1. 3 & 5 point calibration
When calibrating the field instruments or device under test only 3 process reading compared with master instrument for 5 point calibration you should do comparison for 5 process values with master instrument
2. If we use hart communicator to set the LRV & URV of a
smart transmitter, did we calibrate the transmitter? why?
This is not calibration of transmitter we can say this is configuring BASIC parameters to the TX.
3. Make a complet list if meterials needed to properly
connect a pressure gauge to a steam pipe using 1/2 inch
stainless steel tubing. The gauge connections is 1/2 inch
NPT-M and the steam pipe tap has a 1/2 inch female coupling,
compression fittings are use.
By using sypon and 1/2 " nipple you can mount the pressure gauge on steam line if the line is vertical you should have 45 deg angle to the process line to reduce the pressure drop across the instrument.
8.. what are the two most commonly use programming languages
used when we configure a PLC?
