6. Initial Operation
▶ Insert battery: See 9.1 Changing the battery.
7. Operation
7.1 Connecting probe (testo 830-T2 only)
▶ Connect temperature probe to probe socket. Observe +/-!
7.2 Switching on/off
▶ Switch on instrument: Press measurement button.
- All display segments light up briefly. The instrument changes to the infrared mode (lights up).
The display light remains for 10 seconds every time a button is activated.
▶ Switch off instrument: Keep pressed until display darkens.
The device switches off automatically after 1 min (IR measure - ment view) or 10 mins (contact measurement view, only testo 830-T2) without the button being pressed.
7.3 Measuring
! Observe information on infrared measurement (chapter 11) / contact measurement (chapter 12).
! With IR measurement, the min./max. values are reset by pressing the measurement button, and with contact measurement, this is done when the device is switched off or when you switch to the IR measurement view.
- The instrument is switched on.
Infrared measurement
1 Start measurement: Hold down measurement button.
2 Locate object to be measured using laser point. testo 830-T1: laser marks the centre point of the measurement spot. testo 830-T2: Laser marks the upper and lower end of the measurement spot.
- The current reading is shown (2 measurements per second)
3 End measurement: Release button.
- HOLD lights up. The last measured value and min./max. value are saved until the next measurement.
▶ Switch between min., max. and recorded value: Press ▲
▶ Restart measurement: Press measurement button.
Contact measurement (testo 830-T2 only)

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.
- 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.
