When rain rate is off, term rain is substituted.

Min/Max, when selected outputs at midnight the minimum and maximum value for the day. The report function must be on in order for the output to occur. This function must also be on if you want the minimum and maximum to be logged to memory.

Form Feed, when selected sends a form-feed character at midnight, which is normally desirable if a printer is directly hook up to the RS-232 interface.

Rainfall rate, when selected outputs rainfall rate instead of term rain in the report function.

Lunar Tide Cycle

The lunar tide cycle function may be set to display the position of the moon in relation to its revolution around the earth. The moon's position is the primary, although not the only, factor in predicting high and low coastal tides. High tides are generally present when the moon is overhead or when the moon is 180 degrees from overhead. Low tide is generally present when the moon is in the 90 degree or the 270 degree position. This method of predicting tide works well on the West and East coasts. On the Gulf coast, this method is not as successful.

To set the tide clock, follow the directions in the time set function. The first item to be entered is the tide cycle duration. The tide cycle duration may be set from 1 to 99 hours. Twelve hours and fifty one minutes is the normal number for a tide clock. The second item to be entered is the time of the high tide. This information is generally found in the newspaper. If predicting the tide does not apply
