Safety
l Do not submerge the battery pack or the mobile display device in liquid.
l Ensure that the pH/ORP sensor is completely inserted into the port, so that no
liquid can enter the instrument. The storage plug is not intended to be used when
the instrument is deployed in water.
l Ensure that the RDO Sensor Cap is pressed firmly over the sensor lens and is
flush with the instrument before submerging in liquid.
l Replace the cable if insulation or connectors are damaged.
l Make sure the probe and sensor O-rings are clean and free of damage.

A depth reference applies an offset equal to the distance from the
pressure sensor to a desired location, such as the bottom of the
probe, so that the depth reading is reported from the desired
location, rather than from the location of the pressure sensor.

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, the pH/ORP sensor,
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
2 Instrument housing
3 pH sensor
4 RDO Sensor
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.
pH/ORP Sensor Replacement
To replace the pH/ORP sensor or to refill the reference junction, follow the instructions
in the pH/ORP Sensor Instruction Sheet that is included with the replacement sensor.
Instrument Storage
To store the probe for a week or less, place the probe in the calibration cup with a few
drops of clean water to maintain a moist storage environment.
67
To store the probe for more than a week, perform the following procedure.
1. Remove the pH/ORP sensor and place the orange pH port plug into the empty
pH/ORP port to prevent any humidity from entering the probe.
2. Locate the sensor storage bottle in which the pH sensor was originally shipped.
3. Open the bottle and remove the O-ring.
4. Moisten the sponge inside the bottle with either a pH storage solution or a pH 4
solution.
5. Slide the O-ring onto the sensor, and then slide the bottle cap over the sensor as
shown.
6. Place the sensor tip in the buffer and tighten the cap to prevent the glass bulb from
drying.
Cleaning the pH/ORP Sensor
Begin with the gentlest cleaning method and continue to the other methods only if
necessary. Do not directly touch or wipe the glass bulb.
To clean the pH sensor, gently rinse with cold water. If further cleaning is required,
consider the nature of the debris.
Remove Crystalline Deposits
l Clean the sensor with warm water and mild soap.
l Soak the sensor in 5% HCI solution for 10 to 30 minutes.
l If deposits persist, alternate soaking in 5% HCI and 5% NaOH solutions.
Remove Oily or Greasy Residue
l Clean the sensor with warm water and mild soap.
l Methanol or isopropyl alcohol may be used for short soaking periods, up to 1 hour.
l Do not soak the sensor in strong solvents, such as chlorinated solvents, ethers, or
ketones, including acetone.
68
Remove Protein-Like Material or Slimy Film
l Clean the sensor with warm water and mild soap.
l Soak the sensor in 0.1M HCI solution for 10 minutes and then rinse with
deionized water.
Note: After performing any of these cleaning methods, rinse the
sensor with water and then soak overnight in pH 4 buffer.
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.
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.
Note: Vinegar is safe for all of the sensors on the probe including
the RDO Sensor if the Sensor Cap is on.
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.
Cleaning the Conductivity Sensor
1. Before you begin, ensure that the RDO Cap and the pH/ORP sensor are in place.
Rinse the conductivity sensor under running water to remove loose material.
2. Follow Cleaning Procedure 1. If debris is still present, progress to the next cleaning
procedure. If the debris is removed, skip to the last step.
69
Cleaning Procedure 1
Avoid damaging the plastic material of the conductivity cell. Gently scrub the
conductivity cell with a soft swab and mild soap such as a dilute solution of dish
detergent. The probe is shipped with polyurethane foam swabs for this purpose. You
can also achieve good results using a gentle back-and-forth motion with a thin cotton
pipe cleaner. If debris is still present, continue to Cleaning Procedure 2. If the sensor is
clean, skip to the last step.
Cleaning Procedure 2
Avoid damaging the plastic material of the conductivity cell. Gently scrub the
conductivity cell with a foam swab and an aggressive soap such as Alconox cleaner. If
debris is still present, continue to Cleaning Procedure 3. If the sensor is clean, skip to
the last step.
Cleaning Procedure 3
Soak the sensor with dilute acetic acid (10:1 solution) or commercially available
household vinegar to pre-soften calcium deposits. Follow this with Cleaning Procedure
1 or Cleaning Procedure 2, depending on the degree of residual contamination. The
probe can soak for any length of time in household vinegar. If debris is still present,
continue to Cleaning Procedure 4. If the sensor is clean, skip to the last step.
Cleaning Procedure 4
Topically apply dilute phosphoric acid (< 27 %) or the consumer product LIME-A-WAY
with a soft swab to remove iron or calcium deposits that remain after using Process 3.
Do not allow the cleaner to be in contact with the sensor for more than 10 minutes.
Rinse well with clean water and continue to the last step.
Check the sensor calibration before redeployment. Recalibrate the sensor when
necessary.
