Any integer number more than 1(one).

Specify the clock in nano sec.

If the value outside the settable range is specified, an error will occur during measurement.

NG Addition Clock

Any integer number more than 1(one).

Specify the value to be added to the starting clock when an error occurs.

Buffer Size

Any integer number more than 1(one).

Please specify it in units of [Scan Times].

Event Occurrence Interval

Any integer number more than 1(one).

Please specify it in units of [Transfer Times].

Measurement Information
