Editing Function Description
PH Phase select
In Insert Phase
dE Delete Phase
When the required editing function is displayed, press the ‘Rate’/’Program Phase #’ key before the 2 second time
out. After the time out, or with any other key press, the function will be canceled.
If ‘Insert’ or ‘Delete’ was selected, the Pumping Program will be edited. While the Program is being edited, the
display will show [BUSY].
If ‘Insert’ was selected, all Phases from the selected Phase to the maximum Phase will be moved to the next higher
Phase, with the original maximum Phase being deleted. The inserted Phase will default to a ‘RATE’ function, if it
is the first Phase, or a ‘STOP’ function otherwise.
If ‘Delete’ was selected, the selected Phase will be removed, and all Phases higher than the selected Phase, up to
the maximum Phase, will be moved to the next lower Phase.
All Phases that reference the Phase number of another Phase, such as a ‘jump’ function or an ‘event’ function, will
be automatically updated. The referenced Phase numbers will be automatically adjusted to compensate for the
section of the Pumping Program that was shifted during the operation of the edit function.
Ultimately, the easiest method to maintain and develop Pumping Programs is to download the Pumping Program to
the pump from an attached computer. This would allow a single Pumping Program to be quickly programmed into
multiple pumps. The computer would only need to be attached during the download since the Pumping Program is
stored in the pump’s non-volatile memory.
Also, a Pumping Program can be uploaded to an attached computer, which could then store it and produce a
printout of the Pumping Program.
8.3 Program Function Descriptions
Each program function must be in a separate Program Phase    
8.3.1 ‘rAtE’: Rate Function
Defines a pumping function with a fixed pumping rate. This function defines a pumping setup
consisting of the pumping rate, optional “Volume to be Dispensed”, and pumping direction. Use the ‘Rate’,
‘Volume’, and ‘Pumping Direction’ keys to set or review the pumping setup. For continuous pumping, set the
“Volume to be Dispensed” to 0.0 (off). The “Volume to be Delivered” is disabled when the display reads [ off].
8.3.2 ‘FILL’: Fill Function
The Fill function reverses the pumping direction and withdraws or dispenses the volume dispensed or
withdrawn. After a series of arbitrary dispenses, the Fill Function uses the Volume Dispensed to automatcally
refill the syringe. The Volume Dispensed is cleared when the Fill Function begins.
The pumping rate can be set, as with the Rate Function.
Fill at the current dispense/withdraw rate: If the Fill function’s pumpng rate is set to 0.0, the previous function’s
pumping rate will be used for the Fill rate.
8.3.3 ‘InCr’: Increment Rate Function
The increment and decrement functions operate the same as the ‘RATE’ function, except that the
specified rate is added (‘INCR’) or subtracted (‘DECR’) from the current pumping rate. The current pumping rate
when the function is executed is the base pumping rate for the function. If no base pumping rate exists, such as
when executing a pause function or when the Pumping Program is first started, a Program error will occur and the
Program will stop.
The pumping rate units will be the same as the base pumping rate, and therefore cannot be set, nor are they
displayed, with the pumping rate increment or decrement value. As with the ‘RATE’ function, a “Volume to be
Dispensed” and pumping direction can be specified for the increment and decrement functions.
When used within a Program loop, the pumping rate can be incremented or decremented in small step intervals.
