3.2 Power supply
The power is supplied to the instrument via a replaceable rechargeable battery
or the mains unit provided (battery must be inserted).
With an attached mains unit, power is supplied automatically via the mains unit
and the rechargeable battery is charged (only at ambient temperatures from 0 to
40°C). Operation is possible with the mains unit connected.
It is also possible to charge the battery using a charging station (accessory).
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).

4.1 Commissioning
Please refer to the commissioning instructions supplied for testo 865s, 868s,
871s, 872s (0973 8723).

Switching on the camera
1
- Remove protective cap from the lens.
2
- Press .

The camera starts.

The start screen appears on the
display.
To ensure measuring accuracy, the camera performs automatic zeroing
approx. every 60 s. A “click” is heard when this happens. The image
freezes briefly when this occurs. Zeroing is carried out more frequently
during the camera warm-up period (takes approx. 90 seconds).
During the warm-up period no measuring accuracy is guaranteed. The
image can already be used for indication purposes and saved.

6Performing the measurement
CAUTION
High thermal radiation (e.g. due to sun, fire, furnaces)
Detector may be damaged!
-Do not point the camera at objects with temperatures > 650 °C.
Ideal framework conditions
•Building thermography, investigating the building shell:
Considerable temperature difference between inside and outside required
(ideal: ≥ 15 °C / ≥ 27 °F).
•Consistent weather conditions, no intensive sunlight, no precipitation, no
strong wind.
•To ensure maximum accuracy, the camera requires an adjustment time of
10 minutes after it is switched on.
Important camera settings
•Emissivity and reflected temperature must be set correctly in order to
precisely determine the temperature. Subsequent adjustment is possible via
the PC software, if required.
•When auto-scaling is activated, the colour scale is continuously adjusted to
the min./max. values of the current measurement image. This means that
the colour assigned to a specific temperature is changing constantly! To be
able to compare multiple images based on the assigned colour, scaling must
be set manually to fixed values, or must be subsequently adjusted to uniform
values using the PC software.
