6D. ET & RAIN TABLES
The ET & Rain Table section of the controller allows
you to look at the last consecutive 28 days of ET
and Rain data.
From the REPORTS menu screen (Figure 6.2):
1. Press the ET & RAIN TABLES
Menu key.
The ET & RAIN TABLE screen is displayed
(Figure 6.6).

6D.1 Reports / ET & Rain Table (ET)
The ET Table (Figure 6.6) shows daily ET numbers
(measured in inches) stored in the controller. These
numbers are used to determine the amount of
irrigation to be applied to each station and can be
generated from the following sources:
o Automatically generated by an ET Gage
wired to the controller.
o Automatically generated by a Campbell
Scientific weather station.
o Automatically shared from another controller
connected to an ET Gage using Calsense
Command Center software. (Controllers
must have communication capabilities to
share ET).
o Shared from another controller in an (-FL)
chain.
o Historical ET which is automatically entered
into the ET Table when Daily ET is enabled,
and remains in the table until it is replaced
by real time ET from an ET gage or
manually edited by the user.
o Manually edit the ET Table.
The ET table stores the last 28 days of ET numbers.
In the example in Figure 6.6 the ET table has a
combination of Historical ET, actual real-time ET and
user edited ET. The letter next to each number
indicates how the number got into the ET Table:
h – Historical: This means the (ET) number was
retrieved from the historical (ET) table.
g – ET Gage: This means the (ET) number was
retrieved from an actual real-time (ET) gage.
e – Edited: This means the (ET) number was edited
at the controller by a user.
c – Central: This means the central created the (ET)
value due to the real-time (ET) value being below
the minimum (ET) set by the user.
Prior to irrigation, the controller will read the number
in the ET table and use it to recalculate the irrigation
run times for each station.
6D.2 Reports / ET & Rain Table (Rain)
The Rain Table (Figure 6.6) is where the controller
stores rainfall numbers (measured in inches). The
numbers in this table can be generated from the
following sources:
o Automatically generated by a Rain Bucket
wired to the controller.
o Automatically generated by a Campbell
Scientific weather station.
o Automatically shared from another controller
connected to a Rain Bucket using Calsense
Command Center software. (Controllers
must have communication capabilities to
share rain).
o Shared from another controller in a (-FL)
chain.
o – Original: This value is zero (no usable rain), it
has no effect on irrigation run times.
m – Below minimum: The below minimum value is
measured rain that is not enough to offset irrigation
run times.
r – Usable rain: This value is rain that is used to
offset irrigation run times.
s – Shutdown: This means that irrigation was
stopped due to rain reaching the maximum allowed
and being shared with this controller.
The usable rain in the Rain Table is used to reduce
each stations irrigation run times as determined by
the precipitation rate. It is determined by settings
programmed at the Rain Bucket setup screen at the
controller. When scheduled irrigation is set to occur,
the controller will use up the usable rain first by the
amount of time scheduled to irrigate for each station.
Until the usable rain is used up, there will be no
irrigation. This will continue until all of the rain is
used up at which time the irrigation will start again.
