:TSOurce <list> Select trigger source to start the scan (IMM, or
HLIM1, HLIM2, LLIM1, and LLIM2).
IMM
:TSOurce? Query trigger source for scan.
:NVOLatile <b> Enable or disable nonvolatile memory for
scanning (autoscan).
(Note 2)
:NVOLatile? Query nonvolatile memory setting.
:LSELect <name> Enable (INTernal) or disable (NONE) scan. NONE
:LSELect? Query state of scan.
Notes:
1. Default value depends on which switching module is installed.
2. Not affected by *RST and SYSTem:PRESet. Front panel factory default is OFF.
3. Not affected by *RST and SYSTem:PRESet. Interval set to 15 minutes at the factory.
4. The ROUT:MULT:CLOS command cannot be used to measure thermocouple temperature using the internal or external refer-
ence junction. The simulated reference junction will instead be used. See “Temperature measurements,” page 3-25, for details.
