User manual

Note: The purpose of calibration is to fine tune or correct for any sensor error associated with the

devices margin of error. Errors can occur due to electronic variation (example, the temperature sensor

is a resistive thermal device or RTD, the humidity sensor is a capacitance device), mechanical

variation, or degradation (wearing of moving parts, contamination of sensors).

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. The purpose of your weather station is to measure

conditions of your surroundings, which vary significantly from location to location.
