On HMP probe models, the values of all available output parameters are locked when the sensor is being warmed by the sensor purge or condensation prevention functions.

Output parameter is available on this model.

Output parameter is available on this model, but its value is unavailable when condensation prevention functions are warming the sensor. Writing temperature to Modbus register 0334hex from an external source makes the output value available during condensation prevention.

Output parameter is not available on this model.
