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.

The testo 890 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
The testo 890 is available in several versions, which are tailored to
various usage requirements:
• testo 890-1: high-quality wide angle lens 42° x 32°, detector 640
x 480/ 1280 X 960 pixels*, NETD < 40 mK at 30°C, 2GB SD card
for approx. 800 to 1000 images, minimum focusing distance 0.1 m,
touchscreen, built-in digital imager with power LEDs for illumination,
auto-focus, isotherm, min/max/avg on area, image stitching wizard,
laser (not available in all countries), rotatable handle, rotatable and
pivoting display
• testo 890-2, additional/different functions/features: telephoto
lens (optional), display of the surface moisture distribution
through manual entry of the environmental conditions (optional:
humidity measurement in real time with radio humidity probe),
site recognition with image management, voice recording, high
temperature measurement (optional), Full radiometric video
measurement (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
exporting.
* With SuperResolution, get four times more measurement values for
even more detailed analysis of thermal images.

4.1.3. Operating concept
The imager can be operated in two different ways.
Operation via touchscreen offers quick access to functions.
Operation via joystick requires more actions but enables single-
handed operation of the imager.
Joystick operation
Selection and activation is carried out in two steps: moving the
joystick ( [●] ) up/down/right/left moves the orange selection box on
the display. The selected function or button is activated by pressing
the joystick.

Touchscreen operation
Selection and activation is carried out in one step: the required
function or button is selected at the touch of a fingertip and is
activated at the same time.
Capacitive touchscreen. Operation is only possible with a
bare fingertip (no gloves) or a conductive stylus pen.
Illustration in this document
To carry out the basic settings, examples of both methods of
operation are given, describing all steps, see Performing basic
settings, page 22.
The other chapters only deal with functions/buttons that have to be
activated:
• Touchscreen operation: touch with a fingertip.
• Joystick operation: select first (move joystick up/down/right/left),
then activate (press joystick).

4.2.1. Power supply
The power is supplied to the instrument via a replaceable
rechargeable battery or via the mains unit provided.
With an attached mains unit, power is supplied automatically via
the mains unit and the instrument's rechargeable battery is charged
(only at ambient temperatures from 0 to 40°C).
Under high ambient temperatures a longer charging time
may be required.
Charging the battery is also possible using a desktop charging
station (accessory: 0554 8851).
The instrument is equipped with a buffer battery to maintain the
system data during an interruption in the power supply (e.g. when
the battery is changed).
