Closing And Opening Channels - Keithley 7002-HD User Manual

Model 7002-HD User's Manual

Closing and opening channels

One of the basic operations of the Model 7002-HD is to close (or open) one or
more channels specified by the user. All the specified channels will either close or
open at the same time. An exception to this is when the Single Channel mode is
enabled. With Single Channel mode enabled, only the lowest numbered channel
in the lowest numbered slot will close.
NOTE
Perform the following steps to close and open channels:
Step 1. Select the channel list.
The channel list must be selected in order to close channels. The SCAN LIST key
toggles between the scan list and the channel list. If the channel list is not cur-
rently selected, press SCAN LIST. The following channel list prompt is displayed:
SELECT CHANNELS
Note that when the scan list is selected, pressing EXIT will also select the channel
list.
Step 2. Define channel list.
Enter channels into the channel list. The following example demonstrates proper
format:
SELECT CHANNELS 1!1, 4!1-4!10, M1,

4, and whatever channels are contained in the channel pattern stored at memory
location 1 (M1).
Step 4. Close (or open) listed channels.
Perform the appropriate close/open operation as follows:

Press the OPEN key to open channels that are listed in the channel list.
Note that only the listed channels will open. Any closed channels that are
