3.3 Screen While Measuring
During a measurement the integrated amount of particles is displayed as
an indicated value, and the bar graph indicates the instantaneous value of
relative concentration (CPM: Count Per Minute). The measurement time
bar graph and the remaining time display indicate the remaining time of
the measurement. When the bar graph display disappears, the
measurement is finished.
This instrument’s measurable count number is 0 ~ 999,999. If the count
number exceeds this measurable range, “OVER” will be displayed on the
screen.
In MANUAL Mode the elapsed time is displayed.
In CALCULATION Mode, [the number of measurements performed /
total number of measurements] will be displayed where the selected
measurement mode is displayed in other modes.
