Getting started
Before using this device in the classroom, you will need to
charge the battery, install data collection software, and check for
a firmware update.
Charge the battery
The Wireless Optical Dissolved Oxygen Sensor’s rechargeable
battery should be charged before using the sensor for the first
time, as the sensor is not shipped with a full charge. Charge the
battery by connecting the micro USB port to any standard USB
charger. The Battery Status LED is solid yellow while charging.
When fully charged, the LED changes to solid green.
Get the software
You can use the sensor with SPARKvue or PASCO Capstone
software. If you’re not sure which to use, visit
pasco.com/products/guides/software-comparison.
SPARKvue is available as a free app for Chromebook, iOS, and
Android devices. We offer a free trial of SPARKvue and
Capstone for Windows and Mac. To get the software, go to
pasco.com/downloads or search for SPARKvue in your device’s
app store.
If you have installed the software previously, check that you have
the latest update:

create a new blank graph display.
2. To assign measurements to the graph’s axes, click each
<Select Measurement> box and select an appropriate
measurement from the list.
3. When you are ready, click Record to begin collecting
data.
Collecting data
Taking measurements
Once the sensor is connected to PASCO Capstone or
SPARKvue, create a display to measure DO2Concentration.
Remove the rubber boot to uncover the sensor cap. Place the
probe into a water sample to a depth of at least one inch. (For
best temperature compensation, fully immerse the stainless
steel portion of the probe.) When you are ready, begin collecting
data.
Measure oxygen gas concentration in air
The Wireless Optical Dissolved Oxygen Sensor was specifically
designed to be used in water. However, reasonably good
qualitative results may be obtained in air. Oxygen gas
concentration in air is calculated by taking the DO2Saturation
value from the sensor and multiplying it by 20.9%, which is the
assumed partial pressure contribution of O2in air. Best accuracy
will be achieved in high humidity environments. Long-term
measurements in dry air are not recommended, as this will dry
out the probe sensor cap.
IMPORTANT: The probe should not be used in
an environment with flammable, caustic, or
corrosive gases.
To use the sensor in air, follow the same instructions as using
the sensor in water, except select O2Gas Concentration as the
measurement.

Calibration
The Wireless Optical Dissolved Oxygen Sensor is calibrated at
the factory and does not need to be recalibrated under most
circumstances. However, if needed, the sensor can be calibrated
using one or two known standards. For more information on
calibrating the sensor, see the PASCO Capstone or SPARKvue
online help.
Care and maintenance
The sensor cap will degrade over time with use. The working life
of the sensor can be extended by keeping the cap clean and
properly stored between uses.
Storage
The sensor cap should not be allowed to dry out. Moisten the
sponge inside the rubber boot with distilled water and cover the
sensor cap with the boot. Gently push the rubber boot against
the end of the probe to ensure that the sponge is in contact with
the sensor cap. Do not store the probe in water, as that can
encourage algae growth on the probe.
Cleaning
To clean the sensor cap, rinse it with clean water and dry it with
a lint-free cloth. A mild detergent may be used if necessary. Do
not use alcohols or other organic solvents that may deteriorate
the sensing layer.
Sensor cap replacement
The sensor cap may need to be replaced if it is no longer
responsive. It should also be replaced if it becomes cracked,
scratched, or damaged. A Replacement Cap (PS-3250) can be
purchased from PASCO. Contact Technical Support to
determine whether a replacement sensor cap is needed.
NOTE: When installing a replacement cap, you
must set the appropriate calibration coefficients
for the cap in the software. For information on
this, see the manual for the cap or the PASCO
Capstone or SPARKvue online help.
