transmitted. PV value is transmitted as first measured value, SV as seconed measured value.
Information:
The max. value for the PV to be transmitted is 999.99 inches (cor-
responds to approx. 25.4 m).
If the temperature should be transmitted in the Levelmaster protocol, then TV must be set in the
sensor to temperature.
PV, SV and TV can be adjusted via the sensor DTM.
