Testing the Anemometer

Weather Monitor II Page 9

3. TESTING THE STATION

Before doing anything else, test the station in your living room or workshop. If

you have purchased the optional rain collector or additional sensors, now is

the time to assemble and test these using the appropriate manual. Consult the

Troubleshooting Guide on page 39, or the guides in the respective manuals, if

you experience any difﬁculty.

Note: You should test each external sensor without extension cables ﬁrst, and then repeat the test with

extension cables. In this way, you can be reasonably sure whether any problems are the fault of the

extension cables or the external sensor itself.

TESTING THE ANEMOMETER

Before you install the anemometer, make sure that the wind speed and wind

direction sensors are functioning correctly.

1. Insert the cable plug at the end of the anemometer cable into the jack marked WIND

on the junction box.

2. Test your assembly by spinning the wind cups.

You should get a speed reading other than 0 on the compass rose in the console

display. If you do not, loosen the set screw and move the wind cups slightly up

or down on the shaft until you get a reading other than 0. Once you are getting a

reading, use the allen wrench provided to tighten the set screw on the side of the

wind cups. Do not over-tighten.

3. Turn the wind direction shaft (the larger of the two stainless steel shafts on the con-

trol head) with your ﬁngers.

Check that the direction readings change on the compass rose in the console dis-

play.

TESTING THE EXTERNAL TEMPERATURE SENSOR

Be sure you get a reading from the external temperature sensor as well. Or, if

you have purchased the optional External Temperature/Humidity Sensor, be

sure to test both the temperature and the humidity readings at this time.

To Test the Temperature Sensor

1. Insert the cable plug at the end of the external temperature sensor into the jack

marked TEMP on the junction box.

2. Press TEMP.

A temperature reading and the words INSIDE and TEMPERATURE should

appear on the display.

3. Press TEMP again.

A temperature reading and the words OUTSIDE and TEMPERATURE should

appear on the display.
