Operating the 8000 4
8000 Operator’s Manual 49
Following is a description of the Main Menu screen options:
Table 3 Main Menu Options (Apparatus 1 / 2)
Option Function
1 Set Clock/Alarms Use this option to set the clock and alarms. If your system configuration includes
the syringe pump, the start output delay option also displays on this screen. See
“Main Menu Option 1 - Set Clock/Alarms” on page 51.
2 Set DISSO Use this option to set the DISSO parameters. See “Main Menu Option 2 - Set
DISSO” on page 53.
3 Start Output Delay
(peristaltic pump)
If your system configuration includes the peristaltic pump, use this option to set
the delay from the start of a program until the TTL signal is sent from the START
OUTPUT jack on the 8000 rear panel.
Select option 3, Start Output Delay. Enter a delay length of up to 99:59 minutes
for the 8000 TTL output and press ENTER. The Main Menu displays.
Note: This output signal can be used to start other instrumentation, such as a
dissolution apparatus, after the program on the 8000 is started. The default delay
is 00:00, indicating that the signal will be sent at the moment a program starts.
For example, a value of 10:00 delays the signal for ten minutes after the program
starts. Set the value to 00:00 to eliminate the delay feature.
When the syringe pump is enabled, Start Output Delay displays under the Set
Clock and Alarms screen as option 6. See “6 Start Output Delay” on page 52.
3 Set Syringe Pump
(syringe pump)
If your system configuration includes the syringe pump, use this option to set the
syringe pump parameters. See “Main Menu Option 3 - Set Syringe Pump” on
page 55.
4 Manual 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 4, Manual Prime Time. Enter a value for the priming time from 1 to
99 seconds and press ENTER. The Main Menu displays.
Note: At a minimum, the manual 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. This value is not used by sampling
programs, which have their own individual priming time values. It is used only
with the MANUAL SAMPLE, CAL, and CLEAN SYSTEM keys on the 8000.
