Suggested test tools Calibrating a HART smart pressure transmitter Pressure transmitter manufacturers have improved the accuracy and technology designed into these smart pressure measurement devices. Many conventional calibration tools have become inad- equate or simply unable to test and calibrate these high accuracy pressure transmitters. Better test solutions are required. Verifying and documenting the performance and adjusting a HART smart pressure transmitter can require a bucket full of tools. Performing this task with a HART enabled calibrator like the Fluke 754 simplifies the task and reduces what you need to carry. Before going to the field: install the pressure module adapter to the hand pump with thread seal. Once the adapter is properly installed on the pump, changing modules to different pressure ranges is a snap, no tools required. To get the accuracy needed: to test these new high accuracy transmitters match the pressure measurement standard range closely to the device tested. For example, use a 100 psi pressure module to calibrate and test a transmitter ranged at 100 psi. Industry standards suggest the measurement standard should be 4-10 times more accurate than the device being tested so best-in-class accuracy is required. The Fluke 754 utilizes the 750P series pressure modules and has built-in HART functionality to enable smart trims on trans- mitters. It can also document transmitter performance before and after adjustment and calculate pass/fail errors.
