Dissolved Oxygen Calibration
Perform daily calibration for best results. Dissolved oxygen levels vary
with temperature, barometric pressure, and salinity, so calibration must be
performed with consideration of these factors. It is necessary to adjust the
barometric pressure and salinity values and calibrate the temperature prior
to performing any DO calibration or measurement. For probe operation,
refer to RDO Operation Instructions.
The 450 series can accept one or two calibration values; typically 100
% using saturated air or air-saturated water, and 0 % using zero oxygen
solution. If calibrating for 0 % oxygen, note that the meter will take several
minutes to reach 0 % saturation value and constant stirring is not required.
100 % Saturation Automatic Calibration
1. Rinse the probe well with clean water. From % saturation mode, press
CAL.
2. The primary display will show the calibration value, while the secondary
display shows the unadjusted value and the lower display shows the
measured temperature.
3. Place the probe in the optional calibration chamber or a saturated
oxygen environment (air or air saturated water) & wait for the reading to
stabilize. Press ENTER to accept.
0 % Saturation Automatic Calibration
1. Rinse the probe well with clean water. From % saturation mode, press
CAL.
2. The primary display will show the calibration value, while the secondary
display shows the unadjusted value and the lower display shows the
measured temperature.
3. Submerse probe in zero oxygen calibration solution and stir. Wait for the
reading to stabilize – this can often take more than 10 minutes. Wait for
the reading to stabilize. Press ENTER to accept.
mg/L or ppm Manual Calibration
1. Rinse the probe well with clean water. From mg/L or ppm mode, press
CAL.
2. The primary display will show the calibration value, while the secondary
display shows the unadjusted value and the lower display shows the
measured temperature.
3. Place the probe into a sample of known oxygen concentration (i.e.
determined by titration or another instrument). Wait for the reading to
stabilize. Press t/s to adjust the value and ENTER to accept.
Temperature Calibration/Manual ATC
1. Press CAL from any measurement, then press MODE.
2. Skip to step 3 for manual ATC, otherwise, dip the temperature sensor
into a solution with a known accurate temperature. The upper display
shows the active temperature while the lower display shows the factory
default temperature without adjustment.
3. Use up/down arrows to adjust the upper display. Press ENTER to accept
the calibration temperature. The maximum adjustable value is ±10 ºC
(or ±18 ºF) from factory default.

Error Messages
"ERR" will appear when an error condition exists or the incorrect
key is pressed. Common examples include:
• Pressing ENTER during calibration before the "READY" indicator appears.
Wait for the "READY" indicator before pressing ENTER.
• UR (Under Range) • OR (Over Range)
Intended Use, Maintenance & Precautions
These handheld meters use sensors to detect various parameters for water-
based measurements. For routine maintenance disconnect the power cord
or battery, then dust or wipe the display using a damp cloth. If necessary,
warm water or a mild water based detergent can be used. Immediately
remove any spilled substance from contact with the meter using the proper
cleaning procedure for the type of spill.
• Do not use this equipment in potentially explosive atmospheres.
• Refer to the electrode instructions for use, storage and cleaning.
• Ensure that no liquid enters the instrument.
• Do not use any aggressive cleaning chemicals (solvents or similar
agents).
• There are no user serviceable parts inside. Attempts to service internal
parts may void the warranty.
• Not intended for medical applications or patient use.
• WARNING: No modifi cation of this equipment is allowed.
