Frequently Answers and Questions

How does the SHM 30 sensor measure snow depth?
The SHM 30 snow depth sensor emits modulated visible laser light and determines the distance to an object by comparing phase information. To calculate snow depths automatically, the user can first perform a zero level measurement, which is stored as an offset value in the instrument.
How do I configure the SHM 30 sensor?
To configure the instrument, connect the serial interface RS232 or RS422. Any terminal program can be used to set and query data. Standard terminal programs are for example Hyper Terminal or Bray's Terminal. Standard configuration for the COM Port: 9600 Baud, 8N1, Handshake none.
What is the meaning of the different error codes?
Error codes are displayed in the data telegram and indicate a specific problem during measurement. Refer to the table in the manual for details on each error code and its meaning.
