I. GENERAL INFORMATION

You have just acquired a piece of high precision equipment which has been created using the most modern technology. It has been designed to

stand up to intensive use. However, in order to maintain its appearance and its precision, we recommend that you treat it with care and pay

careful attention to these operating instructions.

The GENERAL® Mini Airflow is fitted with an impeller and with sensors which allow it to carry out measurements in the open air.

It will give you all the information essential for your open air activities such as hang-gliding, rambling, climbing or water sports. It will give you the

instant wind speed and the maximum wind speed (DAF3010, 3300, 4000), ambient temperature and wind chill temperature (3010, 3300, 4000),

an electronic compass (DAF3300, 4000) as well as altitude, pressure, and trends in the weather (DAF4000).

The GENERAL® Mini Airflow range has been designed to withstand short-term immersion in water at a depth of up to one metre.

IMPORTANT !

This instrument is designed as an aid to users who are in an open air environment, but IT CANNOT replace advice and warnings from the local

weather station. This means that you should regularly check and compare the measurements provided by your instrument with the information

put out by the weather station.

Open-air climatic conditions can sometimes change quite dramatically and this can happen very quickly indeed. Sunny weather can, for

example, change to thunderstorm conditions in the space of half an hour and sometimes less. You should therefore always follow basic safety

rules whenever you undertake open air activity.

GENERAL TOOLS® can in no way be held responsible for any consequences, direct or indirect, or for any prejudice, which might result from

the use of this instrument.

Technical specifications:

Size: 41 x 93 x 17 mm

Weight : 52 gr (DAF3010, 3300), 53 gr (DAF4000)

Operational temperatures : -30°C to +60°C

II. MAINTENANCE DAF3010, DAF3300, DAF4000

The design and manufacture of this instrument have been the subject of a great deal of care. In order to make best use of the proposed

functions you are advised to use the instrument in accordance with the following observations :

•Avoid at all costs items such as hair, thread, sand and other dust materials getting into the impeller, as they could cause defective

rotation of the impeller and therefore a loss of precision. If a hair or a piece of thread should manage to get into the impeller, extract it

gently using tweezers; in the case of dust or sand, you can run clean water over the impeller.

•Avoid exposing the instrument to extreme climatic conditions for over-long periods. While it uses components resistant to such

temperatures, we recommend that you do not expose your instrument to strong sources of heat, for example under the windscreen of

a vehicle.

•Avoid careless use or sharp impacts.

•DO NOT EXPOSE the instrument to powerful chemicals. Such products could damage it.

III. Switching on DAF3010, DAF3300, DAF4000

To switch on your GENERAL® Mini Airflow, all that you need to is press briefly on the button(represented by on the diagram below). The

instrument switches on and displays the software version and the instrument model (see fig. D0.0 on the diagram below), after which the

instrument moves into the mode for measuring the current wind speed or to the last mode displayed before the instrument was

switched off.

IV. Switching off DAF3010, DAF3300, DAF4000

Switching off automatically (Auto-off):

Your GENERAL

Mini Airflow goes off automatically 1 minute after the button was last pressed or after the wind was last measured. This means

that it does not stop while the impeller is still turning (more than 10 seconds).

Switching off manually :

In order to switch Mini Airflow off manually (valid in every mode), hold the button pressed down until it switches off, then release.

IMPORTANT ! Permanent operation possible :

Either at the time of the manual switching off by releasing the button during the flashing of the large digits, or at the time of automatic switching

off by pressing briefly on the button during the flashing.

During permanent operation, any pressure on the button returns Mini Airflow into automatic off mode.

Note : if the instrument is on permanently the battery discharges rapidly (400 to 500 hours according to the model).

VI. Battery DAF3010, DAF3300, DAF4000

Your GENERAL

Mini Airflow gets its power supply from a replaceable lithium battery 3V type CR2032. To change the battery:

IMPORTANT ! This operation must be carried out with care!

ANY DEFECTIVE MANIPULATION DURING THE REPLACEMENT OF THE BATTERY CAN CAUSE LASTING DAMAGE

TO YOUR INSTRUMENT. IN CASE OF DOUBT CONSULT A WATCH REPAIRER.

1. Unscrew the metal back (6 screws).

2. Unscrew the screw of the battery cover.

3. Gently remove the cover in order to extract the battery.

4. Put in the new battery observing the polarity (+ upwards), then screw back the battery cover. Make sure that the tiny tongue in the

centre of the top is raised so that it touches the metal back.

5. Before refitting the back make sure that the seal is clean and securely positioned in its slot.

6. Refit the back and the 6 screws.

Normal battery life :

DAF3010, DAF3300 :approximately 30,000 measurements of 1 minute (auto-off) and more than 20 years when off.

DAF4000 : without records : same as DAF3010, DAF3300.

with records : approximately 25,000 measurements of 1 minute (auto-off), but 7 years maximum when off.

1. Backlight DAF3010, DAF3300, DAF4000

To get the backlight to light up keep the button pressed for 1 second and as soon as the backlight lights up, release the button. The backlight

remains illuminated for 3 seconds. If within the 5 seconds which follow you re-illuminate the backlight, it stays lit up for 15 seconds. Beyond

these 5 seconds, it lights up again for 3 seconds.

Note : the backlight lights up in the same way in all modes.

IMPORTANT : intensive use of the backlight reduces the life of the battery / consumption approximately 100 x greater than without

backlight.

2. Modes and mode changing DAF3010, DAF3300, DAF4000

Brief pressure on the button allows you to move to the following mode.

MODES :

DAF3010 (3 modes) DAF3300 (4 modes) DAF4000 (9 modes)

3. Mode for measuring the instant wind speed with maximum DAF3010, DAF3300, DAF4000

Choice of unit of measurement :

By keeping the button pressed for approximately 4 seconds, the units start to go past. You can choose between the

following units : km/h (kilometres per hour), mph (miles per hour), knots, m/s (metres per second), and fps (feet per

second). When the unit of your choice appears, release the button and the unit of measurement is thereby selected.

Measurement of speed :

For the measurement to be as exact as possible it is necessary to align the instrument along the axis of the wind.

Precision: +/- 3 %

Measuring range: from 0 to 150 km/h (42 m/s, 81 knots, 93 mph, 136 fps)

Measuring cycle: 2 measurements per second

Display:

The display of the current speed is done on the large digits and the maximum speed reached on the small digits with the indication .

Resolution : to one decimal place up to 99.9, then in whole units.

Deletion of the maximum :

The maximum is retained even when the instrument is off. In order to reset it to zero keep the button pressed for at least 2 seconds, then

release it.

4. Mode for measuring the instant wind speed with ambient temperature DAF3010, DAF3300, DAF4000

Choice of unit of measurement :

By keeping the button pressed down for at least 2 seconds the 2 units start to go past. You have the possibility to

choose between : °C (degrees Celsius) and °F (degrees Fahrenheit) When the unit of your choice appears, release

the button and the unit of measurement is thereby selected.

Measuring ambient temperature :

Note : the temperature sensor is integrated with the metal back of the casing, and therefore it is the temperature of

the back of the casing which is displayed. This special feature makes it possible to measure very accurately the

temperature of fluids such as :

water (springs, streams, etc.) by immersing the instrument several centimetres;

surfaces (ground, metal parts, refrigerator interiors etc) by laying as closely as poss ble the back of the instrument on the surface to be

measured;

ambient air, either by allowing the instrument to reach the air temperature, which can take several minutes, or even several dozens of

minutes according to the wind speed (avoid direct sun rays and contact of the back of the casing with your fingers). Otherwise, to get a

rapid and precise measurement, but the back of the casing into contact with an object which is the same temperature as the air (vehicle

bodywork, metal barrier, smooth walls etc.) avoiding surfaces in dark colours and exposed to sunlight).

Measuring range of the sensor : from -50°C to100°C

Measuring cycle: one measurement every 0.5 seconds

Display:

The display of the instant wind speed is done on the large digits while the ambient temperature is displayed on the small digits.

Resolution (temperature) : to the tenth of a degree

5. Mode for measuring the current wind speed with the wind chill temperature DAF3010, DAF3300, DAF4000

Low temperatures present a danger to the human body and this danger is aggravated by the speed of the wind. The

Mini Airflow meters show immediately the temperature felt by the body and warnsof risks of frostbite and

hypothermia.

WHICH MEANS : The wind chill factor is calculated on the basis of ambient temperature and wind speed. In the event

of wind, it gives an indication of the loss of heat by the body if the temperature is less than 10°C. This is the formula

which was adopted in January 2003 by the United States Federal Office for Meteorological Coordination with the

Meteorological Service of Canada (MSC), the US Department of Defence (DoD) and the United States National

Oceanic and Atmospheric Administration (NOAA).

Example: an ambient temperature of 0°C and a wind of 30 km/h act on your body as if the temperature were -7.8°C !

Choice of the unit of measurement for temperature :

See section 4, choice of the unit of measurement.

Display:

The display of the instant wind speed is made on the large digits and the wind chill temperature on the small digits with the indication .

Resolution (temperature) : to the tenth of a degree

Measuring cycle: 2 measurements per second
