3700 Portable Samplers
Section 3 Programming Guidelines
3-76
For example, if the delay to the first group were 0 and the routine
required two timed sample events at 30-minute intervals, the
sampler would take 30 minutes to fill the first bottle group. The
first sample event would occur after the programmed delay to
group sample; the second sample event would occur 30 minutes
later.
Use Display #24 to enter the time interval for the second bottle
group. You can use any interval; you do not have to use the same
time interval for the second bottle group that you used for the
first group.
Flow-Pacing for the second bottle group – I f y o u n e e d a
flow-paced sample for the second bottle group, select “FLOW”
from Display #14. Three flow pacing displays (#16, #22, and
#110) will follow.
Use Display #16 to determine when the sampler will begin filling
the second bottle group. Select “DURING” if you want the second
bottle group filled during the same time period as the first bottle
group.
Select “AFTER” to begin the flow pacing for the second bottle
group after the sampler fills the first bottle group. If you select
“DURING,” the sampler will begin counting flow pulses when it
begins timing the delay to first group sample. The sampler will
take the first sample of the second bottle group as soon at it
counts a full flow-pulse interval. If you select “AFTER,” the
sampler will begin counting flow pulses after the last sample
event of the first bottle group. Use Display #22 to enter the
flow-pulse interval for the second bottle group.
The third flow paced display allows you to enter the maximum
flow interval. The acceptable range of values for the maximum
flow interval is one minute to 99 hours and 59 minutes.
The sampler will terminate the sampling routine when the
amount of time between flow-paced samples exceeds the limit set
for the maximum flow interval. The maximum flow interval will
terminate the routine even if all bottles of either bottle group
have not been filled. Once the sampler terminates a routine, the
sampler cannot be reenabled by the flow meter should the flow
meter detect enable control conditions again.
Note: If the second bottle group requires flow-paced samples, the
sampler may fill the second bottle group before it fills the first
bottle group. This can occur when the flow rate monitored by the
flow meter is higher than anticipated and the flow pulse interval
