Query SAMP:COUN? Retrieves the number of samples per trigger
presently set in the Meter.
SAMP:COUN? MIN Returns 1 to indicate the minimum number of
samples the Meter will accept per trigger.
SAMP:COUN? MAX Returns 50,000 to indicate the maximum number
of measurements the Meter will accept per
trigger.
TRIGger:COUNt <n>
Description Sets the number of triggers the Meter will take before switching to an idle
state. This setting is stored in volatile memory.
Parameters <n> = 0 to 50,000 Number of triggers before Meter becomes
idle.
MINimum Number of triggers is set to 1.
MAXimum Number of triggers is set to 50,000.
INFinite Continuously accepts triggers. A device clear
is required to set the Meter to idle state after
INFinite has been set.
Examples TRIG:COUN 430 Number of triggers set to 430.
Query TRIG:COUN? Retrieves the number of triggers presently set in
the Meter. Returns 9.90000000E+37 if trigger

Using System-Related Commands
FETCh[1/2]?
Description Moves measurements stored in the Meter’s internal memory to the output
buffer. FETCh1? or FETCh? returns measurements from the primary
display. FETCh2? Returns readings from the secondary display.
Example FETCh2? Retrieves a single measurement from the Meter’s
internal memory that was taken by the secondary
display if the secondary measurements are
enabled.
FETCh3?
Description Retrieves the last measurement from the Meter's primary display. Unlike
the FETCh? or FETCh1? commands which require that the meter be first
placed in the "wait for trigger" state using the INIT command to trigger a
measurement or multiple measurements from the primary display,
FETCh3? will return a single measurement from the primary display if
there is one. If a measurement isn't available, the command is ignored.
Examples FETCh3? Retrieves the last measurement from the primary
display of the Meter.
