Emerson 4500 manual Transmitter Data Flow with Calibration Options

Rosemount 4500

Figure 4-1also identifies the approximate transmitter location for each calibration task. Data flows from left to right, and a parameter change affects all values to the right of the changed parameter.

Not all calibration procedures should be performed for each 4500 transmitter. Some procedures are appropriate for bench calibration, but should not be performed during field calibration. Table 4-1identifies the recommended calibration procedures for bench or field calibration.
