iSitu Calibration
About Calibration
Tap the Calibration icon in the iSitu App to access a list of methods by which to
calibrate the RDO sensor.
Note that the Salinity Setting in this list is not a calibration. It is a
manual setting only. See page 22.
Calibrate the Rugged Dissolved Oxygen Sensor
The RDO sensor requires very little maintenance. The zero oxygen calibration is
optional.
1. Tap the Calibration icon .
2. Select the method by which you intend to calibrate the sensor. This example
demonstrates a two-point calibration. Tap 100% and 0% Saturation.
33
3. Place a water-saturated sponge in the bottom of the calibration cup. Place the
instrument into the calibration cup, and tap Start.
The calibration cup must be vented to barometric pressure. Make
sure the vented cap is installed.
4. When the calibration is stable, tap the Accept button.
34
5. Remove the sponge and add fresh sodium sulfite solution to the fill line. Place the
instrument into the calibration cup, and tap Start.
Do not allow the sensor to touch the bottom of the cup.
6. When the calibration is stable, tap the Accept button.
35
7. To view the calibration report, tap View Report.
8. Rinse the sensors thoroughly with DI water.
36
Care and Maintenance
Maintenance Schedule
For best results, send the instrument to the manufacturer for factory calibration every 12
to 18 months.
User-Serviceable Parts
The user-serviceable parts on the instrument include the O-rings, and the RDO Sensor
Cap.
O-rings
The instrument has several O-rings that can be maintained by the user in order to keep
moisture from entering the instrument and damaging the electronics. Apply a very thin
layer of vacuum grease to new O-rings upon installation. The O-rings are located in the
following areas.
1 Connector (1)
2 Instrument housing (1)
3 RDO Sensor Cap (2)
RDO Fast Sensor Cap Replacement
The RDO Fast Sensor Cap has a 1-year typical life (15 months of total usage) after the
sensor takes its first reading, or 36 months from the date of manufacture. Follow the
instructions included in the RDO Sensor Cap Replacement Kit. Replacement caps are
available from In-Situ Inc. or your authorized In-Situ distributor.
Cleaning the RDO Sensor
Clean the Sensor Cap
1. Leave the cap on the sensor.
2. Rinse the sensor with clean water from a squirt bottle or spray bottle.
3. Gently wipe with a soft cloth or brush if biofouling is present.
37
4. If extensive fouling or mineral build-up is present, soak the RDO Cap end (while the
cap is still installed on the sensor) in commercially available household vinegar for
15 minutes, then soak in deionized water for 15 minutes.
5. Do not use organic solvents because they will damage the sensing material. Do not
remove the cap from the sensor prior to wiping.
6. After cleaning the sensor cap, perform a 2-point calibration.
Clean the Optical Window
1. Perform this task only once per year when you replace the sensor cap.
2. Pull to remove the sensor cap.
3. Gently wipe the optical window with the supplied lens wipe.
Important: Do not wet the interior lens area with water or any
solution.
