* Orion Star A329 meters offer the option to use the measured conductivity value of a sample
for automatic salinity correction of dissolved oxygen measurements.
Details
Set the type of dissolved oxygen sensor connected to
the meter as DO polarographic or RDO optical or
select Auto and the meter will automatically detect
which type of dissolved oxygen sensor is connected
and update the displayed measurement mode
Set the units displayed with the dissolved oxygen
measurement value
1 Set the resolution of the dissolved oxygen
0.1 measurement value as percent saturation
0.1 Set the resolution of the dissolved oxygen
0.01 measurement value as mg/L
Set the read type to determine how the meter takes a
measurement and when the measurement is sent to
the data log and/or external device
00:00:03
Set the automatic barometric pressure compensation
source as the internal barometer (Auto) or a manually
760.0mmHg
entered barometric pressure value (Manual)
Enter the salinity value of samples for automatic
0.0 salinity correction of dissolved oxygen measurements
Set when a measurement is recognized as stable,
Smart Stability compensates for measurement
conditions and optimizes the meter response time
Set averaging for faster measurement stability,
Automatic Smart compensates for measurement
conditions and optimizes the meter response time
Set the limit alarm off or on, when the limit alarm is
on – select the alarm settings as high, high/low or low
On
and then enter the measurement limit values
High/Low Low
The limit alarm is triggered when a measurement
goes above the entered high limit or below the
entered low limit
Set the calibration due alarm off or on, when the cal
due alarm is on – enter the calibration time interval in
Off
hours (1 to 9998 hours)
The cal due alarm is triggered after the entered time
has elapsed without a calibration being performed
