Transmitter
First Claim
1. A method for start-up of a transmitter, comprising the steps of:
- feeding a user-defined transfer function (F) to a first electronic unit via a communication interfacetransmitting the transfer function (F) via a data line from the first electronic unit to a second electronic unit, thereby controlling said second electronic unit; and
storing said transfer function (F) in a memory assigned to the second electronic unit, wherein;
said transmitter, comprises a sensor, which serves for registering a physical parameter (X) and transducing such into an electrical quantity;
a signal pre-processor connected to said sensor, which serves for converting the electrical quantity into a raw signal (R);
a signal processor connected to said signal pre-processor, which serves for converting the raw signal (R) into a measurement signal (M);
an output stage, which serves for issuing an output signal corresponding to the measurement signal (M); and
a monitoring unit connected to said signal pre-processor, to said signal processor, and to said output stage which in operation compares the output signal with an auxiliary signal (H) derived from the raw signal (R) and triggers a safety-directed adjustment of the output signal, when a difference between the output signal and the auxiliary signal (H) exceeds a predetermined limit, wherein the transmitter further comprises an electronic unit, which serves for processing the fed measurement signal (M) according to said transfer function (F).

4. A method for start-up of a transmitter, comprising the steps of:
-
selecting a user-defined transfer function (F) present in the transmitter and feeding the user-defined transfer function (F) to a first electronic unit transmitting the transfer function (F) via a data line from the first electronic unit to a second electronic unit, thereby controlling said second electronic unit; and storing said transfer function (F) in a memory assigned to the second electronic unit, wherein; said transmitter, comprises a sensor, which serves for registering a physical parameter (X) and transducing such into an electrical quantity; a signal pre-processor connected to said sensor, which serves for converting the electrical quantity into a raw signal (R); a signal processor connected to said signal pre-processor, which serves for converting the raw signal (R) into a measurement signal (M); an output stage, which serves for issuing an output signal corresponding to the measurement signal (M); and a monitoring unit connected to said signal pre-processor, to said signal processor, and to said output stage which in operation compares the output signal with an auxiliary signal (H) derived from the raw signal (R) and triggers a safety-directed adjustment of the output signal, when a difference between the output signal and the auxiliary signal (H) exceeds a predetermined limit, wherein the transmitter further comprises an electronic unit, which serves for processing the fed measurement signal (M) according to said transfer function (F). - View Dependent Claims (5, 6)
