DCI Selects DC current measurement function.
ACI Selects AC current measurement function.
Ω2 Selects 2-wire resistance measurement function.
Ω4 Selects 4-wire resistance measurement function.
FREQ Selects frequency measurement function.
TEMP Selects temperature measurement function.
Shifted
MATH Configures and controls mX+b, percent, or reciprocal (1/X) calculation.
OUTPUT Configures and controls digital and audio (beeper) output for limits.
RATIO Enables/disables channel ratio.
CH-AVG Enables/disables channel average.
CONT Configures and controls continuity test.
OCOMP Enables/disables offset compensated ohms with Ω4 function selected.
PERIOD Selects period measurement function.
SENSOR Configures temperature measurements.
Middle Row
Unshifted
EXTRIG Selects external triggering (front panel, bus, trigger link) as the trigger source.
TRIG Triggers a measurement when in external triggering (EX TRIG).
STORE Sets the number of readings to store and enables the buffer.
RECALL Displays stored readings and buffer statistics. Use the , , Δ, and ∇ keys to nav-
igate through buffer.
FILTER Enables/disables filter for selected function.
REL Enables/disables relative for selected function.
 and  Dual function—Manually scans switching channels. When in a menu, these keys
control cursor position for making selections or change values.
Shifted
DELAY Sets user delay between trigger and measurement.
HOLD Holds reading when the selected number of samples is within the selected tolerance.
LIMITS Sets upper and lower limits for readings.
ON/OFF Enables/disables limits.
TYPE Configures and enables filter for selected function.
MONITOR Selects and enable/disables monitor channel.
CH-OFF Disables channel for a scan (must be in scan channel setup mode).
CARD Identifies switching modules installed in mainframe. Set up switching modules that
require configuration. View closed channels and channel settings for switching
modules that require configuration.
