5.13.4 Delay To Start Of
Sampling
If you have selected ONCE ENABLED STAY ENABLED and
have chosen to not sample at the enable, you have the oppor-
tunity to suspend the start of sampling. This choice is useful for
storm programs that require a flow-paced sample taken after the
initial grab sample.
5.13.5 “Dry Period” Option For samplers used with a 0.01 inch tip rain gauge, you can cause
the sampler to wait for a “dry” period of under 0.10 inches of rain
over a 72-hour period before running the program. At RUN time,
the sampler asks if you want to restart the 72-hour period. Select
this choice if you want the sampler to disregard any “dry” period
that took place prior to the program start. The sampler will wait
for up to one year for the “dry” period to occur.
5.13.6 Resetting the Sample
Interval at Enable
You may want the pacing countdown to start over each time the
sampler becomes enabled. To accomplish this, select “YES” when
asked if you want to reset the sample interval at enable. The next
sample event will occur at the end of a full interval. Fur-
thermore, if the sampler is enabled several times during the
program, it resets the countdown each time.
Use the reset-interval feature carefully. For example, avoid
resetting the interval when you sample with uniform-time
pacing and want to take samples at specific times.
The effects of resetting the interval can be seen in this example:
A sampler has been programmed to sample every 15 minutes and
to reset the interval when enabled. It receives an enable signal at
10:03 and takes a sample. After resetting the interval, the
sampler takes subsequent samples at 10:18 (not 10:15), 10:33
(not 10:30), and so on.
If you select “NO” when asked if you want to reset the sample
interval at enable, you will be asked if you want to continue the
countdown while disabled. You can have the sampler continue
the countdown, repeating it as often as necessary while the
sampler is disabled, or you may suspend the countdown while
disabled, resuming the countdown as the sampler is enabled. The
standard program allows the countdown to continue while dis-
abled.
