Orion Star Series Meter
Dissolved Oxygen
DO % Saturation Resolution:
This selects the displayed resolution in
measurement mode. In addition the resolution selection is used by Thermo Orion’s
SMART STABILITY & SMART AVERAGING algorithms to optimize the accuracy,
precision, and response of the DO measurement.
DO (mg/L) Concentration Resolution:
This selects the displayed resolution in
measurement mode. In addition the resolution selection is used by Thermo Orion’s
SMART STABILITY & SMART AVERAGING algorithms to optimize the accuracy,
precision, and response of the DO measurement.
DO Barometric Pressure Compensation Selection:
This selects whether
to use the instruments internal barometer for pressure compensation or use a
manually set pressure. In general we recommend using the internal barometer, but
you may wish to use manual pressure compensation if you are measuring DO with
a submerged probe or in a pressurized vessel where the probe is exposed to higher
pressures then the meter.
DO Manual Pressure Setting:
This screen will only appear if Manual Barometric
Pressure compensation has been selected. This is where you enter the pressure to
use for pressure compensating the DO measurement. The pressure in entered in
mm of Hg (Mercury). See the following table to convert from other units
of pressure.

Example:
To convert 14.1 PSI to mm Hg, multiple 14.7 by 51.7149 to get
750.21 mm Hg.
DO Salinity Correction Selection:
This screen will only be shown on meters
that have conductivity as well as DO. The Automatic setting takes the conductivity
reading to calculate the salinity correction factor and automatically applies that to
the DO measurement. A conductivity probe must be used in addition to the DO
probe for automatic salinity correction. The manual setting allow the user to enter
a manual salinity correction factor. Select the Manual setting and set it to zero to
disable salinity correction.
