T EMPERATURE COMPENSATION
The velocity of sound in air is temperature dependent. The dependency can roughly be specified as 0,17
%/°C. To compensate this temperature influence, the temperature is internally measured and a correction
factor is calculated for the time-of-flight of echoes. The internal temperature compensation can be enabled
/ disabled by the check box Temp. Comp..
T OUCH C ONTROL
The ultrasonic sensors of the mic series are equipped with a control panel to manually adjust basic sensor
parameters via two push buttons (TouchControl). If the mic sensors should only be adjustable using the
Link-Control adapter, the control panel may be locked by unmarking the check box TouchControl. This is
helpful, if you want to prevent unauthorised, manual adjustment of sensors.
only for mic-.../M30: If on switching sensors the option window mode is activated, or on analogue
sensors the option end value delimiter, TouchControl is automatically reset, to prevent a subsequent
change of these complex settings via the control panel.
S ENSITIVITY
Only for sensors mic+.../TC or mic-...M from 2004!
C URRENT SAVING - MODE
Only for sensors mic+.../TC or mic-...M from 2004!
For the reduction of the current consumption, one can dim or switch off the display. For a further reduction
of the current consumption you can deactivate the synchronisation.
S YNC /M ULTIPLEX
Only for sensors mic+.../TC, mic-...M from 2004 and pico+
If the assembly distances for two or more sensors are exceeded, the integrated synchronisation should be
used. Within the multiplex operation every sensor can be assigned sensor an individual device address
between 1 and 10. The sensors perform the ultrasonic measurement sequentially from low to high
address. Therefore any influence between the sensors is rejected.
The device address >0< is for the synchronous working reserved and deactivates the multiplex mode. For
the synchronous working all sensors, the device address has to be >0<.
D ISPLAY MODE
Only for sensors mic+.../TC or mic-...M from 2004
On sensors with analogue output the display mode of the sensor-display can be changed.
