Line Description
1 Beginning of the spot_meas subprogram.
3 to 12 Declares variables, and defines the value.
14 to 17 Applies voltage to device.
20 Performs the high speed spot measurement.
22 Sets the specified port to the zero output state.
18, 21, and 23 Calls the check_err subprogram (shown in Table 3-1) to check if an error status is
returned for the previous line.
25 Calls the display_data subprogram (next page) to display measurement data.
26 End of the spot_meas subprogram.
