Function Description
“Select program number“ adjusts the desire measurement program
“Measurement Start“ starts the measurement
“Measurement Stop“ switches the measurement off
“Measurement request“ supplies the value of the last measurement
“Adjust nominal thickness“ adjusts the nominal thickness for selected program
“Select sensor no. / sequence“ adjusts the desired sensor number / sequence
“Adjust lower limit in %“ adjusts the relative value of the lower limit (threshold) “low“
“Adjust upper limit in %“ adjusts the relative value of the upper limit (threshold) “up“
