3.11 Parameter Entry
Parameter entry is accomplished using a sixteen position rotary switch labeled FUNCTION and three
momentary pushbutton switches labeled ENTER, VALUE, and DIGIT. These switches are located on the
right side of the main circuit board and are accessible by partially removing unit from its mounting case.
The FUNCTION switch is used to select the parameter to be entered. Table 3-3 defines the switch
positions and a description of each parameter can be found in the following paragraphs.
