3. If the liquid detector is disabled, the GLS
will ask for a manual or “fixed” suction head
since it will not be able to calculate the
head.
4. Check the sample volume. This process
deposits the programmed sample volume
into a container so you can measure the
delivered volume. You can then enter the
actual volume delivered to refine the GLS
pump tables. To continue, select YES.
5. The GLS waits while you prepare to collect
a sample. To prepare, pull the lower pump
tube from the bulkhead fitting. Hold the end
of the tube over an empty graduated
cylinder, such as Isco’s 1,000 ml plastic
graduated cylinder, P/N 299-0020-00. Press
the Enter button when you are ready.
