2.2. Ensure safety
> Only operate the product properly, for its intended purpose and
within the parameters specified in the technical data. Do not
use any force.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
During operation, the imager must not be pointed at the sun or
other intensive sources of radiation (e.g. objects with temperatures
greater than 550°C/1022°F, if using the high-temperature
measurement range 1400°C/2552°F). This can lead to serious
damage to the detector. The manufacturer assumes no liability for
any such damage to the microbolometer detector.
> Dangers may also arise from the systems being measured or
the measuring environment: Note the safety regulations valid in
your area when performing the measurements.
> Do not store the product together with solvents. Do not use any
desiccants.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow the
prescribed steps exactly. Use only original spare parts
from Testo.
> Improper use of rechargeable batteries can lead to destruction
or injuries by means of current surges, fire or escaping
chemicals. The following instructions must be observed to avoid
such hazards:
• Only use in accordance with the directions in the instruction
manual.
• Do not short, take apart or modify.
• Do not expose to heavy impacts, water, fire or temperatures
above 60 °C.
• Do not store in the proximity of metal objects.
• Do not use leaky or damaged rechargeable batteries. In the
event of contact with battery acid: Thoroughly wash affected
area with water and consult a doctor, if necessary.
• Only charge in the instrument or the recommended charging
station.

2 Safety and the environment

• Immediately stop the charging process if this is not
completed in the given time.
• In the event of improper function or signs of overheating,
immediately remove the rechargeable battery from the
measuring instrument/charging station. Caution:
Rechargeable battery may be hot!
2.3. Protecting the environment
> Dispose of faulty rechargeable batteries/spent batteries in
accordance with the valid legal specifications.
> At the end of its useful life, send the product to the separate
collection for electric and electronic devices (observe local
regulations) or return the product to Testo for disposal.

3.1. Use
The testo 885 is a handy and robust thermal imager. It enables you
to carry out contactless determination and display of the
temperature distribution on surfaces.
Typical areas of application are:
• Building inspection: energetic assessment of buildings, and
inspection of heating, ventilation and air conditioning systems.
• Preventative maintenance (servicing): mechanical and electrical
inspection of systems, machines and energy distribution
systems
• Production monitoring (quality assurance): monitoring of
production processes
• Professional energy consultation, leak detection
• Checking of photovoltaic modules
• Additional/different functions/features: telephoto lens (optional),
super-telephoto lens (optional), 25° lenses (optional), display of
surface moisture distribution via manual input of the ambient
conditions (optional: humidity measurement in real time with
radio humidity probe), SiteRecognition (site recognition with
image management), voice recording, high temperature
measurement (optional), process analysis package - sequence
capturing in the camera and video measurement on the PC
(optional)
Export control
Thermal imagers may be subject to the export restrictions of the
European Union.
Please observe the national regulations for export control when

FCC Warnings
Information from the FCC (Federal Communications Commission)
For your own safety
Shielded cables should be used for a composite interface. This is to ensure continued
protection against radio frequency interference.
FCC warning statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is c onnected.
• Consult the dealer or an experienced radio/TV technician for help.
Caution
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment. Shielded interface cable must be
used in order to comply with the emission limits.
Warning
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
