JETI model MVario EX Manual

MVario EX
The MVario System measures the atmospherical pressure and calculates with the obtained data the altitude
above sea level, the rate of climb as well as the rate of descent and records extreme values of these data. The
changes of rates of climb and descent are signalled and if preadjusted limits are exceeded, alerts are calling for
attention. Informations of the sensor are transmitted via the Duplex System to the user.
The Duplex System takes advantage of the 2,4GHz band for communication and is not only transmitting
model control data to the model, but is also receiving data from the model back to the transmitter. The telemetric
data gained during operation are shown as actual measured values in real time on the LCD screen of the
JETIBOX.
The sensor renders possible to adjust an acoustic signal for the climb rate/descent rate or for exceeding of a
preadjusted limit value. The acoustic signal consists of 4 different kinds (steps) for climbing and the same amount
of steps for descending. The step width can be adjusted by the user.
interrupted tones, the descent signal of long interrupted tones.
Design of the MVario Sensor:
The MVario is a sensitive barometric sensor. Any pressure change results in a change of altidude above sea
level, of climb rate a. s. o. The sensor should be solely influenced by static atmospheric pressure, not by any
airflow through the model. Therefore placement of the sensor in the model should be considered carefully. Place
the sensor in the model in a horizontal position (the MVario name sticker on top) in a position where only static
atmospheric pressure can have an effect.
MVARIO Sensor Menu:
Besides other competencies of the JETIBOX terminal it handles also duties like parameter adjustments and data
readout. After connection to the MVario sensor an introduction screen appears showing in the first line the
identification of the sensor and the realive altitude above sea level. In the second line you see the indicator and the
value of the Vario (climb rate/descent rate in m per 1s). The indicator of the Vario consists of eight positions. The
number of filled positions forms the size of the Vario indication. The symbol „>" stands for one step of climb. The
Symbol „<"stands for one step of descent. By long pushing down button R (right) a fast deletion of all measured
parameters can be triggered. Fast deletion is indicated in the first line of the display by an asterix „*".
By pushing the JETIBOX button D (downward arrow) you will enter the MVario sensor menu.
MVARIO MENU: ACTUAL VAL – by pushing the button D (downward arrow) you will select the display of actual
measurement values
Rel/Abs Altitude - relative and absolute altitude above sea level. After switching on a comparison basis (zero
altitude) is created from the absolute altitude for the relative altidude. The relative altitude is the result of the
difference of the actual absolute altitude and the comparison basis (zero altitude).
Vario – indicates the actual rate of climb/rate of descent in meters per 1s.
Abs. Pressure – indicates the actual atmospherical pressure in hPa.
Temperature – indicates the actual temperature of the sensor.
MVARIO MENU: MIN/MAX - by pushing the button D (downward arrow) you select recording of extreme values
which occured during measurements.
Vario MIN/MAX – indicates the minimum descent rate and the maximum climb rate
Altitude MAX – indicates the achieved maximum relative altitude
Temp MIN/MAX – indicates the minimum and maximum temperature of the sensor
MVARIO MENU: SETTING - by pushing the button D (downward arrow) you will change to the basic setup of the
MVario sensor.
Erase data – manual deletion of extremes. By simultaneous pushing of the arrow buttons R and L (right and left) all
records of measured parameters (minimum and maximum) will be deleted.
