Section 5. Maintenance
• Check inside of the instrument housing to ensure against water leakage.
Any leakage will also be indicated by increase in humidity inside the
instrument housing.
• Check the dissolved oxygen probe to ensure a correct reading.
Each month
• Check wiper brush to ensure it is removing biological growth from the
dissolved oxygen membrane.
• Check humidity indicator card (or humidity readings from sensor).
Replace desiccant pack and tighten Heyco pressure fittings if needed.
• Check dissolved oxygen readings; calibrate probes if required.
Every Six Months
• Replace dissolved oxygen probe membrane and refill electrolyte solution.
Calibrate dissolved oxygen probe.
Each Year
• Check cable for rodent or environmental damage.
• Replace humidity indicator card if necessary.
Every Three to Five Years
• Check anode and cathode metals inside dissolved oxygen probe. Replace
if corrosion is extensive.
• Replace 10162 Humidity Sensor (if being used).
General Maintenance
• An occasional cleaning of the glass on the solar panel will improve its
efficiency.
• Check sensor leads and cables for cracking, deterioration, and rodent
damage.
• Check the CSBUOY-DT float, instrument housing, instrument shroud, and
cap for structural damage, poor fittings, loose fittings.
5.1.4 Calibration
The multiplier is used to calibrate the d issolved oxygen probe. The calibration
of the probe when using it as a wireless sensor in conjunction with another
datalogger is then a function of the datalogger. Generally this is made simple
by using the feature of PondView software. When using the CSBUOY-DT as
a stand-alone direct to PC connection then the multiplier is changed in the
Device Configuration Utility software.
