Advanced Configuration - Hach ORBISPHERE 51 Serie Manuel D'utilisation Simplifié

Option Description
Depth Number of measurements that make up a set.
Central depth Number of measurements to be used to determine the average.
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:

Description
Check as appropriate.
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
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.
