15.4 Dose
The Dose facility programs the pump to dispense measured volumes of fluid. These
can be individual doses, a batch of doses delivered singly, or a batch of doses deliv-
ered at timed intervals. A dose, or batch of doses, can be controlled by the pump, by
pressing the START key, or by pressing an optional remote-control foot or hand
switch or by an external logic signal.
You can start pumping immediately using the settings chosen for the previous batch;
or you can alter one or more of the settings before starting to pump.
To start pumping immediately:
Use the UP and DOWN keys to select Dose from the main menu. Press RE-
TURN. The pump displays the dose size, dosing interval and the number of
doses and waits for the START key to be pressed.
When the START key is pressed, the pump offers the user the opportunity to
prime the pump. To do so, press and hold the START key. The pump operates
continuously at maximum speed until the START key is released.
When priming is complete, or if no priming is required, press RETURN. The
pump displays the dose size and the number of doses and waits for the START
key to be pressed to start the batch.
To alter the batch settings before starting pumping:
Use the UP and DOWN keys to select Dose from the main menu. Press RE-
TURN.
The pump displays the first three of the eight parameters which may be set for
the next dosing session: dose volume, dosing interval and number of doses.
