Figure 4-1 also 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.

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 4-1 identifies the recommended
calibration procedures for bench or field calibration.
