Values, Ranges
The digital measurement values are issued as unsigned digital values (raw values). 16 or 18 bits can be transferred per value. Below
you will find a compilation of the output values and the conversion of the digital value.

Bit 0 (LSB): peak starts before ROI
Bit coding
[0; 1]
Bit 1: peak ends after ROI
Bit 2: no peak found
SMR =Start of measuring range
Bit 5: Distance before SMR (extended)
EMR = End of measuring range
Bit 6: Distance after EMR (extended)
Bit 15: Measurement value is triggered
Bit 16, 17: Status LED;
- 00 – off
10 – red
- 01 – green
