Function

AC current

AC plus DC rms current. Available in the primary display only.

DC current

Clears measurement from secondary display if one shown

Continuity test. Available in the primary display only.

Diode test

Frequency

Meter returns the function selected for the primary display as command mnemonic.

EXAMPLE: If frequency is selected for the primary display, "FUNC1?" returns "FREQ".

Meter returns the function selected for the secondary display as command mnemonic. If the secondary display is not in use, an Execution Error is generated.

EXAMPLE: If frequency is selected for the secondary display, "FUNC2?" returns "FREQ".

Resistance

AC volts

AC plus DC rms volts. Available in the primary display only.

DC volts

*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.
