5.4 Reset Max/Min
To reset the Max/Min values, press and hold the
CLEAR/-
button for 3 seconds.
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
[+]
button to
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.
