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 CONDITION from SAMPLER ENABLE, the fol-

lowing will appear:

(TEMPERATURE), (RAINFALL), (YSI pH), (YSI DO), (YSI

CONDUCTIVITY) and (YSI TEMP) may also appear.

The above conditions are all shown in parentheses, because they

may not be available to you by the time you reach this menu. The

menus that do appear will depend on programming selections

made earlier in the program. At least one of the conditions will

be available to you. If you select LEVEL from CONDITION the

following will appear:

After you select one of these options, the flow meter will request

that you enter a value, for example if you selected GREATER

THAN:

Enter a maximum value for the selected condition, which if

exceeded, will enable the sampler. If you select LESS THAN, the

flow meter will ask you to enter a minimum value for the

selected condition. If the condition falls below that value later,

the flow meter will enable the sampler.

If you select RATE OF CHANGE, the flow meter will ask you to

enter two values, one for the condition, and the other for a period

of time over which the change occurs.

After you have determined what condition will signal the

sampler and under what circumstances, the following menu will

appear:

This step allows you to trigger the sampler from a single con-

dition or from two conditions. Suppose you wanted to trigger the

sampler from only one condition and that condition was level.

You would select level as the condition, and then identify what

change in level would be the trigger. Then you would select

DONE for the SELECT OPERATOR step. Selection of DONE

will advance the flow meter to the next program step. Selection of

OR or AND will allow you to select another condition, and then
