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.
