4 Product-specific information
Damage to the detector!
During operation, this instrument must not be pointed at the sun or other
intensive sources of radiation (e.g. objects with temperatures exceeding
650 °C). This can cause serious damage to the detector. The manufacturer
does not provide any warranty for any such damage to the microbolometer
detector.

7.1 Use
The testo 883 is a handy, robust thermal imager. You can use it to undertake
the non-contact measurement and display of surface temperature distribution.
Areas of application
• Preventive maintenance / servicing: Electrical and mechanical inspection of
systems and machines
• Building inspection: Energy efficiency rating of buildings (heating, ventilation,
air-conditioning trade, building engineers, engineering firms, experts)
• Production monitoring / quality assurance: monitoring of production

7.2 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
35 °C).
It is also possible to charge the battery using a charging station (accessory).
To maintain system data during a power interruption (e.g. when changing the
battery), the data is stored temporarily.

Rechargeable battery care
• Do not fully exhaust rechargeable batteries.
• Store rechargeable batteries only when charged and at low temperatures,
but not below 0 °C (best storage conditions are 50-80% charge, at an
ambient temperature of 10-20 °C, recharge completely before using again).
• For longer breaks, you should discharge and recharge the batteries every 34 months. Trickle charging should not exceed 2 days.

Emissivity information:
The emissivity describes the capability of a body to emit electromagnetic
radiation. This is material-specific and must be adapted for correct
measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings), plastics and
food have high emissivity, which means that the surface temperature can be
easily measured using infrared.
Because of their low or non-uniform emissivity, bright metals and metal oxides
only have limited suitability for infrared measurement. Highly inaccurate
measurements should be expected. A remedy for this is coatings that increase
emissivity, e.g. paint or emission adhesive (accessory: 0554 0051), which must
be applied to the object to be measured.
The following table gives typical emissivities of important materials. These
values can be used as a guide for user-defined settings.

Material (material temperature) Emissivity
Reflected temperature information:
Using this offset factor, the reflection is calculated out based on the low
emissivity, and the accuracy of the temperature measurement with infrared
measuring instruments is improved. In most cases, the reflected temperature is
identical to the ambient air temperature. Only when objects with strong
emissions at much lower temperatures (such as cloudless skies during outdoor
readings) or much higher temperatures (such as ovens or machines) are in
proximity to the object being measured should the radiation temperature of
these sources be determined and used. The reflected temperature has little
effect on objects with high emissivity.
