Section 2. CSBUOY-DT Description

The CSBUOY-DT is designed to eliminate the use of hard-wire cable to
connect the dissolved oxygen and water temperature sensors with the
datalogger (CR510, CR10X, CR23X, CR800, CR850, CR1000, CR3000).
Operation is simplified through a modular design, prewired sensors, and

Section 3. CSBUOY Installation

3.1 Site Selection

The site should represent the general area being measured. Placement should
allow the buoy to float freely without obstruction from the bottom of the water
compound being monitored. The buoy solar panel should not have any
obstruction from full sunlight. Keep away from overhanging trees or other
obstructions. The solar panel should be angled towards the south to maximize
full solar capabilities.

Ensure that each wire is in the proper place on the CR206. Connect the battery
cable to the battery. Using a wrench, tighten the Heyco Pressure fitting to
ensure a watertight seal around the sensor cables exiting the instrument

housing. Insert the instrument mounting bracket into the instrument
housing, paying particular attention that the cable are not pinched. Tighten the
instrument housing lid.

With a wrench, tighten the vent plug into the float.

Attach the solar panel to the solar panel brackets. Tighten the connection
with the thumb screws.

Section 4. Communication

The CSBUOY-DT can be used as a stand-alone monitoring system that
communicates directly with the PC, or as a wireless sensor that is integrated
with other Campbell Scientific dataloggers (CR510, CR10X, CR23X, CR800,
CR850, CR1000, CR3000) with table-based operating systems using the
PakBus communication protocol.

4.1 Direct Connection to PC

In order to communicate with the CSBUOY-DT directly from the PC:

1. Device Configuration Utility software must be installed in the PC.

2. An RF401 Spread Spectrum Radio must be connected via com port to the

PC.

3. The RF401 and CSBUOY-DT Transceiver (CR206) must be configured to

communicate with each other (refer to RF401 and CR206 manuals).

4.1.1 Device Configuration Utility Software Installation

Refer to the Device Configuration Utility Manual for installation an d operation
instructions.

4.1.2 RF401 Connection

Refer to the RF401 Manual for configuration instructions.

4.2 CSBUOY-DT as a Wireless Sensor

A CSBUOY-DT acting as a wireless sensor can communicate with a CR800,
CR850, CR1000, or CR3000 datalogger using the GetVariable instruction.
With a CR10X, CR510, or CR23X, the program instruction P193 is used.
These instructions open the communication between CSBUOY-DT and the
datalogger allowing data to be sent and received. In addition to this
instruction:

1. The datalogger requires a RF401 Spread Spectrum Radio configured with

a datalogger CDSC current port configuration.

2. The RF401 connected to the datalogger and the CSBUOY-DT must be

configured with the same radio address, net address and hopping
sequence.

Section 5. Maintenance

The CSBUOY-DT has been engineered to provide many years of reliable
service. However, periodic maintenance is required to help ensure that the
system performs up to its potential. Equipment must be in good operating
condition, which requires a program of regular inspection and maintenance.
Routine and simple maintenance can be accomplished by the person in charge
of the CSBUOY-DT.

5.1 Instrumentation Maintenance

The instrumentation requires a minimum of routine maintenance. A few
preventative maintenance steps will optimize battery life and decrease the
chances of system failure.

5.1.1 Batteries

The CSBOUY-DT has been programmed to record battery voltage. This will
allow the user to determine how long a fresh battery will last. The
CSBUOY-DT is supplied with a fresh 12 VDC, 7.0 Ahr rechargeable battery.
This battery is continually recharged by the 5-watt solar panel mounted on top
of the instrument housing. Be aware of battery voltage that consistently
decreases over time, which indicates a failure in the charging circuitry.

5.1.2 Desiccant

Damage to the CR206 and wiring panel will occur if high moisture levels
inside the CSBOUY-DT instrument housing are not corrected. Enclosure
humidity is monitored by a humidity indicator card provided with the
CSBUOY-DT. It can also be more accurately monitored using the 10162
Enclosure Humidity Sensor, which is an optional sensor that can be purchased
with the CSBUOY-DT. The CSBOUY-DT is programmed to provide data
from this sensor.

Regardless if the humidity sensor or the humidity indicator card is used to
monitor humidity inside the instrument housing, desiccant packs should be
replaced when relative humidity inside the instrument housing exceeds 35%.

5.1.3 Sensor Maintenance

Sensor maintenance should be performed at regular intervals, depending on the
desired accuracy and the conditions of use. A suggested maintenance schedule
is outlined below.

First week

• Check the wiper brush to ensure it is removing biological growth from the

dissolved oxygen sensor membrane.

• Check the Heyco pressure seals to ensure a tight fit.

5-1

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

• Replace 10162 Humidity Sensor (if being used).

General Maintenance

• An occasional cleaning of the glass on the solar panel will improve its

cap for structural damage, poor fittings, loose fittings.

5-2

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.

5.1.4.1 Air Calibration

1. Place the dissolved oxygen probe in the air, shaded from the sun. Wait for

the measurement reading to stabilize. This may take 15 minutes or more.

2. Determine the air temperature (use the temperature reading from the

probe; this is found on the Device Configuration Utility screen) and the
barometric pressure(preferred) or elevation.

3. Using the calibration chart determine the oxygen concentration in the air.

4. Use the following equation to calculate the multiplier:

M = P/R
M = Multiplier
P = Concentration in PPM of the air (from calibration chart).
R = The signal output in mV of the dissolved oxygen probe.

5. Enter the multiplier in Device Configuration Utility or LoggerNet from the

calculated number.

5.1.4.2 Hand Calibration

Section 5. Maintenance

1. Use a hand-held dissolved oxygen meter to determine the correct

concentration of dissolved oxygen in the water (the accuracy of the
method will be dependent upon the accuracy of the hand held device).

2. Use the following equation to calculate the multiplier:

M = D/R
M = Multiplier
D = measured dissolved oxygen in PPM.
R = The signal output in mV of the dissolved oxygen probe.

3. Enter the multiplier in Device Configuration Utility or LoggerNet from the

calculated number.
