Frequently Asked Questions - 830 Testo

How do I perform an infrared measurement with the Testo 830?

Turn on the device by pressing the measurement button. Aim at the object with the laser while holding the button. The laser marks the measurement area. Release the button to freeze the value (HOLD). Min/max values are stored until the next measurement.

How to adjust emissivity for specific materials?

In infrared mode, hold the button for 3 seconds to enter emissivity adjustment. Use the ▲/▼ buttons to adjust the value from 0.1 to 1.0. The default value is 0.95, suitable for most non-metallic materials.

How to change the battery?

Turn off the device. Open the battery compartment by removing the cover. Remove the old battery and insert a new 9V battery, respecting polarity (+/-). Close the compartment.

What does the display "---" mean?

In infrared mode, "---" indicates that the measured temperature is outside the measurement range (-30 to +400 °C). In contact mode, this means the range is exceeded, no probe is connected, or the probe is damaged.

How to clean the lens?

Gently clean the lens with water or a cotton swab moistened with medical alcohol. For the housing, use a damp cloth. Do not use abrasive solutions.

What is the optimal distance for an infrared measurement?

The optics have a 30:1 ratio. For example, at 1 meter distance, the diameter of the measurement area is about 33 mm (30:1). The further you are, the larger the measured area.

Can I measure shiny or metallic surfaces with infrared?

Shiny or oxidized metallic surfaces have too low emissivity for reliable infrared measurement. Use adhesive tape to increase emissivity or prefer a contact thermometer.

How to use the contact probe?

Connect the type K probe to the device before turning it on. Press the measurement button to switch to contact mode. Place the probe on the object to measure. The value is displayed. Press again to freeze the value (HOLD).

How to set the temperature alarms?

Turn off the device. Hold down the button for 3 seconds to enter settings. Use ▲/▼ to set the lower limit (ALARM L) and upper limit (ALARM H). Enable or disable the alarm using ▲/▼. The audible and visual alarm triggers when exceeded.

What to do if the screen does not turn on or the backlight becomes dim?

This indicates a weak battery. Replace the battery with a new 9V battery. If the problem persists, check the battery contacts.

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 nonmetals (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.
