Keithley 2700 User Manual

Model 2700 Multimeter/Switch System User’s Manual Close/Open Switching Module Channels 2-9
Controlling the system channel
When a measurement channel is closed, a previous system channel (and, for a 4-wire
function, its paired channel) is first opened. The closed measurement channel becomes the
system channel. When a 4-wire function is selected, the paired channel for the system
channel also closes.
 and  keys
These front panel keys (Figure 2-3) can be used to select the next or previous
measurement channel as the system channel. If there are no measurement channels
available, one of the following messages will be briefly displayed when one of these keys
is pressed:
NO SCAN CARD — This message indicates that there are no switching modules (or
pseudocards) installed; both slots are empty.
NO MEAS CARD — This message indicates that none of the installed switching
modules (or pseudocards) have measurement channels. For example, the Model 7705
switching module does not have any measurement channels. Those channels cannot be
internally connected to the DMM.
NOTE The  and  keys can also be used to open all channels in the mainframe.
Simply increment or decrement the channel number until there is no channel
displayed.
