SP1600/1800 Programmable Syringe Pump
Publication #1200-02 8 9/15/04
5.5 ‘Diameter’ and ‘Setup’ Key
The ‘Diameter’ key allows the syringe inside diameter to be viewed and set. While being displayed, the
‘mm’ LED is lit. With the Pumping Program stopped, momentarily pressing this key will display the
current diameter setting. Pressing the arrow keys will change the current diameter (see sec. 5.4, Arrow
and Decimal Point Key). The ‘mm’ LED will blink while the diameter is being changed.
When the ‘Diameter’ key is pressed and held, ‘Setup’ mode will be entered. (see sec. 5.12, ‘Setup’ ).
When the Pumping Program is operating, pressing this key will display the current syringe diameter for
review. When the key is released, the display returns to its previous display.
5.6 ‘Rate’ and ‘Program Phase #’ Key
When the Pumping Program is stopped, except in “Program Entry Mode”, the ‘Rate’ key allows the
pumping rate to be viewed or changed. If the currently selected function allows selection of rate units,
momentarily pressing this key will switch between the ‘Rate’ display and the select rate units mode.
To change the pumping rate displayed, use the arrow keys (see sec. 5.4, Arrow and Decimal Point Key).
While the Pumping Program is operating, pressing this key will display the current pumping rate, if
applicable. After the key is released, the pumping rate will continue to be displayed for 2 seconds. While
displayed, the current pumping rate can be changed by pressing the arrow keys. The rate units will blink
while the rate is being changed. The new pumping rate takes affect when the display blinks after a 2
second delay or when a non-arrow key is pressed. The new pumping rate is stored in the current Program
Phase.
See section 11.1, “Syringe Diameters and Rate Limits”, for a list of minimum and maximum pumping
rates. A pumping rate of 0.0, will stop the pump. When the pumping rate is changed, if it is out of range
of the pumping rate limits, the display will show
nn
, where ‘nn’ indicates the currently selected
Phase Number. Pressing any key clears the message and returns to the previous pumping rate.
5.6.1 Pumping Rate Units
The pumping rate units can only be changed when the Pumping Program is not operating. If the currently
selected function allows selection of rate units (‘RATE’ function), a momentary press of the ‘Rate’ key
will enter Rate Units Change mode. The 2 LEDs representing the units will blink and the display will
show: .
Each press of any arrow key selects the next rate units, as indicated by the blinking units LEDs. When the
required rate units are blinking, press any non-arrow key or wait 2 seconds. The display will blink,
indicating the rate units are stored. The rate units are stored in the currently selected Program Phase. The
rate units can be independently set for each Phase with a ‘RATE’ function.
5.6.2 Program Entry Mode
While the Pumping Program is stopped, “Program Entry Mode” can be entered by pressing and holding
the ‘Rate’ key. Release the key when the display shows the current Program Phase number:
nn
,
where ‘nn’ indicates the current Program Phase number.
With the current Program Phase number displayed, if the currently selected Program Phase is set to a
pumping rate function, a momentary press of this key will exit “Program Entry Mode” and return to the
rate display.
5.7 ‘Volume’ and ‘Program Function’ Key
When the Pumping Program is stopped, except in “Program Entry Mode”, momentary presses of this key
will switch the display between the “Volume to be Dispensed” and the “Volume Dispensed” displays, as
indicted by the ‘Dispensed’ LED.
