4 Headers Select option 4, Headers. The Batch # Selections screen displays. For each option,
enter the desired information and press ENTER. Press ESC to return to the Program
Variables screen.
Note: The Batch # Selections screen displays options for the report header
information. The print field accepts ten characters. Characters can be letters,
numbers, special characters or spaces. The information entered for each selection
prints in the header of each printout. The entries made from this menu are attached to
the active program. Since there are 15 programs, there can be a different set of entries
for each. All are stored in the battery-protected memory and remain until changed via
this menu.
5 Prime Time (peristaltic
pump)
If your system configuration includes the peristaltic pump, use this option to set the
interval the peristaltic pump runs forward, drawing medium into the system, before
the valves open to deliver samples.
Select option 5, Prime Time. Enter a value for the priming time from 1 to 99 seconds
and press ENTER. The Program Variables screen displays.
Note: At a minimum, the prime time should be long enough for medium to be seen
dripping from the return cannulas. In general, the longer the tubing lengths, the
longer the priming time required.
5 Prime Volume (syringe
pump)
If your system configuration includes the syringe pump, use this option to set the
amount of drawn medium necessary to fill the sampling lines of the entire system.
Select option 5, Prime Volume. Enter a value for the priming volume and press
ENTER. The Program Variables screen displays.
Note: At a minimum the prime volume should be large enough for medium to be seen
dripping from the return cannulas. In general, the longer the tubing lengths, the larger
the prime volume required.
6 Purge Time (peristaltic
pump)
If your system configuration includes the peristaltic pump, use this option to set the
interval the peristaltic pump runs in reverse to return the uncollected medium in each
line back into the vessel from which it was drawn.
Select option 6, Purge Time. Enter a value for the purge time from 1 to 99 seconds
and press ENTER. The Program Variables screen displays.
Note: Purging also clears the sampling filters of particulate matter that may restrict
successive samples. As with priming, the longer the tubing lengths, the longer the
purge time required.
