4.13 Operating the Pump You can manually operate the sampler’s pump in the forward or
reverse direction. You can do this to test the pump, draw a large
sample, or purge the suction line.
When you run the pump manually, the sampler reports the
number of pump counts during the pump’s operation. Use this
feature to obtain an estimate of the pump counts required to
purge a nonstandard suction line.
You can also manually run the pump from the main menu. Press
the “1” key and then to run the pump in reverse. Press the “3”
key and then to run the pump forward.
