Advanced Configuration - Hach ORBISPHERE 410 Manuel D'utilisation Simplifié

Option Description
Type If enabled set the filter to Mean or Median.
Mean is the mathematical average of the last set (depth) of measurement
values.
Median allows for eliminating atypical peak measurement values and averaging
the remaining ones. The calculation sorts the last measurement set (depth) by
values, then ignores the highest and lowest values and averages the remaining
values (central depth).
Depth Number of measurements that make up a set.
Central Number of measurements to be used to determine the average.
depth
Example: With a depth of 7 and central depth of 5, the 7 values are sorted and the highest (7.0)
and lowest (0.9) eliminated. The average of the center 5 is calculated as 3.88:
0.9 1.1

7.3.6 Interferences configuration
These options are available to take into account the influence of some components or gases in the
sample during measurement. All available interference corrections are disabled by default.
The following interference corrections are available:
• For oxygen measurements - CO
4.0 4.3
Description
Check as appropriate.
This parameter defines the interval during which the outputs remain
frozen after the measurement is no longer on HOLD. Set the value to
between OFF and 10 minutes, according to the timing of your setup.
If thermal cutoff has been enabled (see
on page 17), then check this box to ensure that a continuous purge of
the TC sensor takes place while the measurement session is
suspended due to the thermal cutoff temperature value being
exceeded.
Note: To manually set the TC sensor into a continuous purge mode, press the
Continuous Purge button that is available from the Services - Diagnostic -
Channel x - Amplifiers menu.
Enable correction as appropriate. If enabled, the correction values for
offset and slope must be entered. These values cannot be negative.
Enable correction as appropriate. If checked, the percentage
correction factor must be entered. This value cannot be negative.
Note: If you believe you need to enable these corrections, it is advisable to
contact a Hach Lange Service Representative first.
