Model NE-300 Syringe Pump
Publication #1200-01 8 08/27/14
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.
Then, pressing any up-arrow key will change the display to and the current volume units will
blink.
Now 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 effect 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 Operating the Pump
When the “Start/Stop” key is pressed, the Pump will begin pumping, and the ‘Pumping’ LED will be lit. The
pump will pump continuously at the set pumping rate until stopped.
Either the pumping rate, “Volume Dispensed”, or syringe diameter can be displayed while pumping. Press the
relevant key to change the display. While displaying the pumping rate, press the up arrow keys to change the
pumping rate.
Warning: The NE-300 does not have stall detection. The pump must be stopped manually when the
syringe is empty or the motor force is exceeded. The white drive nut block can be damaged when the
pump is operating while the motor cannot turn. This will violate the warranty and replacement of the
drive nut block will not be covered.
6.3 Purging
To purge the syringe, with the Pump stopped, press and hold the 'Start/Stop' key. The Pump will start
pumping, then, after one second, purge will begin. The pump will pump at its top speed. Purging will
continue until the 'Start/Stop' key is released, and then the pump will stop. While purging the display will
show: .
Press and hold the direction button, to perfrom a reverse purge. The display will show:
6.4 Changing the Pumping Rate While Pumping
The pumping rate can be changed while the pump is operating. To change the pumping rate, display the
current pumping rate by pressing the ‘Rate’ key, if needed. With the pumping rate displayed, press the up
arrow keys to change the rate. The rate units will blink while the rate is being changed. 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 memory and the pump
will begin pumping at the new rate. If the new rate is out of the operating range of the pump, the display will
show . Pressing any key clears the message and restores the previous rate.
6.5 Volume Dispensed
The accumulated Volume Dispensed can be displayed at any time by pressing the Volume key. The display
will show the total accumulated volume pumped with the ‘mL’ or ‘µL’ LED lit and the ‘Dispensed’ LED lit.
Volume is computed based upon the syringe inside diameter setting.
The “Volume Dispensed” accumulation is reset to 0 when:
A) With the pump stopped, pressing and holding any up arrow key while displaying the volume.
B) The syringe diameter is changed.
C) The accumulated Volume Dispensed rolls over from 9999 to 0.
D) The pump is powered on.
