Page 17: Calibration Of Qfe Pressure
Calibration of QFE pressure In aeronautics, the QFE pressure corresponds to the pressure on the landing runway (ground level), and is used as the basis for calculating the height above ground level. Air traffic control will give you this pressure value. Select the lower block and display the measuring mode in relation to the QFE height (it flashes), then keep pushing button down. -
Page 18: Calibration
here are two types of compass display: bargraph on the compass block (always visible) and digit al display on the lower block. Select the lower block with the button (it flashes), then display the compass using the button. HICH MEANS : The default setting of the compass is for the magnetic North, and not for true North. -
Page 19: Flight Level
Flight Level Display In aeronautics. The Flight Level corresponds to an altitude expressed in hundreds of feet above the isobaric surface 1013.25 hPa, which allows all aeroplanes in the world to fly alongside each other risk-free, irrespective of the pressure values governed by local meteorological conditions. Select the lower block using the button (it flashes), then display the Flight Level with the help of the... -
Page 20: Enabling A Special Mode
To display the special menu, press and hold simultaneously the buttons, flashes on the upper block. When stops flashing, release the buttons. The special menu features 10 screens (7 screens for special modes and 3 screens for the memories): Navigate (switch from one screen to another) in the special menu with the help of the button. -
Page 21: Date And Time
Date and Time Display upper block: day of the week large block : date middle block: month lower block: time and year + seconds on the bargraph Operation The year is displayed by pressing briefly the button, release the button, and the time is shown again. The seconds are marked on the compass bargraph. - Page 22 The tendency is displayed using 63 values. The first 3 values show the variations in relation to the current pressure, the next 46 values in relation to the last measured pressure on the hour, and the last 14 in relation to the last pressure read at noon. To view the tendency (only if the special mode is enabled, please refer to Section: ‘Enabling a Special Mode’): display the barometric tendency mode, select the middle block (it flashes), then by pressing briefly the...

Page 23: Chronometer
The pressure displayed is that of 2 days earlier, i.e. the pressure recorded at noon (12:00) on April 28 . The instrument compares the last pressure read at noon (here, the pressure measured at noon on April 30 , 1011.9) with the pressure recorded 2 days earlier and displays the difference. -
Page 24: Operation
Operation Pressing both the buttons briefly at the same time launches the chronometer (brief display of the message ). This can be done from any screen, and whether the instrument is turned on or off. Pressing briefly the button freezes the screen, which allows to read an intermediate time (the instrument keeps counting the time while the display is frozen). -

button to select the direction of the adjustment ( increment, decrement), then set the value in degree of the declination with the help of the button. Keep the button down to confirm your setting, release it, and then press it down again to exit the special menu. IMPORTANT ! When a declination has been stored, all the display modes of the compass will show true North and no longer the magnetic North. -
Page 27: Operation
Operation It is not possible to modify any data on the finesse screen. It is necessary for the impeller to rotate and there must be a drop in altitude for finesse to be displayed. To calculate finesse, the instrument takes the mean wind speed as the horizontal velocity and the data supplied by the variometer as the vertical velocity. -
Page 28: Operation
Operation This type of memory displays all the recordings carried out manually. To record manually (from any screen, whether instrument turned on or off), press simultaneously the buttons for a short time. The message indicates that the recording has indeed been made. -
Page 29: Measurements Based On Selected Rate
Measurements Based on Selected Rate Display is displayed if the memory is empty (no recordings). The default screen is used to display the memory content. In the example shown opposite, this screen is the standard screen with the basic measuring modes (wind speed, temperature, digital and analogue compass heading). -
Page 30: History
History Display is displayed if the memory is empty (no recordings). The default screen is used to display the memory content. In the example shown opposite, this screen is the standard screen with the basic measuring modes (wind speed, humidity, relative pressure and compass heading). The upper block displays which flashes when being accessed. -
Page 31: Storage
Storage The example shown opposite indicates that the instrument is in the storage state; the clock and sensors have stopped, and there is no automatic recording. This is the default state of the instrument when it comes off the production line, thus avoiding the depletion of the battery if the instrument is stored for a long period of time. -

While the instrument is on, press simultaneously on the 3 buttons and then release: the following indications will appear: (the instrument is in the automatic stop mode), 127 (the software version) and the segments that are lit up (1 segment = 0.025V, no segment: <2.3V, all the segments lit up: >3.1V). -
Page 37: Calibration Of The Pressure Sensor
Calibration of the Pressure Sensor This operation is reserved to those professionals who hold a highly accurate laboratory standard. The consequence of any wrong calibration will be to supply erroneous data on all the measurements relating to pressure. Calibration is carried out from the measuring mode for absolute pressure. Proceed in the same way as with the other calibrations. - Page 38 From a few seconds to several minutes Humidity depending on wind speed instantaneous Pressure Compass instantaneous Measuring range of sensors Wind speed 0 to 300 (peak) km/h -40°C to +85°C Temperature Humidity 0.1 to 100%rH 10 to 1,100hPa Pressure -1,000 to 21,535m Altitude Perpetual calendar until 2175...
