Bourdon Tube Controller Calibration: Zero and Span Adjustment
WARNING
Refer to the Maintenance WARNING on page 51.
Note
For routine zero and span calibration, refer to the appropriate procedures in Section 3, 4, or 5. Use the following maintenance zero
and span adjustment procedure only if difficulty is encountered with the routine procedure or if nonlinearity occurs.
Refer to figure 6‐19 for location of adjustments and figure 7‐1 for key number locations.
Provide a means of applying process pressure to the Bourdon tube and a regulated supply pressure adjusted to the
normal operating pressure (see table 1‐6). For 4195KA and KS controllers, connect the controller output to an
accurate gauge. For 4195KB and KC controllers, a gauge is not necessary and the controller output connection may be
plugged.
