Precautions

DANGER — MANY HAZARDS ARE ASSOCIATED WITH INSTALLING, USING, MAINTAINING, AND WORKING ON OR AROUND

TRIPODS, TOWERS, AND ANY ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS, ENCLOSURES,
ANTENNAS, ETC. FAILURE TO PROPERLY AND COMPLETELY ASSEMBLE, INSTALL, OPERATE, USE, AND MAINTAIN TRIPODS,

TOWERS, AND ATTACHMENTS, AND FAILURE TO HEED WARNINGS, INCREASES THE RISK OF DEATH, ACCIDENT, SERIOUS
INJURY, PROPERTY DAMAGE, AND PRODUCT FAILURE. TAKE ALL REASONABLE PRECAUTIONS TO AVOID THESE HAZARDS.
CHECK WITH YOUR ORGANIZATION'S SAFETY COORDINATOR (OR POLICY) FOR PROCEDURES AND REQUIRED PROTECTIVE
EQUIPMENT PRIOR TO PERFORMING ANY WORK.

Use tripods, towers, and attachments to tripods and towers only for purposes for which they are designed. Do not exceed design
limits. Be familiar and comply with all instructions provided in product manuals. Manuals are available at www.campbellsci.com or
by telephoning [phone] (USA). You are responsible for conformance with governing codes and regulations, including safety
regulations, and the integrity and location of structures or land to which towers, tripods, and any attachments are attached. Installation
sites should be evaluated and approved by a qualified engineer. If questions or concerns arise regarding installation, use, or
maintenance of tripods, towers, attachments, or electrical connections, consult with a licensed and qualified engineer or electrician.

General

• Prior to performing site or installation work, obtain required approvals and permits. Comply

with all governing structure-height regulations, such as those of the FAA in the USA.

• Use only qualified personnel for installation, use, and maintenance of tripods and towers, and

any attachments to tripods and towers. The use of licensed and qualified contractors is highly
recommended.

• Read all applicable instructions carefully and understand procedures thoroughly before

beginning work.

• Wear a hardhat and eye protection, and take other appropriate safety precautions while

working on or around tripods and towers.

• Do not climb tripods or towers at any time, and prohibit climbing by other persons. Take

reasonable precautions to secure tripod and tower sites from trespassers.

• Use only manufacturer recommended parts, materials, and tools.

Utility and Electrical

• You can be killed or sustain serious bodily injury if the tripod, tower, or attachments you are

installing, constructing, using, or maintaining, or a tool, stake, or anchor, come in contact with
overhead or underground utility lines.

• Maintain a distance of at least one-and-one-half times structure height, 20 feet, or the distance

required by applicable law, whichever is greater, between overhead utility lines and the
structure (tripod, tower, attachments, or tools).

• Prior to performing site or installation work, inform all utility companies and have all

underground utilities marked.

• Comply with all electrical codes. Electrical equipment and related grounding devices should

be installed by a licensed and qualified electrician.

Elevated Work and Weather

• Exercise extreme caution when performing elevated work.

• Use appropriate equipment and safety practices.

• During installation and maintenance, keep tower and tripod sites clear of un-trained or non-

essential personnel. Take precautions to prevent elevated tools and objects from dropping.

• Do not perform any work in inclement weather, including wind, rain, snow, lightning, etc.

Maintenance

• Periodically (at least yearly) check for wear and damage, including corrosion, stress cracks,

frayed cables, loose cable clamps, cable tightness, etc. and take necessary corrective actions.

• Periodically (at least yearly) check electrical ground connections.

WHILE EVERY ATTEMPT IS MADE TO EMBODY THE HIGHEST DEGREE OF SAFETY IN ALL CAMPBELL SCIENTIFIC PRODUCTS,
THE CUSTOMER ASSUMES ALL RISK FROM ANY INJURY RESULTING FROM IMPROPER INSTALLATION, USE, OR
MAINTENANCE OF TRIPODS, TOWERS, OR ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS,
ENCLOSURES, ANTENNAS, ETC.

CS215 Temperature and Relative
Humidity Probe

1. Introduction

The CS215 Temperature and Relative Humidity Probe is designed for general
meteorological and other data logging applications. It uses the SDI-12
communications protocol to communicate with any SDI-12 recorder,
simplifying installation and programming.

Before using the CS215, please study

• Section 2, Cautionary Statements

• Section 3, Initial Inspection

• Section 4, Quickstart

2. Cautionary Statements

• READ AND UNDERSTAND the Precautions section at the front of this

manual.

• When opening the shipping package, do not damage or cut the cable

jacket. If damage to the cable is suspected, consult with a Campbell
Scientific application engineer.

• Although rugged, the CS215 should be handled as a precision scientific

instrument.

• Santoprene® rubber, which composes the black outer jacket of the CS215

cable, will support combustion in air. It is used because of its resistance to
temperature extremes, moisture, and UV degradation. It is rated as slow
burning when tested according to U.L. 94 H.B. and passes FMVSS302.
However, local fire codes may preclude its use inside buildings.

3. Initial Inspection

• Check the packaging and contents of the shipment. If damage occurred

during transport, immediately file a claim with the carrier. Contact
Campbell Scientific to facilitate repair or replacement.

• Check model information against the shipping documents to ensure the

expected products and the correct lengths of cable are received. Model
numbers are found on each product. On cables and cabled items, the
model number is usually found at the connection end of the cable. Report
any shortages immediately to Campbell Scientific.

4. Quickstart

Short Cut is an easy way to program your datalogger to measure the CS215
sensor and assign datalogger wiring terminals. Use the following procedure to
get started.

1. Install Short Cut by clicking on the install file icon. Get the install file

from either www.campbellsci.com, the ResourceDVD, or find it in
installations of LoggerNet, PC200W, PC400, or RTDAQ software.

2. The Short Cut installation should place a shortcut icon on the desktop of

your computer. To open Short Cut, click on this icon.

3. When Short Cut opens, select New Program.

4. Select Datalogger Model and Scan Interval. Click Next.

CS215 Temperature and Relative Humidity Probe

5. Under the Available Sensors and Devices list, select the Sensors |

Meteorological | Relative Humidity & Temperature folder. Select

CS215 Temperature & Relative Humidity Sensor. Click to move

the selection to the Selected device window. Data defaults to degree
Celsius. This can be changed by clicking the Deg C box and selecting
Deg F, for degrees Fahrenheit, or K for Kelvin.

6. After selecting the sensor, click at the left of the screen on Wiring

Diagram to see how the sensor is to be wired to the datalogger. The
wiring diagram can be printed out now or after more sensors are added.

7. Select any other sensors you have, then finish the remaining Short Cut

steps to complete the program. The remaining steps are outlined in Short

Cut Help, which is accessed by clicking on Help | Contents |
Programming Steps.

8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the

PC to datalogger connection is active, you can click Finish in Short Cut
and you will be prompted to send the program just created to the
datalogger.

9. If the sensor is connected to the datalogger, as shown in the wiring

diagram in step 6, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.

5. Overview

The CS215 probe uses a single chip element that incorporates both a
temperature and an RH sensor. Each element is individually calibrated with
the calibration corrections stored on the chip. The element is easily changed in
the field. The ability to replace the element in the field reduces downtime and
calibration costs.

Electronics within the CS215 control the measurement made by the sensor
element, apply temperature and linearization corrections to the readings, and
present the data via SDI-12 to a datalogger.

A sintered plastic filter minimizes the effects of dust and dirt on the sensor.
The filter is lightweight and hydrophobic, thereby diminishing its effect on the
time response of the sensor.

The probe housing is designed to withstand permanent exposure to all weather
and to fit into a range of radiation shields, including compact shields.
