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.
Note
: To retain the MemoDose value through a power interruption the pump must
be in auto-restart mode. The dosing cycle will resume at the start of a dose and wait
for
START
to be pressed, with the MemoDose percentage screen displayed. See
18.12
Auto-restart
.
Press the
STOP
key twice within half a second if you wish to exit MemoDose and
return to manual operation.
