5.13.5 “Dry Period” Option

5.13.6Resetting the Sample Interval at Enable

RESET SAMPLE

INTERVAL AT ENABLE?

YES NO

If you answer “NO” to the above screen, you will see:

CONTINUE COUNTDOWN

WHILE DISABLED?

YES NO

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.

START “EXTENDED 1”

AFTER A 72 HOUR

“DRY” PERIOD?

YES NO

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.
