Sensor length
Length of SMA‑flat-ribbon sensor.
Foot height
Mounting height at the lower end of a tilted sensor (see Figure 10). For horizontally mounted sensors Foot height and Head height are equal.
Head height
Mounting height at the upper end of a tilted sensor (see Figure 10). For horizontally mounted sensors Foot height and Head height are equal.
Min. Coverage
The minimum length the sensor has to be covered in snow to yield valid measurements.
C base LF
Sensor adjustment value.
C base HF
Sensor adjustment value.
Sensor zero adjust
Function to perform a zero adjustment of the sensor (see Section Calibration of SMA‑2-flat-ribbon-sensors for details).
Test sensor
Function to perform a test measurement of the selected SMA‑sensor.
