Keithley 2000 User Manual

Pole mode is not affected by the selected measurement function. Instead, it is
selected by controlling channel 11, which is the 2-pole/4-pole relay. Closing
channel 11 selects the 2-pole mode. When channel 11 is open, the 4-pole
mode is selected. Use the rout:multiple:open <list> command to open channel
11.
Examples of a list:
list = (@1,3,5) Channels 1, 3, and 5.
= (@1:5) Channels 1 through 5.
When this command is sent, the front panel channel number annunciators are
disabled. Use the following query command to determine which channels are
closed.

:ROUTe:MULTiple:CLOSe:STATe? Query closed channels
Description This query command is used to determine which channels on the internal
scanner card are closed. After sending this command and addressing the in-
strument to talk, a list of all closed channels is sent to the computer.
