Introduction

The Weather/Anemometer Sensor measures

• wind speed,

• air temperature,

• relative humidity, and

• barometric pressure.

From these primary measurements it calculates

012-09911D

Quick Start

1. Connect the Weather/Anemometer Sensor to your PASPORT
interface.

2. If you are using a computer, connect the PASPORT interface
to it and start DataStudio.

• wind gust speed

• dew point

• humidex

• wind chill, and

• absolute humidity.

The sensor connects to a PASPORT interface. If it is a logging
interface (such as Xplorer or Xplorer GLX) in standalone mode,
data are recorded and displayed on the interface itself. If the PAS­PORT interface is connected to a computer, data are recorded and
displayed on the computer in DataStudio.

Set-up

Connect Sensor to Interface

Plug the sensor into any port of your PASPORT interface, either
directly or using the PASPORT extension cable (PS-2500).

Sensor Positioning

• Optional: Screw a 1/4-20 threaded rod (such as CI-9874) or
tripod into the mounting hole on the back of the sensor and
mount it as illustrated (Figure 1).

3. Shield the sensor from direct sunlight.

4. Hold the sensor so that so that air flows into the rear of the

windmill.

5. Press or click the start button to begin recording data.

• Hold (or mount) the sensor vertically so that air flows into
the rear of the windmill (Figure 1).

• Shield the sensor from direct sunlight.
