5.5 Adjustment or Calibration 

Note: 

The calibrated value can only be adjusted on the console.   

 
The purpose  of  calibration is to  fine tune or  correct  for any  sensor  error  associated with the devices 
margin of error. The measurement can be adjusted from the console to calibrate to a known source. 
 
Calibration is only useful if you have a known calibrated source you can compare it against, and is 
optional. This section discusses practices, procedures and sources for sensor calibration to reduce 
manufacturing and degradation errors. Do not compare your readings obtained from sources such as 
the internet, radio, television or newspapers. They are in a different location and typically update once 
per hour. 
 
The purpose of your weather station is to measure conditions of your surroundings, which vary 
significantly from location to location. 

        5.5.1 Indoor Temperature Calibration 

 
To  enter  the  indoor temperature  calibration  mode, press and hold the 

SET/ADJUST and  CLEAR/-

 

buttons  at  the  same  time  for  3  seconds  and  the  temperature  value  will  begin  flashing.  Press  the 

[+]

 

button  to  increase  the  temperature  and  the 

CLEAR/-

  button  to  decrease  the  temperature  reading  in 

0.1°  increments.  To  rapidly  increase  (or  decrease)  the  humidity  reading,  press  and  hold  the 

[+]

  or 

CLEAR/-

 button. 

 
To return the temperature to the actual or uncalibrated measurement, press the 

ADJUST

 button. 

 
Once the displayed temperature equals the calibrated source, press and hold the 

ADJUST 

button for 

three seconds, or wait 15 seconds for timeout, and the humidity value will stop flashing. 
 

5.5.2 Outdoor Temperature Calibration 

To enter the outdoor temperature calibration mode, press and hold the 

SET/ADJUST and [+] 

buttons 

at the same time for 3 seconds and the temperature value will begin flashing. Press the

increase  the  temperature  and  the 

CLEAR/-

  button  to  decrease  the  temperature  reading  in  0.1° 

increments.  To  rapidly  increase  (or  decrease)  the  temperature  reading,  press  and  hold  the 

[+]

  or 

CLEAR/-

 button. 

 
To return the temperature to the actual or uncalibrated measurement, press the 

ADJUST

 button. 

 
Once the displayed temperature equals the calibrated source, press and hold the 

ADJUST 

button for 

three seconds, or wait 15 seconds for timeout, and the temperature value will stop flashing. 
 

Discussion

:

 

Temperature errors can occur when a sensor is placed too close to a heat source (such 

as a computer or TV or in a window). 
 
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial) 
and other digital thermometers are not a good source and have their own margin of error.
