Scanning With an External Instrument

Configure the list of channels for 4-wire external scanning without the internal DMM. When enabled, the instrument automatically pairs channel with channel 87 (34901A) or D (34902A) to provide the

source and sense connections. For example, make the xz			connections
to the HI and LO terminals on channel 2 and the z		connections to
the HI and LO terminals on channel 12. Specify the paired channel in
the lower bank (source) as the vt	channel.

Note that the ROUT:CLOSe, ROUT:CLOSe:EXCL, and ROUT:OPEN commands ignore the current ROUT:CHAN:FWIRe setting (if no channels are in the scan list).

The :FWIR? query returns a “0” (4-wire pairing disabled) or “1” (4-wire pairing enabled) for each channel in the scan list.

INSTrument	5
:DMM {OFFON}
:DMM?
Disable or enable the internal DMM. When you change the state of the
internal DMM, the instrument issues a Factory Reset (*RST command).
The :DMM? query returns the state of the internal DMM. Returns “0”
(disabled) or “1” (enabled).
INSTrument:DMM:INSTalled?
Query the instrument to determine if the internal DMM is installed.
Returns “0” (not installed) or “1” (installed).
