumulated Volume Dispensed can be
displayed by pressing the ‘Volume’ key one, two, or three times, depending on the current display.
