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 soil temperature, press
TEMP until the air temperature appears. Then press and hold TEMP to dis-
play soil 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 18 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.
Resetting Calibration Numbers to Default
To completely reset all calibration numbers to their default settings, follow the
procedure below to completely remove power from and then restart the sta-
tion. When the station restarts, all default calibration values are restored.
Note: This resets all station information including highs/lows, barometric pressure, total rainfall, UV period
information, etc.
1. Write down the total rainfall, barometric pressure, and all alarm settings. You will
need to reenter these values later.
2. If desired, write down all highs, lows, daily rainfall, and period information. These val-
ues will be lost and cannot be restored.
3. Disconnect all power sources from the station, including the power adapter, battery
backup, solar power, etc.
All power must be removed from the unit.
4. Reattach the power adapter and insert the battery.
The unit will start up again and all CAL numbers will be reset to their
default values.
5. Re-enter the total rainfall, barometric pressure, and all alarm settings.
