Line Description
47 to 48 Sets the high speed ADC, and selects it for all measurement
channels.
49 Resets time stamp.
50 Calls the check_err subprogram (shown in Table 3-1) to check if
an error status is returned for the previous line.
52 Applies voltage to device.
54 to 59 Declares a variable, and defines the value. This variable is used
for the step value of the secondary sweep source.
61 to 62 Declares a variable, and defines the value. This variable is used
for the output value of the secondary sweep source.
64 Sets the array counter i to 0.
