Followed by:
Then:
If you press the right arrow key several times, the following
times will appear:
The intervals above are the periods of time over which the
rainfall occurs. The amount of rain entered in the previous step
and detected by the rain gauge must fall during the time interval
chosen from this menu before the flow meter recognizes the event
as a storm. The next menu defines the interval that must pass
between storm events.
If you select CONDITIONAL for alarm dialout, the following will
appear:
(TEMPERATURE), (RAINFALL), (YSI pH), (YSI DO), (YSI
CONDUCTIVITY), and (YSI TEMP) may also appear. As men-
tioned previously, some of these menu options may not appear,
depending on selections you made earlier in the program. At
least one of the options will be available to you.
D.O., pH, TEMPERATURE, the YSI outputs, and RAINFALL all
require activation in step 1 and connection of the appropriate
sensor to the flow meter. D. O. and pH will never appear
together, as only one can be used at a time. When you have
selected the condition you want, the display will advance to the
following:
For these conditions, you enter an amount which if exceeded
(GREATER THAN), or if dropped below (LESS THAN), or if
changed too quickly (RATE OF CHANGE), will activate the
alarm dialout. For RATE OF CHANGE, you enter two values:
amount and time over which change occurs. Then the
display will advance to the following:
As described for sampler enabling previously, this step allows
you to combine conditions to produce an alarm dialout signal.
Select DONE if you do not need more than one condition to
trigger the alarm.
