Multi-Parameter
Water Quality TROLL®
TROLL 9500 Operator’s Manual 0095110 rev. 007 01/09
General Description of the Mp troll
9500
Your new Multi-Parameter TROLL 9500 water quality probe uses
the latest sensor and electronics technology to provide a robust,
durable, and user-friendly instrument.
The MP TROLL 9500 logs data from up to 7 water-level and
water-quality sensors, as well as built-in temperature and baro-
metric pressure sensors. Many custom options and versions are
available, so your instrument may not look exactly like those we
have chosen to illustrate in this manual.
The MP TROLL 9500 provides the convenience of a labora-
tory-quality measurement instrument for field use, providing true
in-situ monitoring of water level and water quality.
how to Use this ManUal
This operator’s manual is designed as both a start-up guide and
a permanent reference for the features, uses, and applications of
the Multi-Parameter TROLL 9500.

Typical usage questions and answers that we hope will help you gain
a better understanding of your new Multi-Parameter TROLL 9500
and simplify its setup and operation
UnpackinG anD inspection
Your MP TROLL 9500 was carefully inspected before shipping. Check
the instrument for any physical damage sustained during shipment.
Notify In-Situ and file a claim with the carrier if there is any such dam-
age; do not attempt to operate the instrument.
Please save packing materials for future storage and shipping of your
MP TROLL 9500. The shipping boxes have been performance-tested
and provide protection for the instrument and its accessories.
Accessories may be shipped separately and should also be inspected
for physical damage and the fulfillment of your order.
SERIAL NUMBER
The serial number is located on the large label on the Multi-Param-
eter TROLL 9500 body, and also on a small label inside the battery
compartment. The serial number is programmed into the instrument
and displayed when the instrument is connected to a PC running Win-
Situ 4 or Pocket-Situ 4. We recommend that owners keep a separate
record of this number. Should your Multi-Parameter TROLL 9500 be
lost or stolen, the serial number is often necessary for tracing and
recovery, as well as any insurance claims. If necessary, In-Situ main-
tains complete records of original owner’s names and serial numbers.
Serial numbers of the water-quality sensors are stored in sensor
memory and displayed in the software when sensors are installed.

cables
Several basic cable types are used in the MP TROLL 9500 system:
• RuggedCable™,TPU-jacketed(ThermoplasticPolyUrethane)
• ventedornon-vented
• Halogen-Freeventedornon-vented(LSZH-rated,low
smoke zero halide)
Vented cable is recommended for applications where
accurate barometric pressure measurement is required—for
example when calibrating dissolved oxygen, or for
measuring DO in percent saturation.
• VentedTefzel®*cable
• Stainless steel suspension wire for use when cable venting is not
required (e.g., with an absolute pressure sensor)
• Communicationcablesforprogrammingthedevice/downloading
the logged data
RuggedCable™
Cable includes conductors for power and communication signals, a
strength member, and a Kellems®grip to anchor the MP TROLL 9500
securely. Available in standard and custom lengths.
Uphole and downhole ends are identical bayonet-type
Twist-Lock connectors that mate with the TROLL 9500
body, TROLL Com communication cable, desiccants, and
other accessories.
Vented cable is designed for use with vented pressure/
level sensors (gauged measurements). The cable vent
tube insures that atmospheric pressure is the reference
pressure applied to the pressure sensor diaphragm.
Vented cable also enables proper functioning of the inter-
nal barometric pressure sensor, and improves dissolved
oxygen readings.
Non-vented cable may be used with non-vented pressure/
level sensors (absolute measurements), or instruments
without a pressure sensor.

CABLE DESICCANTS
Small Desiccant
Clear cap of indicating silica gel desiccant seals the uphole
end of the RuggedCable during use; protects the cable vent
tube and device electronics from condensation. The desic-
cant is blue when active. It will absorb moisture from the
top down and for best results should be replaced before the
entire volume has turned pink. Replacements are available
from In-Situ Inc. or your distributor.
Large Desiccant
The high-volume desiccant pack may last up to 20 times
longer than the small desiccant in humid environments. It
attaches to the RuggedCable in the same way. Refill kits are
available from In-Situ Inc. or your distributor.

COMMUNICATION CABLES
Comm cables interface between the TROLL 9500 and a desktop/lap-
top PC or handheld PDA for profiling, calibrating, programming, and
downloading. Both types include 0.9 m (3 ft) polyurethane cable,
external power input jack, and vent
with replaceable membrane.
TROLL Com (Cable Connect)
Connects a TROLL 9500’s Rug-
gedCable to a serial or USB port;
Weatherproof, withstands a temporary
immersion (IP67).
TROLL Com (Direct Connect)
Connects a TROLL 9500 directly to a serial or
USB port. A good choice for permanent connec-
tion to a PC, or for programming a non-vented
TROLL 9500 that will be deployed without Rug-
gedCable. Not designed for field use.

INTERNAL POWER
The MP TROLL 9500 uses:
• twostandard1.5ValkalineDcells,OR

Use only Saft LSH-20 3.6V lithium D cells. Use of any other
lithium battery will void the product warranty.
EXTERNAL POWER
A single MP TROLL 9500 can run exclusively on power supplied from
a 9 -12 VDC line power supply connected to a 90-264 VAC input.
When line power is enabled, the TROLL shuts down the battery regu-
lator, thus preserving the internal batteries. All TROLL Com models
include an external power input jack.

proviDe power
TIP: When the unit ships with a Polarographic Dissolved
Oxygen sensor installed, alkaline batteries are pre-installed
in the device to power the D.O. sensor and keep it
conditioned.
Install batteries in the Multi-Parameter TROLL 9500 as
follows:
1. Unscrew and remove the battery compartment
cover. Slide it up over the cable (if attached).
3 GettinG starteD
2. Insert two D-size batteries negative side first, positive side up.
3. Replace the battery compartment cover and tighten to compress
the o-ring seals.
Screw the cover down firmly to compress the o-rings and
create a waterproof seal. When properly assembled, the o-
rings will not be vsible.
TIP: The MP TROLL 9500 uses standard off-the-shelf 1.5V
alkaline D-cells.
Alternatively, you may use Saft LSH-20 3.6V lithium D cells.
Use of any other lithium battery will void the product
warranty.

install sensors
Basic water-quality sensors—pH or pH/ORP, polarographic D.O.,
Conductivity—may arrive installed in the instrument’s sensor ports.
Proceed to Install Software if there are no additional sensors to be
installed.
Install sensors in the Extended Sensor Set and any sensors shipped
separately as follows:
TIP: The RDO®Optical Dissolved Oxygen sensor has
special installation requirements. Please refer to the RDO
Quick Start guide, or see Section 13 of this operator’s
manual for complete information.
1. Remove the restrictor or Cal Cup from the front end of the MP
TROLL 9500.
This allows access to the sensor block depicted in the drawing
below.
There are four sensor ports, 1 – 4, plus a permanently installed
pressure and/or turbidity sensor or plug.

2. Remove the sensor’s protective cap or storage bottle and set aside
for future storage of the sensor. If the connector end is covered
with a cap, remove it also.
3. Remove any moisture or dirt from the area around
the port where you will install the sensor, then use
the sensor removal tool to remove the plug from the
port. Retain the plug for use when with fewer than 4
removable sensors installed.
4. Remove any moisture or dirt from the port connector with a clean
swab or tissue.
5. Check lubrication of the sensor o-rings.
The sensor o-rings require generous lubrication before
installation. New sensors will be lubricated at the factory. If
the o-rings appear dry, apply a silicone lubricant before
installation.
6. Align the mark on the side of the sensor with the mark on the cor-
rect port (see diagram), or visually align the sensor connector pins
with the port connector pins.
If the sensing element is at the end of the sensor, be careful
to handle the sensor by the sides. Use the insertion tool to
press the sensor into the port at step 7.
7. Press the sensor firmly into the port until you feel it
dock with the connector at the bottom.
When the sensor is properly inserted, a small gap (the
width of the sensor removal tool) remains between the
instrument body and the widest part of the sensor, for
ease of removal.
After installing a polarographic D.O. sensor, we recommend
conditioning it for 2-4 hours, preferably overnight, before
calibrating. For more on D.O. sensor conditioning, see
Section 13.
