rule, and the Break_Before_Make connection sequence.
13 to 15 Sets the bias port and the bias enabled output ports. And turns the bias mode ON.
16 to 17 Opens a message box to confirm the start of measurement. And clicking OK on the
message box displays a message on the console window.
Insert bias source control program code at the line 17.
18 Turns the bias mode OFF.
19 to 28 Same as the code shown in the lines 13 to 22 of Table 4-3.
