7.1 Connecting probe
Connect temperature probe to probe socket. Observe +/-!
7.2 Switching on/off
Switch on instrument: or measurement button.
- All display segments light up briefly. The instrument changes to
the infrared mode ( lights up). The display light remains for
15 seconds every time a button is activated.
Switch off instrument: Keep pressed until display darkens.
The instrument switches off after 10min if no buttons are
activated.
7.3 Measuring
Please heed information on infrared measurement/contact
measurement.
The instrument is switched on.

11. Information on infrared measurement
11.1 Measurement method
Infrared measurement is an optical measurement
Keep lens clean.
Do not measure with clouded lens.
Keep measurement field (area between instrument and object
being measured) free of interferences: no dust and dirt
particles, no moisture (rain, steam) or gases.
Infrared measurement is a surface measurement
If there is dirt, dust, frost etc. on the surface, only the top layer will
be measured, i.e. the dirt.
In the case of shrinkwrapped foodstuffs, do not measure in air
pockets.
If values are critical, always subsequently measure using a
contact thermometer. Particularly in the food sector, the core
temperature should be measured with a penetration/immersion
thermometer.
Adaptation time
If the ambient temperature changes (change of location, e.g.
inside/outside measurement) the instrument needs an adaptation
time of 15 minutes for infrared measurement.
11.2 Emissivity
Materials have different emissivities, i.e. they emit different levels
of electromagnetic radiation. The emissivity of testo 830 is set in
the factory to 0.95. This is the ideal value for measuring non-
metals (paper, ceramics, plaster, wood, paints and varnishes),
plastics and food.
Bright metals and metal oxides are only suited to a limited extent
to infrared measurement on account of their low or nonuniform
emissivity.

11. Information on infrared measurement14
Apply emissivity enhancing layers such as varnish or emission
adhesive tape (Item no. 0554 0051) to the object being
measured. If this is not possible, measure with the contact
thermometer.
