a) Calibration of a temperature transmitter with RTD input and 4-20 mA output.
Through the menus, the calibrator is configured for mA input and RTD output. TPS, which stands for
Transmitter Power Supply, is a 12 Vdc power supply (rated voltage, which may vary depending on the load) which
feeds power to transmitter.
In the example, the RTD connection is made by using three wires, and it is simulated by the calibrator. With
this kind of connection, there is no measurement error due to the resistance of wires provided that they have the
same length and gauge.
