2). pressure calibrator (std)
3). multi-meter (std)
4) hart communicator
1). ask panel man to put controller in manual mode for control loop and to put it MOS for ESD loop
2 ). hook up hart communicator and verify some parameters by refer to data sheet
Typical parameter are tag number, PV,LRV and URV
3). isolate the instrument from the process.
