7.10 Adjustment or Calibration

Note: The calibrated value can only be adjusted on the console. The remote sensor(s) always
displays the un-calibrated or measured value.
Note: The measured humidity range is between 10 and 99%. Humidity cannot be accurately
measured outside of this range. Thus, the humidity cannot be calibrated below 10% or above 99%.
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.
The WS-12 supports up to eight remote sensors. Each of the eight sensors can be calibrated.
If you own more than one remote sensor, press the CHANNEL/+ button first to display the
specific channel you wish to calibrate.
