Rainfall
Rainfall CAL determines how much rainfall each increment (pulse) represents.
The default rainfall CAL of 100 works for a 0.01” increment.
Calibrated Rainfall= # of pulses * (1/CAL)
If you use a rain collector which measures in a different increment, or if you
wish to display rainfall in a unit of measure other than the rain collector’s
native unit of measure, consult the table below to determine the correct calibra-
tion number for your purposes.
Note: Rainfall CAL must be a whole integer (no decimals). Generally, if the Energy EM is set to display rain-
fall in a unit of measure other than the rain collector’s “native” unit of measure, you would be
required to enter a CAL number which was not a whole integer. Therefore, we STRONGLY advise you
to always set your Energy EM to display the rain collector’s native unit of measure before entering,
changing, or viewing rainfall CAL. Failure to do so may result in inaccurate rainfall readings. Be
aware, however, that so long as you have the correct rainfall CAL for your rain collector, the
Energy EM will accurately convert rainfall amounts from inches to millimeters (and vice versa.
Changing Calibration Numbers
1. Press the appropriate function key as necessary to display the reading for which you
wish to change the CAL. Hold down the function key after pressing it for the final time.
For example, if you want to change the CAL for inside temperature, press
TEMP until the wind chill appears. Then press and hold TEMP to display
inside temperature. After holding the function key for approximately three
seconds, the word CAL begins to alternate in the display with the reading.
After a few more seconds, the current calibration number appears.
2. Use ENTER to set CAL.
See “Entering Negative Numbers” on page 16 for instructions on entering a
negative CAL number.
3. When finished, press any function key to save the new CAL and exit the calibration
display.
