Variable time or flow intervals can be set for sample cycles.
Intervals will be in hours and minutes if the sample pacing mode is
time based. intervals will be in counts if the sample pacing mode is
flow based.
Procedure:
1. Select PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING
from the main menu.
2. Select VARIABLE INTVL>ENABLE.
3. Enter the time (or count) interval between each sample cycle.
Up to 99 intervals can be entered.
Note: When entering individual intervals the current interval Is recorded
when the enter key is pressed.
The timed bottle option allows a single sampler unit to function like
multiple samplers. This can be useful in situations such as high flow
versus low flow days.
In this mode, the user configures the sampler to execute a sampling
program in multiple parts. The first part of the program executes for
a time interval defined by the operator. The second part then
operates for a user defined time interval, followed by the third part,
and so on.
The sample bottles are also divided into multiple sets. The first set
of bottles la assigned to part ono of the sampling program. The
second set of bottles is assigned to part two of the sampling
program, and so on. .
A timed bottle program can run at the same time as the storm
program, setpoint sampling; and variable intervals,
The timed bottle function, when enabled with variable intervals, will
collect samples in each timed bottle set according to the variable
intervals defined. When a timed bottle set switch occurs upon
expiration of the trigger time, the variable interval index is reset.
Note: Timed bottle can bo enabled only if the sampler is configured with
multiple bottles, non -composite mode, and the distrituttian mode is sot fo
Bottles/Sample.
