Parameter
:CLOSe:STATe?
:ROUTe:MULTiple:CLOSe:STATe?
Description
The following commands let you close one or more channels at the same
time. They also let you manually select the 2-pole or 4-pole mode of
operation.
<list> = (@ chanlist)
where chanlist is the list of channels (1 through 11) to be closed.
This command lets you have multiple channels closed at the same time.
When this command is sent, the channels specified in the chanlist will close.
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.
This query command is used to determine which channels on the internal
scanner card are closed. After sending this command and addressing the
instrument to talk, a list of all closed channels is sent to the computer.
