In gasses other than air, the temperature variation may not correspond with the speed of
sound variation. In these cases turn off the temperature sensor and use a fixed
temperature.
P661 Temp Fixed
Use this feature if a temperature sensing device is not used.
Enter the temperature (in °C) of the atmosphere within the transducer acoustic beam. If
the temperature varies with distance from the transducer, enter the average temperature.
P663 Temperature Transducer Allocation
This feature may only be used for differential or average Operation (P001 = 4 or 5).
As preset, the temperature measurements of Ultrasonic / Temperature Transducer One
and Two are allocated to Points 1 and 2 respectively.
Use this feature if the temperature measurement from both transducers should be
identical, but one is located close to a radiant heat source. Allocate the temperature
measurement of the other transducer to both transducer Point Numbers.
Enter the number of the Transducer whose temperature measurement will be used for
the distance calculation of the Point Number displayed. When both transducers are
allocated to a Point Number, the temperature measurements from each are averaged.
