15.4.3 Number of doses
Use the UP and DOWN keys to highlight the dose number line of the display
(the third line, first screen). The display shows the previously set number of
doses.
If the number displayed is correct, do nothing. UP and DOWN highlight the
next or previous parameter.
If you wish to change the number of doses, press RETURN and use the UP and
DOWN keys to scroll the display to the required number. Example figures are
shown here. To quickly return to the starting value, press STOP. When the
number is correct, press RETURN. The first screen of the dose menu is redis-
played with the new number of doses. If you wish to change other parameters,
use the UP and DOWN keys to highlight each as required.
Note: If the number of doses is set to 1, the pump waits for a press on START
for each dose, and the display during dosing increments with each dose. If the
number of doses is set to greater than 1, the display decrements with each dose
until it reads zero and the batch is complete
.
15.4.4 Pump speed
Use the UP and DOWN keys to highlight the speed line of the display (the first
line, second screen). The display shows the previously set pump speed.
If the speed displayed is correct, do nothing. UP and DOWN will highlight the
next or previous parameter.
If you wish to change the speed, press RETURN and use the UP and DOWN
keys to scroll the display to the required speed, up to a maximum of 300 rpm
(low-speed model or highspeed model fitted with a 314 pumphead) or 400 rpm
(high-speed model fitted with a 313 pumphead). Example figures are shown
here. To quickly return to the starting value, press STOP. When the speed is
correct, press RETURN. The second screen of the dose menu is redisplayed
with the new pump speed. If you wish to change other parameters, use the UP
and DOWN keys to highlight each as required.
