36 to 37 Checks if an error occurred. If an error is detected, forces 0 V and goes to Check_err.
38 to 40 Applies voltage to device, and performs the linear search measurement.
42 to 46 Reads the returned data and stores it into the mret string variable. Finally, stores the
measured data into the data array.
48 to 50 Applies 0 V from all channels. And transfers the data stored in the data variable to the
save_data subprogram (see
CSV file specified by the fname variable and displays the data on a message box.
52 to 54 Displays a message box to show an error message if the error is detected.
