Measurement of dmax Caused by Manual
Switching (Measurement mode: dmax)
Display during Measurement
Limit value
Observation period in measurement
An asterisk is displayed to the right of No.,
and dmax of that row displays the
maximum value within the observation
period. The values are updated when the
instantaneous values at every 2 seconds
exceeds the maximum values up to that
point.
Observation periods that have
completed measurements
For the dmax values in the observation
periods up to this point, “max” and “min”
are displayed to the right of the maximum
and minimum dmax values.
Number of the element whose measured data is displayed
Number and bar graph of the
observation periods that have
completed measurements
Elapsed time and bar graph within one
observation period
Flicker measurement status: Start
Edition number of the standard

Judge Display When the Measurement Is Complete
Flicker measurement status: Complete
Element judgment
For elements whose measured data is
displayed, the judgment result of the
average dmax value is displayed.
Total judgment
The judgment is Pass if the judgments of
all elements under measurement are
Pass; otherwise it is Fail.
Element under measurement
Judgment of the average dmax value
Of the 24 dmax values, the average of 22
data values, which excludes the maximum
(max) and minimum (min) values, is
displayed. The value is compared to its
limit value, and the judgment (Pass/Fail) is
displayed.
