8.8RFreceivingsignalprompt
In normal mode, the signal is interfered by many factors. When there is no signal, the signal is not connected to
the base station. The signal is from no signal to weak signal to good signal, as shown: weak signal
and
good signal

8.9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 FT0213 supports up to eight remote sensors. Each of the eight sensors can be calibrated.
