4.3 Multi-Channel Operation

The WS-0100 supports up to three WH-2C remote thermo-hygrometers (one is included). The optional sensors can be purchased at AmbientWeather.com.

4.3.1 Sensor Initialization

Power up the sensors and console in the following order:

1.Power up the console. Do not touch any of the buttons, as described in Section 2.4.

2.Power up the first remote thermo-hygrometer as described in Section 2.5. Wait until the sensor reports into the console.

3.Power up the second remote thermo-hygrometer as described in Section 2.5. Wait until the sensor reports to the console. The first sensor will be designated as Channel 1 and the second sensor will be designated as Channel 2.

4.Power up the third remote thermo-hygrometer as described in Section 2.5. Wait until the sensor reports to the console. The third sensor will be designated as Channel 3. The display will switch between each sensor until you exit the initialization state by pressing any button.

4.3.2 Sensor Accuracy Note

Verify the temperature values match closely with the console and sensor array in the same location (about 10’ apart). The sensors should be within 4°F (the accuracy is ± 2°F).

Humidity is a particularly difficult parameter to measure. Verify the humidity values match closely with the sensor array in the same location (about 10’ apart). The sensors should be within 10% humidity (the accuracy is ± 5%).

Allow about 30 minutes for both sensors to stabilize.

4.3.3 Viewing the 3 Sensor Channels

To view the 3 sensor channels, select the CH/+ button. The minimum and maximum can be viewed for each channel as specified in Section 4.2.
