Un-shifted
DCV1
Selects Channel 1 voltage measurement function.
DCV2 Selects Channel 2 voltage measurement function.
V1/V2 Selects Ratio (Channel 1 voltage reading / Channel 2 voltage reading).
ACAL Selects automatic gain calibration.
FILT Enables/disables filter for selected measurement function.
REL Enables/disables relative for selected measurement function.
TEMP1 Selects Channel 1 temperature measurement function.
TEMP2 Selects Channel 2 temperature measurement function.
Shifted
MX+B
Multiplies a scale factor (M) to the reading (X) and then adds an offset (B).
% Calculates percent deviation from a specified reference.
V1-V2 Selects Delta; (V1t1 – V1t2)/2.
LSYNC Enables/disables line cycle synchronization. When enabled, noise induced
by the power line is reduced at the expense of speed.
TYPE Select filter (analog and/or digital) and configure digital filter (window,
count and type).
OUTPUT Enables/disables relative for Analog Output.
A
OUT
Enables/disables Analog Output.
TCOUPL Configure temperature measurement (units, junction type, thermocouple
type, sensor type).
Un-shifted
EX-TRIG
Selects external triggering (front panel, bus or trigger link) as trigger
source.
TRIG Triggers a measurement from the front panel.
STORE Sets reading count for buffer and enables buffer.
RECALL Displays stored readings (including maximum, minimum, peak-to-peak,
average, and standard deviation). The
and range keys scroll through
the buffer, and the and key toggles between reading number and
reading.
VALUE Set the upper and lower limits for limit testing.
ON/OFF Enables/disables limit testing, and selects beeper mode for limit testing.
and Controls cursor position for making selections or editing values.
Shifted
DELAY
Sets user delay between trigger and measurement.
HOLD Holds reading when the specified number of samples is within the selected
tolerance.
