To repeat the dose
The pump has recorded the number of pumphead revolutions required to dis-
pense the master dose. If the volume of fluid in the measuring vessel is the
volume required, press
START
to repeat the dose.
If the volume of fluid in the measuring vessel differs from the volume required,
the percentage may be adjusted within the limits 1% to 999% of the master
dose. Use the
UP
or
DOWN
keys to alter the percentage. Press
START
to dis-
pense the new dose.
The display counts down as the dose proceeds and stops when the dose is
complete.
If
STOP
is pressed during dosing, the pump stops and returns the user to the
MemoDose percentage screen.
Press the
STOP
key twice within half a second if you wish to exit MemoDose and
return to manual operation.
20.1 Changing dosing speed
The user must exit MemoDose in order to change pump speed (and direction). After
returning to MemoDose, the pump dispenses the previous dose size at the new speed.
Press the
STOP
key twice within half a second. The pump displays the manual
mode main screen.
Do not start the pump. Doing so erases the previously recorded master
dose and replaces it in the pump’s memory with the current, unmea-
sured dose
. Adjust the speed showing on the display using the
UP
or
DOWN
keys.
