meter before you press the start sampling key on the sam-
pler. If you are using the flow meter to detect a storm event
and enable the sampler when the event occurs, the sampler
must be disabled by the flow meter when you press the
start sampling key. If the sampler is not disabled, it will
begin the routine as soon as you press the key. This means
that the flow meter must not detect the enable control con-
ditions. The flow meter will disable a sampler only when
the conditions are not satisfied.
Terminating the Routine – A storm routine will terminate
under the following conditions:
• The sampler completes the routine
• A flow meter disables the sampler when the
enable-control condition is no longer satisfied. Once a
sampler running a storm routine has been disabled,
however, it cannot be re-enabled if control conditions are
satisfied again. You can prevent the sampler from being
disabled by "latching" the sampler enable through the
flow meter's control condition
• The time between flow-paced sample events exceeds the
storm routine's maximum flow interval setting
Manual Samples – Manual sampling is not available during a
storm routine. If you press
routine, the sampler will disregard the key.
Run State Displays – Run state displays for storm routines are
identical to displays used with conventional routines. However,
the displays for the first and second bottle groups will alternate
with each other.
