Introduction
Introduction
The marine weather station AM706D is a multi-functonal
measuring instrument with wind speed, direction, temperature,
humidity and barometric pressure. It can accurately measure and
display real-time relative wind speed and direction, true wind speed
and direction, air temperature, relative humidity and barometric
pressure. In addition, it can regularly print these parameters and
time, longitude and latitude, ship speed, and navigational signal. It is
important and necessary for observation and safe navigation.
AM706D is approved by China Classification Society (CCS).
The main unit AM706D adopts three mounting methods, table,
hung and flush mounting. The wind sensor AM706S should be
installed on natural ventilated place, such as mast. Please note, big
Radar antenna rotation can disturb the wind measurement. The
AM706TH is suggested to be mounted on a place there is no direct
sunlight and rain drop.
Measurement Principle

2
Wind sensor sends relative wind direction and speed signal (relative
to ship bow and absolute value of angle signal) in digital interface
format of RS422 to main unit through junction box.
Temperature and humidity sensor provides air temperature and
humidity signal in digital interface format of RS485 to main unit
through junction box
Barometric pressure signal is received from internal IC sensor of
main unit.
Main unit uses these signals to calculate, display and export.
True speed and direction:
There are two ways to get the true direction and speed.
First way, connecting external GPS (RMC) data input, main unit can
calculate true wind direction (relative to North Pole) and speed.
Second way, connecting both Gyro(HDT) and Speed Log(VBW) data,
main unit can display the true wind direction and speed.

Power Failure Alarm
After turning on, it self-checks the both channels of power supply.
Anyone channel is disconnected, it will cause Power Failure alarm.
When power failure alarm is triggered, the main unit buzzer provides
long tone alarm (external alarm will not be on when power failure)
and red words ‘Power Failure’are flashing.
Alarm Mute
When alarm is triggered, press any button to mute the alarm
(Buzzer and external alarm), but flashing words are still on (External
light alarm is also on). When the alarm is triggered again, the system
