2-20 Close/Open Switching Module Channels Model 2700 Multimeter/Switch System User’s Manual
Remote programming — Multiple channel control commands
The commands to close and open the system channel are listed in Table 2-2.
Reference:
a. ROUTe:MULTiple:CLOSe <clist>
This command functions like the front panel CLOSE key (MULTI menu option) to
close channels. When you send this command to close the channels specified in the
<clist>, only those listed channels will close. Channels not specified are not
affected, and channel pairing is disabled.
NOTES Channels closed by ROUT:MULT:CLOS are not displayed.
The ROUT:MULT:CLOS command cannot be used to perform
thermocouple temperature measurements using the internal or
external reference junction. The simulated reference junction will
instead be used and the integrity of the temperature reading will be
questionable (“ERR” annunciator on). See
“Temperature
measurements,” page 3-33, for details.
NOTE For RS-232 operation (and in some cases, GPIB operation), *OPC
or *OPC? should be used with :ROUT:MULT:CLOS if the <clist> is
large. Details on *OPC and *OPC? are provided in
Section 12.
