Sensor MUI EX
-1-
Assignment of the MUI sensor is measurement of voltage, current and consumed capacity of flight
batteries in the model. The wireless data transmission by the DUPLEX 2,4GHz system is monitored by
the JETIBOX terminal.
For communication purposes the Duplex system takes advantage of the 2,4 GHz band, which besides
sending remote control data to the model also receives data from the model back to the transmitter.
During flight obtained telemetric data are transmitted in real time and the actual values of the measured
data can be displayed on the JETIBOX LCD. Telemetric MUI sensors execute voltage and current
measurements in your model and transmit these informations with the aid of the DUPLEX system
(receivers and transmitter modules). Thanks to exact current measurements these sensors render it
possible to trace the spent capacity of the measured battery. The MUI unit is recording the spent current
flow time and its average as well as maximum value. Furthermore it offers exact voltage measurements
and recordings of voltage minimum and maximum values.
The task of parameter adjustment and measured data setup is performed by the well known alround talent
– the JETIBOX terminal.
MUI sensors allow setting of acoustical signals in order to announce violation of set parameters. Such
alarms may be set for measurements of maximum current and minimum voltage as well as for a
maximum of consumed battery capacity. The sound signal is generated by a siren integrated in the
transmitter module. For better differentiation are the particular alarms distinguished by Morse alphabetic
letters. The acoustical alarm generation in case of parameter violation is working even if the JETIBOX is
not connected. With the JETIBOX in place the LCD display shows which parameter has been violated. In
case of violation of several parameters the alerts alter consecutively as well as the indications on the LCD
display.

Menu of the telemetric MUI Sensor
Take advantage of the JETIBOX for parameter adjustment and data readout. After connection to the MUI
sensor the sensor identification is shown and in the second line the preadjusted actual measured data. By
long pushing down button R (right) a fast deletion of all measured parameters can be triggered (min. and
max. voltage, max. current, average current, runtime, capacity). Fast deletion is indicated in the first line
of the display by an asterix „*“.
By pushing the push button D (downward arrow) of the JETIBOX you will enter the MUI sensor menu.
MUI MENU:
Actual Value
–
by pushing
D (downward arrow) you will select the display of actual
measured values
Volt / Current –
displays actual measured voltage and the current passing through the sensor. By
simultaneously pushing arrows R and L (right and left) the zero value of the sensor current is calibrated.
To the actual measured current value the zero current display is added, i. e. the so called zero shift.
Capacity
– shows the actual consumed capacity
Run Time
– shows the total time of current passage through the sensor. Included is also the time when the
current has exceeded the adjusted current value
Start Trigger
