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 dissolved 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.
