Span faults can also be caused by a bad sensor, sensor at end-of-life,
or a sensor that is too far out of calibration for the Standard Zero/ Span
procedure to make the adjustment. An attempt to Initial Cal the sensor
may be able to correct the calibration; otherwise, the sensor must be
replaced. Additional sensor status can be obtained by right-clicking on
status group 3 to expand it as shown in FIGURE D-18.
