MT125 & MT300 Sensor EX
- 2-
Sensors of the MT300 Module can be used for higher temperatures (engine cylinders, engine exhausts
etc.). The sensors are adapted to this purpose and comprise a loop of heat resistant conductor in the
middle. Before tightening moisten the silicon tube with alcohol or white spirit in order to improve its
sliding ability on the cables. Put the measuring object, for instance an engine cylinder, through the loop
and tighten the loop strongly by means of the silicon tube in order to obtain a tight contact between the
loop and the measuring object (for instance with cooling fins of an engine cylinder). After evaporation of
the alcohol the silicon tube will firmly hold the loop tight. In order not to damage the sensor the dia. of
the loop should not be smaller than 20 mm.
Parameter adjustment of MT-Modules
Parameter adjustment a data readout is accomplished by the JETIBOX terminal. After connection to the
MT-Sensor there appears an identification of the sensor and in the second line the actually measured
temperature data of both sensors. 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 button D (downward arrow) of the JETIBOX you will enter the MT-Module menu.
Menu of the MT-Module:
MT125 MENU:
ACTUAL VALUE
–
select presentation of actual measured data by pressing button D
(down arrow)
Actual Temp. A –
presents the actual temperature of sensor A
Actual Temp. B –
presents the actual temperature of sensor B
MT125 MENU
:
MIN / MAX
– push button D (down arrow) in order to select the recorded extreme
values which occured during measurements on both sensors.
Temp. A MIN / MAX
– represents the minimum and maximum temperature value which has been
recorded by sensor A during all measurements.
Temp. B MIN / MAX
– represents the minimum and maximum temperature value which has been
recorded by sensor B during all measurements.
Records of all extremes can be deleted in the menu
Setting - Erase Data.
If you don´t delete all data
records manually, the MT-Module will record the maximum and minimum sensor temperatures whether
it has been in the meantime disconnected of the voltage supply or not, i. e. the presented data can concern
preceding operations.
MT125 MENU:
Setting
– by pushing button D (down arrow) the basic MT-Module adjustment will be
selected.
Erase Data
– pushing buttons R and L (right and left arrows) simultaneously will delete all records of
measured parameters (minimum and maximum temperature values of sensors A and B).
Beep Temp. A
– adjustment of a Morsealphabet character which will announce violation of the set alert
temperature of sensor A by an acoustic signal of the DUPLEX Tx transmitter module.
Beep Temp. B
– adjustment of a Morsealphabet character which will announce violation of the set alert
temperature of sensor B by an acoustic signal of the DUPLEX Tx transmitter module.
MT125 MENU:
ALARMS
– by pushing button D (downward arrow) you will enter the adjustment
modes of particular alerts. If violation of a set parameter occurs the indication of the JETIBOX LC
display will show in the second line of the basic menu the original indication as well as the particular alert
indication alternately and the siren of the transmitter module will emit alert signals. The first tone is a
reference signal and the second tone is the corresponding Morse signal of the particular alert. There will
be no particular signal emitted if the alert is in OFF position.
Temp. High A
– signal adjustment for high temperatures, if the measured temperature exceeds the set
value alert of sensor A will be activated.
Temp. Low A
– signal adjustment for low temperatures, if the measured temperature is below the set value
alert of sensor A will be activated.
Temp. High B
– signal adjustment for high temperatures, if the measured temperature exceeds the set
value alert of sensor B will be activated.
