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, through the Sample (ARS) Valve and 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.
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 and the oxidized sample catch-pot/cleaning vessel (if
installed) 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.
