The pressure transmitter should only be calibrated if the individual knows what they are doing. The calibration of the pressure transmitter needs to be done on the line of pressure.

To calibrate differential pressure, you will need a calibration instrument such as a pressure gauge or calibrator. Connect the instrument to the differential pressure device, apply a known pressure, and compare the readings from the device to the instrument. Adjust the device's output if necessary to match the known pressure applied for accurate calibration.
Pressure gauges can be calibrated using a reference gauge or a calibration standard with known pressure values. The gauge is subjected to various pressure points, and the readings are compared to the reference standard. Adjustments are made as necessary to ensure that the gauge accurately reflects the applied pressure. Calibration can be performed manually or using automated calibration equipment for increased precision.
Pressure is usually measures and calibrated in "bars".
The calibration curve for an orifice meter will depend on the size of the orifice, the size of the pipe and the pressure loss over the meter. Typical calibration curves have pressure (or head) loss on the vertical (y) axis and flow rate on the horizontal (x) axis.
Calibration is the intercomarison and adjustment (if necessary) of a device with a "standard" of known higher accuracy. A quick test of temperature calibration are the freezing and boiling points of water (which varies somewhat based on altitude). Pressure is tougher and needs to be done by a calibration laboratory.

calibration is ocmpression between two part 1)electrical (AC,DC VOLTAGE ,CURRENT,RESISTANCE) 2)non electrical (PRESSURE,TEMPRATURE)
To calibrate compound gauges, you will need a calibration pump and a pressure calibrator. Connect the compound gauge to the calibration pump and apply pressure using the pressure calibrator. Compare the readings on the compound gauge with the readings on the pressure calibrator and make necessary adjustments to bring them into alignment.
