User's Manual

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.
