Using the DO/RDO Channel
Use the Orion Star A223 RDO/DO meter to measure dissolved oxygen as percent saturation or
mg/L and temperature using either Orion RDO optical or polarographic dissolved oxygen
sensors. The following chapter provides instructions on connecting sensors, calibrating the
system and measuring these parameters.
Meter and Sensor Preparation
1. Familiarize yourself with general meter operation and prepare the meter and accessories
according to the instructions in
Chapter 2 Meter Basics .
2. Refer to the instructions in Chapter 3 Meter Setup Menus to customize measurement and
calibration settings within the DO/RDO Channel setup menu and data transfer, data log,
date and time, language, sounds, display contrast and auto-shutoff settings within the
Instrument Settings setup menu.
3. Connect all necessary electrodes, probes and sensors to the appropriate meter inputs.
a.
Connect an RDO optical or polarographic dissolved oxygen sensor to the 9 pin MiniDIN
meter input. The meter will automatically detect which dissolved oxygen sensor is
connected. The temperature will also be measured when the dissolved oxygen sensor
is connected with the meter.
4. Prepare all connected sensors for use as instructed in the sensor manuals.
