Overview

This Quick Reference Guide contains information that is needed to install
WMT700 with the FIX70 mounting kit.

Unpacking Instructions

When unpacking the wind sensor, remove the transportation damper that
protects the sensor body. To avoid bending or twisting the array, do not remove
the damper protecting the array until you have installed WMT700. The figure
below shows the damper protecting the array.

NOTE

Remove the transportation damper for the array before you switch on the
power supply.

www.vaisala.com/wmt700.

CAUTION

VAISALA

________________________________________________________________________ 3

When handling WMT700, do not rotate, pull, strike, bend, scrape, or
touch the transducers with sharp objects. Any impact on the wind sensor
array damages the device.

QUICK REFERENCE GUIDE _________________________________________________________

Selecting Location for Representative Measurements

Finding a suitable site for WMT700 is important for getting representative
measurements. The site should represent the general area of interest. It is
recommended that you follow the WMO Guide to Meteorological Instruments
and Methods of Observation WMO-No. 8.

Mounting

When mounting on a vertical pole mast, WMT700 can be placed either on the
side or on top of the mast. The figure below shows the mounting options for a
vertical mast.

When mounting WMT700 on a cross arm, the wind sensor can be placed with
the array facing up or down. The following figure shows WMT700 installed
with the array facing up. If the wind sensor is installed with the array facing
down, refer to section Configuration Parameters in the User's Guide.

Aligning

Powering

WMT700 is permanently marked with the letter N and a north arrow. WMT700
needs to be aligned in such a way that this arrow points to the north and the N-S
transducers are in line with each other. Misaligning WMT700 causes a wind
direction offset error in the measurement results. If mechanical alignment of
WMT700 cannot be done, you can correct the wind direction offset error using
an offset adjustment command. Refer to section Alignment Tuning in the User's
Guide.

WMT700 can be used with any general power supply of 9 ... 36 V that meets
the applicable safety regulations. Connect the heating supply wires to the
ground in case heating is not used. The table below lists the power supply
requirements.

Operating WMT700

The table below lists the operating commands when the WMT700 protocol is
selected.

Command Description

$aMEAS Starts wind measurement. The duration of the

measurement is based on the user-configurable

averaging time.
$aOPEN Switches the serial port to the configuration mode.
$aPOLL,y Fetches data from WMT700.
$aSLEEP Switches WMT700 from the normal operating mode to

the low-power mode.

Présentation

Ce Guide de référence rapide contient des informations nécessaires
à l’installation du WMT700 avec le kit de montage FIX70.

Vous pouvez télécharger le Manuel de l’utilisateur complet à l’adresse
suivante :

Instructions de déballage

Pour déballer le capteur de vent, retirez l'amortisseur de transport qui protège le
corps du capteur. Pour éviter de plier ou de tordre le réseau d’antennes, ne
retirez pas l'amortisseur de protection de transducteurs à ultrason avant d'avoir
installé le WMT700. La figure ci-dessous représente l'amortisseur de protection
de transducteurs à ultrason.

www.vaisala.com/wmt700.

REMARQUE

Retirez l’amortisseur de protection de transducteurs à ultrason avant de
mettre le capteur sous tension.

ATTENTION

8

___________________________________________________________________ M211218EN-B

Lorsque vous manipulez le capteur WMT700, évitez de tourner, tirer,
heurter, plier, érafler ou toucher les transducteurs avec des objets pointus.
Le moindre impact sur le positionnement des transducteurs du capteur de
vent peut endommager l'appareil.

_________________________________________________________________________ Français

Sélection d’un emplacement pour les mesures représentatives

Pour obtenir des mesures représentatives, il est important de trouver un site
adéquat pour le WMT700. Ce site doit être représentatif de l’ensemble de la
zone d’intérêt. Nous vous recommandons de suivre le Guide des instruments et
des méthodes d'observation météorologiques OMM-N° 8.

Montage

Sur un mât vertical, le WMT700 peut être monté sur le côté ou sur le dessus. La
figure ci-dessous représente les options de montage sur un mât vertical.

VAISALA

Si vous montez le WMT700 sur une traverse, le capteur de vent peut être placé
avec les transducteurs vers le haut ou vers le bas. La figure suivante montre le
WMT700 installé avec les transducteurs orientés vers le haut. Si le capteur de
vent est installé avec les transducteurs orientés vers le bas, reportez-vous à la
section Paramètres de configuration dans le Manuel de l’utilisateur.
