This section gives an overview of working with channels, including a discussion of channel types,
selecting channels, opening and closing channels, setting common channel attributes, and setting up
channel patterns.
To install the switching card, refer to instructions in the Series 3700A Quick Start Guide. For detailed
information about the Series 3700A switch cards, refer to the Series 3700A Switch and Control
Cards Reference Manual (Keithley part number 3700AS-909-01).
The switching channels of a Series 3700A have specific settings for switch-only operations and
specific settings for switch with DMM operations. The Series 3700A accesses different settings based
upon the close or open operation you specify. You can perform such operations on switching module
channels, analog backplane relays, and channel patterns.
Hot switching can dry weld reed relays such that they will always be on. Hot switching is
recommended only when external protection is provided.
