Sensor Zero Selection Menu

Select Sensor Calibration from the "Sensor Trim" Menu
Sensor calibration or "trim" functions are available from several
locations in the menu structure. See FIGURE D-8 for a view of this
selection menu.
First warning screen
Once the sensor calibration feature is selected, a warning message
displays to indicate that the 4-20 mA output should be disabled from
