Line Description
30 to 41 Resets time stamp and performs the high-speed spot measurement. And stores the
returned data into the
mret and tret string variables. Finally, stores the measured data
into the data array.
43 to 45 Applies 0 V from the all channels. And transfers the data stored in the data variable to
the save_data subprogram (see Table 3-1 ). And the subprogram will save the data into a
CSV file specified by the fname variable and displays the data on a message box.
48 to 49 Displays a message box to show an error message if the error is detected.
