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
Note: If you believe you need to enable any of the above, it is advisable to contact a Hach Lange Service
Representative first.
7.3.6.1 Interferences in oxygen measurement
In some applications, like in the beverage industry, there can be high concentrations of carbon
dioxide in the sample. Hach Lange recommends using the CO
dioxide concentration of over 1% in gas phase, or 15 ppm in dissolved phase is present.
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
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.
