2-30 Close/Open Switching Module Channels
ROUTe:CLOSe?
ROUTe:MULTiple:CLOSe?
ROUTe:MULTiple:CLOSe:STATe? <clist>
These query commands are used to determine closed switching module channels.
ROUT:CLOS? is used to return a list of closed measurement channels including the paired
channel for 4-wire measurements. It will not return non-measurement channels. For
details, see
ROUT:MULT:CLOS? is used to return all closed channels (measurement and
non-measurement). For details, see
ROUT:MULT:CLOS:STAT? is used to return the state (open or closed) of each specified
channel. A "0" is returned for an open channel, and a "1" is returned for a closed channel.

Return the serial number and firmware revision.
Determine the maximum allowable voltage.
Determine if the module supports multiplexer or isolated channels.
Determine if the module has built-in temperature sensors for internal cold junction,
thermocouple temperature measurements.
Determine which channels are used for volts/2-wire measurements and which are
used for amps.
Determine which channels are used for analog or digital output.
Determine the totalizer channel (Model 7706 only).
