The following table describes the functions and shifted functions associated with each key. The
shifted functions are shown with a shaded background.
Key Function
DCV
Selects DC voltage measurement.
ACV
Selects AC voltage measurement.
Ω2
Selects 2-wire resistance measurement.
FREQ
Selects frequency measurement.
CONT
Selects the continuity test.
TEMP
Selects RTD temperature measurement.
ENTER
Accepts selection, moving to next choice or back to measurement display.
DCI
Selects DC current measurement.
ACI
Selects AC current measurement.
Ω4
Selects 4-wire resistance measurement.
Selects capacitance measurement.
Selects diode test.
TCOUPL
Selects thermocouple temperature measurement.
2ND
Sets secondary measurement.
TRIGGER
Sets the external trigger mode. When the TRIG indicator is lit, you can trigger the
instrument by pulsing the EXT TRIG input or by pushing the TRIGGER button to
generate manual triggers.
STORE
Stores a specified number of subsequent readings.
DIGITS
Changes display resolution. Note that changing the display resolution also changes
the integration time. If you change the digits to 4½, the integration time is set to
0.02 PLC. If digits are set to 5½, the integration time is set to 1 PLC.
NULL
Activates the null function in order to offset the measurement error due to the test
leads.
SHIFT
Used to access shifted-functions printed in blue over each key.
CONFIG
Configures the settings of selected measurement function. Refer to the topics in Basic
measurement functions (on page 3-1) for configuration details.
ESC
Cancels selection, moving back to measurement display.
AUTO/HOLD
Enables or disables the reading hold function.
RECALL
Displays stored readings.
FILTER
Enables or disables averaging digital filter.
MATH
Enables or disables mathematical operations/tests, including PERCENT, AVERAGE,
NULL, LIMITS, mX+b, dB, and dBm.
LOCAL
Switches the instrument to the local mode from the USB or GPIB remote mode.
MENU
Offers system-wide settings, trigger settings, and interface configurations. Refer to (7)
Menu overview (on page 2-10) for information about menus.
AUTO
Enables or disables autorange.
