6. Initial Operation

7.1 Connecting probe

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) without the button being pressed.

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: Laser marks the upper and lower end of the measurement spot (at distance to measurment object from 1,0 m; see chapter 11.3 measurement spot, distance). - 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 - Temperature probe was connected before the measuring instrument was switched on. 1 Position contact thermometer in/on the measurement object and activate the measurement: Press . - The instrument changes to the contact measurement mode ( lights up). The current reading is shown.

enfresitptsvnl????12 2 End the measurement: Pr ess . - 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 . Back to infrared measurement view: Press measurement button. Setting the emissivity - Instrument is in the infrared measurement mode. If no button is pressed for 3 s in the emissivity mode, the instrument switches to the infrared measurement mode. 1 Press for 3 s. 2 Set emissivity: Press or . - The instrument switches to the infrared measurement mode.

- Instrument is switched off If no button is activated in the setting mode for 3 s, the instrument changes to the next mode. 1 Press for 3 s. - The device switches to settings mode. 2 Set lower alarm value ( ALARM): Press or . Hold the button down to go forward quickly. 3 Set upper alarm value ( ALARM): Press or . Hold the button down to go forward quickly. 4 Set alarm function on / oFF: Press or . 5 Select parameter (°C / °F) : Press or . - The device returns to IR measurement view. The alarm function is only available for IR measurement. If the set alarm values are exceeded/not reached, a visual and acoustic alarm is output.

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.

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.

11.3 Measurement spot, Distance

A specific spot is determined depending on the distance from the measuring instrument to the object being measured. Measurement optics (Ratio Distance : Measurement spot)

12. Information on contact measurement

Observe minimum penetration depth in immersion/penetration probes: 10 x probe diameter Avoid applications in corrosive acids or bases. Do not use spring-loaded surface probes on sharp edges.
