Silva ADC Wind User Manual

User Manual

1.0 General Guide

Thank you for purchasing your new ADC.
We recommend reading this manual, and
practicing the operations before using your
ADC in the field.

The ADC is designed to provide you with
information essential to your needs. Data
such as temperature, wind speed, barometric
pressure, altitude and humidity are features
specific to four different ADC models: Wind,
Summit, Pro and JetSet.

Each ADC model is constructed to withstand
water submersion and is ideal for conditions
you endure during outdoor activities such as
hiking, climbing, hunting, kayaking, skiing,
and racing. Every ADC also includes current
time, daily alarm, chronograph and race
timer functions. ADCs are equipped with a
propeller and other precise sensors to
measure outdoor conditions.

WARNING !

!

Make sure that you fully understand the
functions and limitations of the ADC
before relying on it.

!

The ADC is an assisting device for the
outdoor user, and is not a substitute for
weather advisories from a weather
station. It is helpful to check the
readings provided by this product
periodically with those broadcasted by
the weather station.

2.0

Prevent getting dirt in the ADC propeller. It
could clog the mechanism.

Avoid exposing this product to extreme heat
or extreme cold for an unreasonable amount
of time.

Avoid severe impacts to the ADC.

Store the ADC in a dry place when it is not in
use.

Clean the ADC with a soft moistened cloth
occasionally.

DO NOT expose the ADC to strong
chemicals such as gasoline and alcohol, as
they will damage this product.

Propeller Closed Propeller Opened

display

How Wind Speed is Measured

The ADC is equipped with a propeller that is

!

similar to a traditional aerovane.
When the propeller faces the wind, it

!

rotates and generates signal. This product
will pick up the signal and converts it into
wind speed.

Before and After Measuring a Wind Speed

Turn the ball-shape propeller by your thumb

!

and index finger until the propeller blades
are entirely exposed, and it is not sheltered
by the case.

! After a wind speed measurement, rotate the

propeller to a closed position to prevent dirt
from getting into it.

To Measure Wind Speed

Select Wind Speed Mode. Point the blades

!

directly towards the wind direction, and
make sure that the blades rotate freely.

When the wind passes through the propeller,

!

the blades rotate. The ADC starts to
measure, and shows the current, average
and maximum wind-speed readings.

Point the Propeller towards the wind direction

What is Beaufort Scale?

!

Beaufort Scale is the longest and most
widely used set of criteria to describe the
wind conditions and its effects on land as
well as on sea.

It categorizes the wind speed into 13 force

!

numbers, from 0 (calm) to 12 (hurricane).
Check the 'Beaufort Scale Table' section
below for more detail on the Beaufort Scale.

Beaufort Scale Bar

For user's convenience, the ADC displays

!

Beaufort Scale for average wind speed.
The ADC exhibits Beaufort Scale by

!

displaying different number of bars on the
upper row of the display. One exhibited bar
is equivalent to one Beaufort Scale force
number. For example, if there are 5 bars on
the display, the average wind speed is
equivalent to force number 5 of Beaufort
Scale.

The ADC displays the Beaufort Scale force

!

number from 0 to 10 (if the average wind
speed is higher than force number 10, the
ADC will display 10).

Wind chill is a temperature factor that
combines air temperature and the effect of
blowing wind.

!

As blowing wind makes you feel as though
the temperature is lower than simple air
temperature.

!

For example, if it is -9.4 degrees Celsius
and the wind blows at 80.5 km per hour:
People will feel as if the temperature is -23.3
degrees Celsius. In this case, the wind chill
temperature is -23.3 degrees Celsius.

The ADC is also equipped with wind chill

!

temperature functions, including displaying
current and minimum wind chill temperature,
and having a wind chill temperature alarm.

Note:

Wind chill temperature is the effect that

!

combines wind speed and temperature, the
ADC must measure the wind speed in order
to display the wind chill temperature.

Wind Chill Temperature Alarm Sound

!

In Temperature Mode: When the Current

Wind Chill Temperature is equal to or lower

the ADC starts beeping for about 5 seconds.

After the first beeping, the ADC will beep

1) When the temperature has been calibrated,
the ADC will offset the current temperature
by the target offset value. For example:
If the offset value is +2 and the current
temperature is 26 degrees C, the ADC will
display 28 degrees C (26+2).

2) The current wind chill temperature will be
