2)
The display moves to RATE, permitting a change if required. Use the numerical
keypad and
enter
to make changes (or leave unchanged). The pump
immediately changes to the new flowrate, if changed, and the volume
continues to increment, uninterrupted by the review process, to new target
dispense volume when it will stop automatically.
Note:
If the volume is changed to a volume
smaller
than the volume already accumu-
lated then the pump will stop as soon as the new, smaller target volume is entered.
MODE SELECTION
Mode selection is available only on infusion/withdrawal models.
Select MODE from the main menu and then scroll through the options displayed and
select
the mode required.
Possible modes are:
infusion, withdrawal, infusion / withdrawal,
withdrawal / infusion, continuous
Note:
for bi-directional modes a volume is required.
infusion
Pump infuses at the set rate and stops automatically when the target volume is reached.
The pump can be manually stopped and restarted at any time, that is, the dispense is
paused and, when restarted will continue to the set dispense volume.
withdrawal
Pump withdraws at the set rate to the set volume.
infusion / withdrawal
The pump first infuses and when the target volume is reached it immediately changes
direction and withdraws. The volume settings for infusion and withdrawal can be differ-
ent, as can the infusion and withdrawal flow rates.
withdrawal / infusion
The pump runs first in the withdrawal direction and then automatically changes to the infu-
sion direction. Different settings of rate and volume for withdraw and infuse are permitted.
continuous
The pump first infuses and then withdraws, and then cycles continuously. Only one vol-
ume setting for infusion and withdrawal is permitted. If the pump is matched to a valve,
which is actuated by a TTL pulse from the pump, this mode can be used to infuse and
then refill the pump for continuous operation.
The menu now prompts for volume and rate settings relevant to the mode selected.
