* If AACDC or VACDC is selected in the primary display, no other function can be selected for the
secondary display. An execution error is generated if this is attempted.
Function Modifier Commands and Queries
The commands in Table 5-12 relate to the function modifiers. A function modifier causes
the meter to modify the normal operation of a measurement function (or perform an
action on a measurement) before displaying a reading. For example, the relative modifier
(REL) causes the meter to display the difference between a measured value and the rela-
tive base. The results of function modifier commands can only be shown in the primary
display. Refer to Chapter 3 for a more information about each function modifier.
