6.9 Calibration examples

6.9.1 Example 1 – Calibration of 2-wire pressure transmitters
Pascal ET generates power supply of DC 24 V to the transmitter. The 4 ... 20 mA output signal from the transmitter is sent to
be measured to an electrical input signals card IN A or IN B.
The pressure reference value to the transmitter is generated by the hand pump and by the fine volumetric regulator, both
present in the calibrator, and measured as REF by the calibrator itself.
The figure below shows how to connect the transmitter to the calibrator.
