interval will be reset at the enable time. Samples at disable do
not affect the sample intervals. Standard programs do not take a
sample at the enable time.
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 opportunity to suspend the start of sam-
pling. This choice is useful for storm programs that require a
flow-paced sample taken after the initial grab sample.
“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.
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. Furthermore, 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.
