Calibrate a Pressure-to-Voltage Transmitter
To calibrate a pressure-to-voltage transmitter (P/V):
1. Connect the Product pump to the transmitter.
2. Apply pressure from the pump.
3. Connect the 24 V to the transmitter.
4. Measure the voltage output of the transmitter.
5. Make sure that the read value is correct. If it is not correct, the transmitter must be
adjusted. See Figure 27 for connections.
