4.4 Pacing
Sample pacing is the rate at which the sampler takes samples.
Depending on the type of pacing you select, the rate is controlled
by the sampler’s internal clock or by inputs received from con -
nected instruments.
Standard programming provides time pacing and flow pacing
(refer to Step 7 in the previous programming example). When
programming, you will be asked to select time or flow paced sam-
pling. Depending upon your choice, you will see one of the fol-
lowing screens:
4.4.1 Time Pacing
In time-paced sampling, the interval between samples is a con-
stant time interval. When you program the sampler for time
pacing, the sampler prompts you to enter the time between
sample events in hours and minutes. Time paced programs
always take a sample at the start time.
4.4.2 Flow Pacing
Flow paced sampling requires a flow meter, flow logger, or a 700
Series flow module. A flow meter or flow logger paces a sampler
by sending an electronic signal to the sampler after measuring a
specified volume of liquid. Because each pulse represents a
volume interval, flow pacing rates are proportional to the volume
of water flowing through the channel.

13. Select CLOCK TIME.
14. Enter 6, then enter 0. This is the clock time at
which the sampler will start the pacing countdown.
15. Select MO, WE, and FR.
Use the arrow keys and

to select the days. When
the correct days are blinking, select DONE and
press

.
16. Enter 48. This setting will stop the sampler after 48
hours. The program may stop sooner if all bottles
are full.
