INTRODUCTION
Thank you for purchasing the EcoSense ODO200/ODO200M, a precise
handheld instrument that measures temperature and dissolved oxygen
in % and mg/L.The EcoSense ODO200/ODO200M measures dissolved
oxygen in water using optical, lifetime luminescence technology and
uses a digital signal to send information between the instrument and
probe. Key advantages of the EcoSense ODO200/ODO200M include
the elimination of sensor flow dependence (stirring) and sensor warm-
up time, greater stability, less frequent calibrations, and the elimination
of frequent membrane/electrolyte changes. This instrument uses one
9V battery.
Key differences between the YSI ODO200 and ODO200M include:
• ODO200 can store 50 data sets, while the ODO200M can store
250 data sets.
• A real-time clock is included on the ODO200M for date/time stamp
of saved data.
• The ODO200M features a waterproof USB port with cover that will
allow customers to download stored measurement data to a PC.
• A recal prompt on the ODO200M allows users to select a
recalibration interval.

INITIAL INSPECTION
Carefully unpack the instrument and accessories and inspect for
damage. Compare received parts with items on the packing list. If any
parts are damaged or missing, contact YSI Customer Service at 800-
897-4151 ([phone]) or the authorized YSI distributor where
the instrument was purchased.
PRECAUTIONS
THE PROBE
Sensor caps last longer if stored in a moist environment and kept clean
and free of scratches in the paint layer. Erratic readings can result from
damaged or dirty caps. If unstable readings occur from large scratches
in the paint or dye layer, replace the sensor cap. See the Maintenance
and Troubleshooting section of this manual for information on how to
clean or replace the sensor cap. The average sensor cap replacement
interval is 12 to 18 months, although they may last longer.
Avoid substances that may damage probe materials such as
concentrated acid, caustics and strong solvents. Probe materials
include urethane (cable), Xenoy (probe body), acrylic (sensor cap) and
acetal and stainless steel (probe guard).
To prevent the sensor cap from drying out, store the probe in the gray
calibration/storage sleeve with a moistened, clean sponge. In the event
the sensor cap dries out, rehydrate it following the instructions in the
Maintenance and Troubleshooting section of this manual.
INITIAL SETUP
Throughout the manual, the term “probe” refers to the end of the cable
where the sensor is located, the term “sensor” refers to the Optical
Dissolved Oxygen sensing portion of the cable/probe assembly, and
the term “sensor cap” refers to the removable sensing cap that is
replaced about once per year (Figure 1).

PREPARING THE PROBE
Each sensor cap has unique calibration coefficients associated with it.
These coefficients are labeled on the instruction sheet included with
each EcoSense cable/probe assembly and replacement sensor cap.
Remove the probe/cable assembly from the shipping container and
locate the sensor cap instruction sheet. Be sure to save the instruction
sheet in case you need to reload these calibration coefficients.
New probe/cable assemblies have the sensor cap installed and
coefficients loaded into the probe at the factory. When a cable is
installed, the coefficients are automatically sent to the instrument.
Preparing the probe for the first time:
1. Remove the probe guard from the probe by turning it
counterclockwise.
2. Remove the red storage cap which contains a moist sponge from
the end of the probe by pulling it straight off the sensor. Save this
to use later for long term storage.
3. Reinstall the probe guard by sliding it carefully over the sensor and
then threading it onto the cable/probe assembly with a clockwise
rotation (Figure 2).
4. Locate the gray calibration/storage sleeve that was shipped with
your probe/cable assembly. Moisten the sponge in the gray
calibration/storage with a small amount of clean water.
5. Slide the calibration/storage sleeve over the probe guard to keep
the probe in a moist environment for storage and calibration
(Figure 3). It is important to always keep your sensor in a moist
environment so the sensor cap does not dry out.

6. Connect the cable to the instrument by aligning the connectors,
pushing them together and then screwing down the retainer
clockwise.

BATTERY INSTALLATION
To install (or replace) the battery, remove
the two battery cover screws and battery
cover. Replace the 9V battery. Replace the
battery cover and o-ring (be sure to align
the o-ring correctly to prevent a bad seal)
and fasten the two battery cover screws.
An initial display of “LOW BAT” on the
LCD indicates approximately one hour of
battery life for unit operation within specifications. Replace battery
when “LOW BAT” appears on the LCD.
Battery Disposal
This instrument is powered by a 9 volt battery, which the user must
remove and dispose of when the battery no longer powers the
instrument. Disposal requirements vary by country and region, and
users are expected to understand and follow the battery disposal
requirements for their specific locale.
