5.1 Syringe Inside Diameter
Set with command: DIA <float>
The syringe inside diameter can only be set while the Pumping Program is stopped.
Valid syringe diameters are from 0.1 mm to 50.0 mm. If the diameter is out of this range, the response will be
‘?OOR’. Changing the syringe diameter will not zero any current settings. Section 10.7, “Syringe Diameters
and Rate Limits”, is a representative list, for reference, of syringe diameters for various syringe manufacturers
and syringe sizes.
5.1.1 Default Volume Units
The units of the accumulated infusion and withdrawal volumes and the “Volume to be Dispensed” are set
according to the diameter setting. NOTE: A change in the volume units will affect all “Volume to be
Dispensed” settings in the Pumping Program. If the default volume units are changed (see next section), the
selected volume units will remain in effect until a reset function is performed.
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’
5.1.2 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’. A change in the volume units will affect all “Volume to be Dispensed” settings in the
Pumping Program.
Set the volume units command:
VOL { ML | UL }
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 (*RESET) will cancel the override and
allow the volume units to change to the default volume units when setting the syringe diameter.
5.2 Start/Stop Triggers
Start Command: RUN
Stop Command: STP
The Pumping Program can be started or stopped from different sources. The “RUN” and “STP” commands, or
the TTL I/O Operational Trigger input. Each can control the Pumping Program’s operation.
5.3 Operating the Pump
When a start trigger is received, the Pumping Program begins to operate, starting with Phase 1. A different
starting Phase can be specified with the RUN command. If the current Program Phase specifies a pumping
rate, the pump will begin pumping. The pumping direction will also depend on the Program Phase setup. The
volume dispensed can be queried with the 'DIS' command.
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.
