Part number 0085490, Rental R79420
Overview
The S2XP restrictor is shipped in two pieces. The
restrictor must be installed in separate steps to allow for
sensor calibration.
It is recommended you follow all steps in this instruction
sheet to properly set up your TROLL 9500 S2XP
system.

pH, ORP, and Conductivity Calibration
1. Detach the Cal Cup from the TROLL 9500. The Cal
Cup contains a small amount of liquid to hydrate the
pH sensor during shipment. Discard this liquid.
2. Thoroughly rinse the sensors with clean water.
3. Fill the Cal Cup to the fill line with Quick Cal solution.
Reinstall the Cal Cup on the TROLL 9500. See
Figure 1.2. Do not over-tighten.

4. In Win-Situ 4, click on Parameters in the Navigation
tree.
5. Click Quick Cal. Select pH, ORP, and Conductivity.
6. Click Start. You must hold the TROLL 9500 vertically
for proper calibration.

Initial Installation
1. Remove the Cal Cup. Dispose of the Quick Cal
solution.
2. Thoroughly rinse the sensors with clean water.
3. Gently dry sensors with a paper towel.
4. Remove the pH/ORP sensor by inserting the removal
tool (located in the accessories kit) underneath the
sensor. See Figure 1.3. Note the sensor's port
location (port 1) for reinstallation.

7. Feed the RDO cable through the restrictor cap of
restrictor B. See Figure 1.6.
Figure 1.3 Removing the pH/ORP sensor
5. Remove the conductivity sensor using the removal
tool. See Figure 1.4. Note the sensor's port location
(port 4) for reinstallation.

8. Connect the RDO cable to the TROLL 9500 in port 3
(the center port). See Figure 1.7.

9. Reinstall the pH/ORP sensor to port 1 and the
conductivity sensor to port 4. A diagram on the
TROLL 9500 body designates port locations. Be sure
the sensors are fully inserted before proceeding.

10. Refresh Win-Situ 4 to ensure all sensors are correctly
attached to the TROLL 9500. pH, ORP, Conductivity,
and Rugged Dissolved Oxygen should appear under
Parameters in the Navigation tree.
11. Rotate restrictor B onto the TROLL 9500 body. Do not
fully attach the RDO sensor to the restrictor cap yet.
RDO Calibration
5. In Win-Situ 4, select Rugged Dissolved Oxygen in
the Parameters list.
6. Before the DO Calibration Wizard starts, you will be
asked how you want to handle barometric pressure. If
the TROLL 9500 will be deployed on a vented cable,
Instruction Sheet
click No. If it will be deployed on a non-vented cable,
click Yes.
7. Three calibration options appear. Select the first or
second option:
The RDO sensor should be calibrated prior to being fully
installed into the S2XP restrictor. Normally, a one-point
100% saturation calibration is sufficient.
A two-point (100% and 0% saturation) calibration is
recommended when very low DO values (<1 mg/L) are
expected, or after the sensor cap has been replaced.
Standard Operating Procedures may also require a
two-point calibration.
Oxygen Saturation Point (100%) Calibration
1. Remove the two batteries from inside the bubbler and
install them into the air pump, as shown on the
diagram on the inside of the air pump lid.
2. Fill the bubbler with clean water that is similar in
temperature to what is expected in the field.
3. Turn on the bubbler. Open the pinch valve on the
bubbler tubing and allow the bubbler to run for 10
minutes. For best results, run at the full flow rate to
achieve saturation; after 10 minutes you can use the
control valve to match the water turbulence conditions
expected in the field.
4. Lay the TROLL 9500 on its side and insert the RDO
sensor into the bubbler. See Figure 1.8. Ensure that
the sensing element is not in the direct path of the
bubbles.
l Calibrate: Starting from values stored in the sensor
(user-set or factory defaults) for the 0% and 100%
calibration, this allows the user to redo one or both
calibration points.
l Restore defaults, then calibrate: Restores factory
defaults for both 0% and 100%, then allows the user to
redo one or both calibration points.
l Restore defaults, don't calibrate: Restores factory
defaults for both 0% and 100% saturation and closes
the Calibration Wizard.
8. Click Run. Follow the on-screen instructions to
complete the 100% calibration point.
9. When readings have stabilized, you will have several
choices:
l Select Next to continue with the zero oxygen point if
you are performing a two-point calibration. Zero point
oxygen calibration steps are listed below.
l Select Next, then Next again, then click Finish to
finalize the one-point calibration.
l Select Run to repeat the one-point calibration. Follow
steps 5-9 to repeat the calibration.
Zero Oxygen Point (0%) Calibration
Perform a 0% calibration only after completing the steps
listed above.
1. Remove the RDO sensor from the bubbler.
2. Fill the Cal Cup 1/2 full with sodium sulfite solution.
3. Submerge the RDO sensor in the solution, and
ensure there are no air bubbles on the sensing
element.
Figure 1.8 Calibrating the RDO sensor
4. Allow 15 minutes for temperature equilibration.

5. In Win-Situ 4, click Run in the Zero Oxygen Point
screen. Follow the on-screen instructions to complete
the 0% calibration point.
6. When readings have stabilized, you will have several
choices:
l Select Next, then click Finish to finalize the calibration.
l Select Back to repeat the oxygen saturation point
(100%) calibration.
l Select Run to repeat the zero oxygen point (0%)
calibration. Follows steps 5-6 to repeat the calibration.
Final Installation
1. Remove the RDO sensor from the calibration solution.
Rinse the RDO sensor thoroughly.
2. Loop the RDO cable that extends from the restrictor
cap and hold it so that it abuts the RDO sensor. See
Figure 1.9.

Restrictor Removal and TROLL 9500 Shipping
1. Grip restrictor B firmly. Remove restrictor A from the
restrictor cap. Do not allow restrictor B to rotate, as
the RDO cable can become twisted or damage the
other sensors. See Figure 1.12.
Figure 1.9 Looping the RDO cable for installation
3. Insert the RDO sensor and cable loop into the
restrictor cap, using the hole for the sensor and the
slot for the cable.
4. Push the sensor in until it snaps into the restrictor cap.
Push the cable down into the slot until a small loop
remains. See Figure 1.10.
Figure 1.10 RDO sensor and cable fully installed
5. Grip restrictor B firmly. Attach restrictor A to the
restrictor cap. Do not allow restrictor B to rotate, as
the RDO cable can become twisted or damage the
other sensors. See Figure 1.11.
Figure 1.12 Removing restrictor A —do not rotate restrictor B
2. Remove the RDO sensor and cable loop from the
restrictor cap. The end of the RDO cable will still be
attached to the TROLL 9500 body. See Figure 1.13.
Figure 1.13 RDO sensor removed from the restrictor cap
3. Grip the TROLL 9500 body firmly. Remove restrictor
B, being careful not to twist the RDO cable.
4. Remove the pH/ORP sensor by inserting the removal
tool (located in the accessories kit) underneath the
sensor. Note the sensor's port location (port 1) for
reinstallation. See Figure 1.14.

5. Remove the conductivity sensor using the removal
tool. Note the sensor's port location (port 4) for
reinstallation.
6. Remove the RDO sensor by pulling the connector out
of the TROLL 9500 body. Never remove the sensor by
pulling on the cable.
7. Reinstall all sensor port plugs.*
8. Reinstall the pH/ORP sensor and conductivity sensor.
Ensure both sensors are completely inserted.
9. Check all sensor ports. Never ship the TROLL 9500
with open sensor ports. *
10. Fill the Cal Cup with a small amount of Quick Cal
solution. Install the CalCup onto the TROLL 9500. *
