Operation and maintenance
To calculate the low trim (LT) value:
To calculate the high trim (HT) value:
Complete a 2051 Wireless sensor trim and enter the corrected values for low trim (LT) and high
trim (HT), refer to “Sensor Trim” on page 68.
Enter the corrected input values for low trim and high trim through the Field Communicator
keypad after you apply the nominal value of pressure as the transmitter input.
Note
After sensor trimming 2051 Wireless Range 4 and 5 transmitters for high differential pressure
applications, verify that the Lower and Upper Operating points are at nominal values using the
Field Communicator.
LT = 500 + (0.01/1000)(500)(1200)
LT = 506 inH

O (1.26 bar)
HT = 1500 + (0.01/1000)(1500)(1200)
HT = 1518 inH
