Line Description
8 Defines the channel list in the channels variable (string).
9 to 12 Resets the Agilent B2200. And sets the Auto configuration mode, the Single connection
rule, and the Break_Before_Make connection sequence.
13 to 16 Sets the ground port and the ground enabled input/output ports. And turns the ground mode
ON. Open the ground enabled input ports to prevent the instruments from damage.
17 Closes switches to connect the input-output paths specified by channels.
17 to 27 Almost same as the code shown in the lines 13 to 22 of Table 4-3. The command used to
turn the ground mode OFF has been inserted to the line 21.
