Using the DO/RDO Channel
Use the Orion Star A213 RDO/DO meter or Orion Star A216 pH/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
a.
It is recommended that sensors be placed in the meter-attached electrode stand for
easy movement in and out of containers during calibration, measurement and storage.
2.
calibration and alarm settings within the DO/RDO Channel setup menu and data transfer,
data log, date and time, language, sounds, stirrer speed, display contrast, auto-shutoff, user
ID and sample ID 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.
b.
Connect the stirrer probe (Catalog Number 096019) to the Stirrer meter input.
4.
Prepare all connected sensors for use as instructed in the sensor manuals.
