Introduction
The Marine Anemometer AM706 is a combined instrument for wind speed
and wind direction. It can measure relative wind speed (accuracy ±5%),
relative wind direction (display accuracy 10 °, output accuracy ±1 °). With
inputting GPS (RMC) data, user can choose heading, true wind, or gust
mode.
System composition
The AM706 includes Operator unit and Sensor unit.
Operator unit
Red ring of 36 LEDs show relative wind direction, yellow ring of 36 LEDs
show wind direction variation
The first line 3 digital LEDs show relative/true (True wind mode is selected)
wind speed
The second line 3 digital LEDs show Heading/True wind direction (True wind
mode is selected)/Max relative wind speed in interval time (Gust mode is
selected).
Sensor unit
Wind speed sensor
Wind speed sensor has a rotor with three wind cups
Wind direction sensor
Wind direction sensor has a wind vane to drive an absolute angle sensor unit
Junction box
Consist of waterproof junction box and sensor unit transmitter

Instruction
Theory description
The wind speed sensor has a rotor with three wind cups which spins as the
wind moves past the boat. The Wind speed sensor measures how fast the
rotor is spinning to calculate the wind speed.
The wind direction sensor has a wind vane which points in the direction that
the wind is coming from. The wind direction sensor electronically senses the
direction the wind vane is pointing.
With inputting GPS (RMC) data, user can choose heading, true wind mode,
or gust mode. If precise true wind speed and direction information are needed,
please input GYRO（HDT）and SPEEDLOG（VHW）through NMEA0183
concentrator (NMEA912) .

Maintenance
Operator unit
The unit is maintenance-free.
Clean the operator unit with a damp cloth or mild detergent. Avoid abrasive
cleaners, petrol or other solvents.
Do not allow water to leak into the unit.
Sensor unit
Check the sensor unit, installation bolts and cable periodically.

Installation 安装说明
Operator unit
The unit can be mounted on panel, table, wall or ceiling.
1. For table, wall or ceiling mounting use the supplied bracket from NINGLU.
2. For panel flush mounting, take off the bracket and the front frame.
Cut a 169x169mm size square window in the panel, fix the inside 4 holes
with self-tapping screws, and put on the front frame again.

Wind vane and wind cups assembly
Put the wind vane at the top of the bracket, install as the following order:
black O-ring, flat washer, spring washer, two nuts, one cotter pin. The two
nuts must be screwed tightly and cotter pin locked.
Put the wind cups at the bottom of the bracket, then install as the following
order: flat washer, spring washer, two nuts, one cotter pin. The two nuts must
be screwed tightly and cotter pin locked.

Installation
Sensor unit installation
Ensure that the sensor unit is mounted high enough to avoid any
interference from obstacle. The fixed pillar/pipe diameter should be 60mm
and make sure the activity radius 550mm.
After the installation of operator unit and sensor unit, calibration must be
taken. Please refer to the CALIBRATION page P8 for detail.
