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, testo 880 may not be pointed at the sun or
other high-radiation sources (e.g. objects with temperatures
higher than 500 °C). This can lead to serious damage to the
detector. Damage caused in this way to the microbolometer
detector is excluded from warranty coverage.
> The objects to be measured or the measurement
environment may also pose risks: 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 the rechargeable battery 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 measuring instrument or the
recommended charging station.
• 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.

automatically via the mains unit and the instrument's
rechargeable battery is charged (only at ambient temperatures
from 0 to 45 °C).

4 Product description
14
Charging the battery is also possible using a desktop charging
station (accessory).
The instrument is equipped with a buffer battery (type CR 1632)
to maintain the system data during an interruption in the power
supply (e.g. when the battery is changed).
File formats and file names
The images are saved according to the following pattern:
XX_YYYYY.ZZZ
XX: IR for infrared image without attached real image and for
surface moisture image, IV for infrared image with attached real
image, VI for real image.
YYYYY: 5-digit consecutive number
ZZZ (file extension): BMT for infrared image with/without
attached real image and for surface moisture image, BMP for
real image.
The file names can be changed using the PC and software
Windows Explorer.
