device for transmitter?
 Question Submitted By :: Instrumentation
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Hart communicator is both a calibration as well as a
communicating device. As when we connect the two connector
to the transmitter it first communicate with the transmitter
ang gather all the data of the respective tansmitter and if
needed we can recalibrate it to a new range using the same
hart communicator.
