Switch System User’s Manual
NOTE Installation of Keithley switching modules in the mainframe of the Model 2790
is covered in Section 4.
Details on using the Keithley 7702 module are provided in the Model 2790
Reference Manual.
Details on using the ohms functions of the Model 2790 with the 7702 module are

For remote programming, the <clist> parameter is used as follows:
<clist> = (@SCH)
where: S = Mainframe slot number (1 or 2)
CH = Switching module channel number of source (2 digits)
Examples: (@201) = Slot 2, Channel 1
(@201, 214, 218) = Slot 2, Channels 1, 14, and 18
(@201:210) = Slot 2, Channels 1 through 10
Safety precautions
In a system to test inflators, a 7702 module may be used with the 7751, 7752, or 7753
module. In a mixed-module configuration like this, the following safety precautions must
be understood and taken:
• External energy sources should never be applied directly to a 7751, 7752, or 7753
module for any reason. Damage to the module and any connected devices under test
can result due to the application of improperly selected or performing external
energy sources.
• Additional precautions should be taken when using the mainframe measurement
functions for the 7751/7752/7753 modules and an external source, connected
through the Model 7702 switch module. In the case of a single hardware or software
configuration error, or in a fault condition, external energy sources can become
directly connected to unintended device under test connections. Where this possibil-
ity exists, it is the system designer/builder’s sole responsibility to ensure, under all
such fault conditions, that no hazardous or damaging situations are created.
