transpiration reading.
Monthly Evapotranspiration (ET)
Press 2ND then press ET, then repeat the key sequence to display Monthly ET.
Yearly Evapotranspiration (ET)
Press 2ND then press ET, then repeat this key sequence two more times to display the
ET reading since January 1st of the current year.

Lamps
Press 2ND then press LAMPS to turn on the backlight for the screen display.
Press 2ND then LAMPS again to turn the backlight off.
Use the backlight when the LCD is not clearly visible. When the console is
battery operated, the backlight remains on as long as keys are pressed or a ticker tape
message is scrolling across the screen. If no keys are pressed, the backlight automati-
cally turns off about fifteen seconds after it is turned on. If any key is pressed while it is
turned on, it will stay illuminated for 60 seconds from the last key press. When battery
power is low, the backlight does not light.
Note: When the console receives power from the AC adapter, the backlight remains on
until it is toggled off. Leaving the backlight on raises the inside temperature reading
and lowers the inside humidity reading.
