Line Description
35 to 38 Applies voltage to device and performs pulsed spot measurement.
40 Stores the measured data into the data valiable.
42 to 43 Applies 0 V from the all channels. And transfers the data stored in the data variable to the
save_data subprogram (see Table 4-1). And the subprogram will save the data into the
C:\Agilent\data\data6.txt file (CSV) and displays the data on a message box.
45 to 46 Displays a message box to show an error message if the error is detected.
