This menu enables the user to test the Sample Pump forward and reverse times. Any settings made by the
user in this menu are automatically reset when the user exits this menu.
1. Valve. Valve allows the user to select the stream or manual sample ports the Sample Pump Test is going
to be carried out. The valve selection may have an effect on the Sample Pump forward time measured
with the Pump Forward Test below, unless all sample lines are at the same length.
2. Pump Forward Test.
This function starts the Sample Pump running in the forward direction. When the
sample has been correctly transported to the BioTector, as far as the recommended sample transport
point, or until it drips out into the drain, press ESCAPE. This stops the timer, and provides the user the
correct FORWARD times to be programmed for each stream and manual sample in the Sample Pump
menu (see Section
8.2.2 Sample Pump for details).
3. Pump Reverse Test.
This is the same as the Pump Forward Test above, only this time Sample Pump
operates reverse to empty the sample lines back into the corresponding stream selected with the Valve
above.
5.

Sample Pump. Sample Pump is a link to the Maintenance, Commissioning, Sample Pump menu (see
