Temperature Calibration
In normal mode, press and hold the SET and C keys at the same time for five
seconds to enter the temperature calibration mode. The indoor temperature will begin
flashing. Press the [+] or [-] key to increase or decrease the temperature reading (in in
-
crements of 0.1). Press and hold the [+] or [-] key for three seconds to increase or decre-
ase rapidly. Press the ALARM key to reset current value. Press the SET key switch to next
channel (1through 8). If no operation is performed, the calibration mode will timeout in 30
seconds.
Setting Calibrated Humidity
In normal mode, press and hold the SET and HISTORY/- keys at the same time for five
seconds to enter the humidity calibration mode. The indoor humidity will begin flashing.
Press the [+] or [-] key to increase or decrease the humidity reading (in increments of 1%).
Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly. Press the
ALARM key to reset current value. Press the SET key switch to next channel (1through 8).
If no operation is performed, the calibration mode will timeout in 30 seconds.
NOTE: Humidity is a difficult parameter to measure accurately and drifts over time. The
calibration feature allows you to zero out this error. To calibrate humidity, you will need
an accurate source, such as a sling psychrometer or Humidipaks One Step Calibration kit.
Setting Calibrated wind speed and Rainfall
In normal mode, press and hold the SET and ALARM keys at the same time for five seconds
to enter the wind speed and rainfall calibration mode. The indoor wind speed will begin
flashing. Press the [+] or [-] key to increase or decrease the wind speed reading. Press and
hold the [+] or [-] key for three seconds to increase or decrease rapidly. Press the ALARM
key to reset current value. Press the SET key switch to rainfall calibration. If no operation
is performed, the calibration mode will timeout in 30 seconds.
1. Wind Speed (Gust) Calibration
After entering the Calibration Mode, the Wind Speed Calibration value will begin flashing
(the default is 1.0). Press the [+] or [-] button to adjust the wind speed calibration factor
from 0.75 to 1.25, where:
Calibrated Wind Speed = Calibration factor x Measured Wind Speed
NOTE: The wind gust is also affected by the wind speed calibration factor. Wind speed and
wind gust are adversely affected by installation constraints. The rule of thumb is to install
the weather station four times the distance of the height of the tallest obstruction (for ex-
ample, a 6 m house would require an installation 24 m away).
