5 After 30 seconds press the Up button.
6 Measure the water remaining in the cylinder, and calculate the flow rate.
7 Park the sample probe.
NOTE:
When properly adjusted the tension on the bottom three peristaltic pump
tubes (channels 1-3) should be the same and the tension screw for the top
pump tube (reagent tube, channel 1) should be screwed in 1 to 2 mm farther
than the other channels.
Once the clamp tension on the pump tubing is established, relieve their
stretch:
8 Unclamp reagent and sample clamps.
9 Park the sample probe.
10 Press the Up button to remove the sample probe from the rinse station.
11 Remove the reagent uptake tube from the SnCl 2.
12 Allow the waste tube to empty.
13 Unclamp waste tube clamps.
14 Turn the pump off using the software controls.
Do not leave tubes clamped in place when the system is not being used. The
next time the system is used, hook the tubes and close the quick-release
mechanisms. No screw adjustments will be needed. Previous clamp tension is
“remembered” as the quick release is engaged and disengaged.
