2. Highlight SETPOINT SAMPLING using the up and down arrow soft keys on
the Advanced Options Menu, then press the

SELECT soft key.
4. Highlight either

Note: You must log rainfall to use
set point sampling on a rainfall

flow in order to implement set point
sampling on a flow rate of change. If
you forget, you are reminded when
the program begins.
6. Enter the desired high or low trigger point using the numeric keypad, then
press the
ACCEPT soft key.
7. Enter a Deadband value (see Setting the Deadband on page 121) or, if
programming for Flow Rate Of Change or Rainfall, enter a time interval
within which the flow or rainfall change must take place.
Sample on High Condition and Sample on Low Condition can be enabled at
the same time. There is no limit to the number of sampling triggers that can be
enabled at one time.
