10-94
Using the LI-8150 Multiplexer
For example, you could specify a 90 second Obs. Length, 45 second Deadband,
Pre-purge of 2 minutes, and Obs. Count of 3. This protocol could then be repeated
every hour for 240 hours (10 days). The resulting data set would include 240
measurements, with each measurement consisting of three 90-second observations
on the chosen port. The maximum number of repeats is 12000 (Indefinitely (Max
Times) button).
You can elect to turn off the multiplexer pump between repeated measurements to
conserve power and extend the life of the pump, by enabling ‘Flow Off Between
Repeats’.
Choose a location (Internal Flash or Compact Flash Card) to which to log data; note
that data files created with the Multiplexer can become quite large. For this reason,
we recommend that you log to Compact Flash, as the internal memory is limited.
