Model 2701 User’s Manual Close/Open Switching Module Channels 2-15
Making amps measurements — In order to perform amps measurements, you must use
the front panel inputs of the 2701 mainframe. You can still use the non-amps module for
other aspects of the test, but you must use multiple channel operation to close channels.
Example:
NOTE In order to use the front panel inputs, make sure the INPUT switch is in the out
(F) position.
SYST:PRES ' Restores system preset defaults.
ROUT:MULT:CLOS (@101) ' Closes channel 101.
SENS:FUNC ‘CURR:DC’ ' Selects DCI function – Legal operation.
Non-measure switching modules
NOTE Presently, non-measure Keithley modules include the Models 7705, 7711, and
7712. You can check the Keithley website (www.keithley.com) for new modules.
Keep the following in mind when using a non-measure module:
• For a non-measure card, no channels are connected to the internal DMM (the
channels cannot be connected to the backplane).
• Multiple channel operation should be used to close channels on a non-measure
module. For remote operation, the ROUT:MULT commands are used to close
channels.
• Front panel system (single) channel operation cannot be used to close channels on
a non-measure module. For front panel operation, system channel operation will
cause message “NO MEAS CARD” to be displayed.
• A non-measure module may have open/close operations that are specific only to
that module. Refer to the appropriate module manual (packing list) for details on
operation.
• In order to perform measurements, you must use the front panel inputs of the 2701
mainframe. You can still use the non-measure module to control other operations.
