Conduct soundings in a safe environment and in accordance with all
applicable restrictions and regulations.
WARNING
Do not use the radiosonde in an area with power lines or other
obstructions overhead. Make sure that you check the area for such
obstructions before using the radiosonde.
WARNING
Do not use the radiosonde without consultation and cooperation with
local and other applicable aviation authorities.
WARNING
Do not modify the unit in any way, except as instructed in the manual.
WARNING
Do not use the radiosonde for any purpose other than for soundings.
WARNING
The chemicals involved in an ozone sounding can be harmful, and
must be handled with proper care. To ensure your working safety, take
all the necessary precautions before beginning the preparations for a
flight. Read the sensor manuals carefully. Follow the local laboratory
work practices, regulations, and waste management guidelines. Use
disposable gloves to avoid dust and other contaminants. The gloves
must be lint-free and made of artificial fabric or plastic. RSA411
Ozone Interface Kit does not include gloves.
WARNING
Vaisala recommends the use of parachute even if it is not required by
applicable restrictions.

Precautions
Transporting RS41 Radiosondes
with Lithium Batteries
RS41 radiosondes with lithium batteries are classified as:
- UN 3091 Lithium metal batteries contained in equipment
Consignments must be packed, labeled, and documented according to
the IATA packing instructions.
When transporting the radiosondes with lithium batteries, take the
following requirements into account:
- The package must display a lithium battery handling label, see
Figure 1 on page 14 for an example. The original radiosonde
CAUTION
Do not place the lithium battery in fire or apply heat to the battery.
Do not pierce the battery with nails, strike the battery with a hammer,
step on the battery, or otherwise damage the outer casing.
Do not subject the battery pack to strong impacts or shocks.
Do not expose the battery to water or salt water, or allow the battery to
get wet.
Do not disassemble or modify the battery. The battery contains safety
and protection devices which, if damaged, may cause the battery to
generate heat, rupture or ignite.
Do not leave the battery in direct sunlight, or use or store the battery
inside cars in hot weather. Doing so may cause the battery to generate
heat, rupture, or ignite. Using the battery in this manner may also result
in shortened life expectancy and loss of performance.
Never short circuit, reverse polarity, disassemble, damage, or heat the
battery over 100 ºC (212 ºF). If an exposed lithium battery does not
start on fire, it will burn even more violently if it comes into contact
with water or even moisture in the air.
DO NOT THROW WATER ON A BURNING BATTERY. A fire
extinguisher must be used.

shipping package must be used for transport, and it already has the
lithium battery handling label.
- The consignment must include a document indicating the lithium
content, describing proper handling and procedures for damaged
packages, and a telephone number for additional information. The
original radiosonde consignment includes a SHIPPER'S
DECLARATION FOR ARTICLES NOT REGULATED AS
DANGEROUS GOODS, which should be reused for this purpose
after updating the appropriate information.

ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. Vaisala products are adequately protected against
ESD for their intended use. However, it is possible to damage the
product by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself to the equipment chassis before touching the boards.
Ground yourself with a wrist strap and a resistive connection cord.
- Always hold the boards by the edges and avoid touching the
component contacts.

Trademarks
DigiCORA® is a registered trademark of Vaisala Oyj.
CAUTION
Touch a conductive part of the equipment chassis with your other hand
before touching the boards.
Recycle all applicable material.
Dispose of batteries and the unit according to statutory regulations.
Do not dispose of with regular household refuse.

CHAPTER 2
PRODUCT AND SYSTEM COMPONENT
OVERVIEW
This chapter introduces the product and system components in more
detail.
Introduction to Ozone Sounding
An ozone sounding with RS41 consists of an ozone sensor unit,
RSA411 Ozone Interface Kit, and RS41 radiosonde. These are
described in the sections below. Other equipment needed is also
explained. For detailed information on the radiosonde, see Vaisala
Radiosonde RS41-SG and RS41-SGP User’s Guide.
In an ozone sounding, the radiosonde is attached to a styrofoam flight
box which contains the ozone sensor unit and the interface card. The
battery for powering the ozone pump is placed in a compartment on the
side of the box. For information on performing an ozone sounding with
Vaisala Radiosonde RS41, see also the MW41 on-line help, embedded
in the sounding system software.

Ozone Sensor Unit
The ozone sensor unit is either of the following:
- Science Pump Corporation (SPC) Model ECC-6A ozone sensor
- Droplet Measurement Technologies (DMT) Model Z ozone sensor
The sensors are based on chemical reaction cells. The type of the
sensors is electrochemical concentration cell (ECC). Air is sampled
flow (by using a pump) and it goes to a reaction cell, in which the
sampled ozone reacts in a solution, and the current developed in the
reaction is detected and measured with an ozone interface. The ozone
sensor units are thoroughly discussed in the sensor manufacturers’
manuals (see section Related Manuals on page 11) and Performance
Review Literature listed in Appendix D Performance Review Literature
on page 119.
The main parts of an SPC ECC-6A ozone sensor are seen in Figure 2 on
page 19. Model Z ozone sensor is similar to the SPC sensor. Refer to the
sensor manufacturer’s manuals for more detailed information.
