Line Description

36 to 37 Sets the high speed ADC, and selects it for all measurement channels.

38 Resets time stamp.

39 Applies voltage to device.

41 to 60 Applies dc current and pulsed sweep voltage, and performs pulsed sweep

measurement. After that, disables all ports and stops the program execution if the

number of returned data is not equal to the nop1 value.

62 Sets the specified port to the zero output state.

34, 45, 48, 57,

and 63

Calls the check_err subprogram (shown in Table 4-1) to check if an error status is

returned for the previous line.
