Assume the following channel attributes:
Channel
Backplane relays
Pole setting
DMM configuration
3001
none
2
'fourwireohms'
3002
3915
2
'fourwireohms'
3031
3921
2
N/A (paired channel)
3032
3921
2
N/A (paired channel)
NOTE The reason that 3031 and 3032 are paired channels (in this is example) is that the
channels 3001 and 3002 are configured with a DMM setting of "fourwireohms" (which
is a four-wire function). Two poles are supplied from the called channels, and two
poles from the channels associated by the "fourwireohms" configuration.
For this example, the following numbered operations are executed either from the front panel or
over the bus. Bulleted items that immediately follow the numbered operation indicate actions
that can occur with the operation:
1. channel open all
2. channel exclusive close 3001
 only 3001 closes (since no backplane relays have been associated with channel and channel
is not paired, in other words, not 4-pole)
3. channel exclusive close 3002
 open 3001 (no longer being requested as closed)
 close 3002 and 3915 (no channel pair since 2-pole and 3915 is backplane relay attribute
setting)
4. channel exclusive close 3031
 open 3002 and 3915
 close 3031 and 3921
5. channel exclusive close 3032
 open 3031
 keep 3921 close
 close 3032
6. dmm close 3001
 open 3032, 3921
 close 3001, 3031, 3911, 3922 (prepare for a 4-wire measurement, need paired channel and
corresponding backplane relays)
