Test the Sensors

Before permanently installing your new sensor, you should test it. To do this, take

your console with you out to your ISS, and follow the instructions below.

On the Vantage Pro2 ISS, open the transmitter shelter. See Opening the

Transmitter Shelter in the Vantage Pro2 ISS Installation manual for more

information.

1. Plug the UV Sensor cable into the receptacle labeled “UV”; plug the Solar

Radiation Sensor into the receptacle labeled “SUN.”

With the sensor in sunlight, hold the sensor body with the white diffuser pointed

upward. Do not touch the diffuser. If you do, clean it after mounting using a

cotton swab and ethyl alcohol. Do not use rubbing alcohol.

2. On the Vantage Pro2 console, press 2ND then UV to see the UV Sensor reading

and 2ND then SOLAR to see the Solar Radiation reading. The dashes should

change to numbers as the sensor reports data. If you still see no reading after

two minutes, reconnect the sensor cable to the ISS, ensuring it is in the proper

receptacle. If you still see no reading, contact Davis Technical Support (see

Technical Support at the back of this manual).

Note: The sensors update every 50 seconds to one minute.

3. Unplug the sensor cables from the sensor interface.

For permanent mounting, unplug the cable from the ISS and follow the

instructions below. The test procedure is complete.

Securing the Sensor on the Shelf

Note: It does not matter which sensor is mounted on the right/left side of the shelf.

1. Remove the rain collector cone from the ISS: turn it counterclockwise until the

latches allow you to lift it up and off.

2. Place the sensor shield onto the sensor

body as shown. Be careful to avoid

touching the diffuser.

3. Route the sensor cable down through one

of the large holes in the mounting shelf.

Place a flat washer over the end of each

screw and insert it through the shield and

body. Place a spring over the end of each

screw and hold the springs in place using

a #6 screw retainer.
