RDO Optical Dissolved Oxygen Measurement

Note: Turn on the automatic datalog feature to send measurements to the meter
datalog at the frequency specified in each measurement mode. Refer to the Data
Archiving and Retrieval section for details. If the automatic datalog feature is off,
connect the meter to a printer or computer to record the measurements.
1 . Rinse the RDO sensor with distilled or deionized water . Shake off any excess
water and blot the sensor dry with lint-free tissue .
2 . Place the RDO sensor into the sample .
a . If the meter is in the continuous measurement mode, it will start reading
immediately and continuously update the display . The mg/L or % sat icon
will flash until the reading is stable . Once the reading is stable, log and print
the measurement by pressing
meter battery power .
b . If the meter is in the AUTO-READ measurement mode, press
the reading . The AR icon will flash until the reading is stable . Once the
reading is stable, the meter will log and print the measurement and freeze
the display . This mode uses various amounts of meter battery power,
depending on how often
c . If the meter is in the timed measurement mode, it will take a dissolved
oxygen reading at the frequency specified in the setup menu . If parameters
other than dissolved oxygen are measured, the meter will continuously take
the other readings and update the display . The meter will log and print the
measurement at the predetermined time interval . This mode can be used
to extend the meter battery life, since the power consumption of the RDO
sensor is reduced, depending on the set time interval .
3 . Remove the RDO sensor from the sample, rinse it with distilled or deionized
water, blot it dry, place it in the next sample and repeat step 2 .
4 . Once all of the samples have been measured, rinse the RDO sensor with
distilled or deionized water and blot it dry . Consult the RDO sensor user guide
for proper storage techniques .
