5.7.1 Sampling Interval (SI) and Integration Time (IT) Settings
5-17
Table 5-5 shows the setting range of the sampling interval.
Although the sampling interval (SI) can be set arbitrarily, use the minimum measurement time or more
shown in Table 5-6 as the sampling interval.
Although the sampling interval (SI) can be set to less than the minimum measurement time, the instrument
operates in the minimum measurement time.
Set the sampling interval according to the following procedure.
Enter the sampling interval in ‘SI’ in
