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-11 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.

5.9.1 Temperature Calibration

In normal mode, press and hold the SET and CHANNEL/+ keys at the same time for five

seconds to enter the temperature calibration mode. The indoor temperature will begin flashing.

Press the [+] or [-] key to increase or decrease the temperature reading (in increments of 0.1).

Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly.

Press the ALARM key to reset current value.

Press the SET key switch to next channel (1through 8). If no operation is performed, the

calibration mode will timeout in 30 seconds.

5.9.2 Setting Calibrated Humidity

In normal mode, press and hold the SET and HISTORY/- keys at the same time for five seconds

to enter the humidity calibration mode. The indoor humidity will begin flashing.

Press the [+] or [-] key to increase or decrease the humidity reading (in increments of 1%). Press

and hold the [+] or [-] key for three seconds to increase or decrease rapidly.

Press the ALARM key to reset current value.

Press the SET key switch to next channel (1through 8). If no operation is performed, the

calibration mode will timeout in 30 seconds.

Note: Humidity is a difficult parameter to measure accurately and drifts over time. The
