Programming Delayed and Intermittent
Sampling
To enter Delayed Start Mode:

the number of minutes delay (up
to 9999) before the sampling
period begins by pressing Digit
Select and Digit Set. Digit Select
advances the fl ashing digit and
Digit Set increases the value of the
fl ashing digit.
To enter Sample Period Mode:
Press Mode. Press Digit Select
and Digit Set to enter the sampling
time period in minutes (up to
9999). Note: The sample period is
the total period in which sampling
is performed and not the pump run
time.
To enter Pump Period Mode:
Press Mode. This is the actual
running time of the pump. Use
Digit Select and Digit Set to enter
the pump run time in minutes (up
to 9999).
Intermittent Sampling Options:
Option 1 - Sample Period and
Pump Period Both > 10 Minutes
Ensure the Sample Period and Pump Period are set to be greater
than 10 minutes. Set the Pump Period for less time than the
Sample Period to initiate intermittent sampling. The pump will
automatically calculate pump “off” time and run 10 equal cycles
of “on” and “off” over the sampling period beginning with the
fi rst “on” time. Delayed start may be used with this option.
Option 2 - Sample Period and Pump Period Both < 10 Minutes
Ensure the Sample Period and Pump Period are set to be less than
10 minutes. The minimum “on” or “off” time setting is one minute.
