A
DJUSTMENT OF TEMPERATURE COMPENSATION
Only for sensors mic+.../TC, ,mic-...M from 2004 and pico+
For very precise measurements the temperature compensation can be adjusted. For that a sound-hard
reflector is positioned in the exactly measured distance to the sensor and sends this distance information
to the sensor.
 Install the sensor according to operating manual at his later field and you turn on the operating
voltage. Wait approx. 30 minutes until the sensor reached his final operating temperature.
 Position a flat plate (for example Epoxy-, Metal-, wooden board or smooth carton) with the least
measurements 100 x 100 mm in a normal way achieved to the sensor into the sonic field. Position
the plate for instance in the field of the detection range of the sensor, if this is not possible into the
maximally possible distance.
 Measure the distance as exactly as possible with a tape measure between sensor membrane and
plate. Enter the determined value into the input field >real distance<.
The following step is not to be cancelled. Assure that the steps 1...3 were carried out cor-rectly.
 Push the button >Execute<. The internal temperature compensation of the sensor is optimally
tuned by your real conditions of use. Pay attention, that the sensor due to his heat masses can
follow temperature changes not inertness-free.
