Frequently Asked Questions - 270 Testo

How do I change the batteries of the Testo 270?

Loosen the battery compartment screws with a flathead screwdriver, open the cover, insert 2 AAA batteries observing polarity, close and tighten the screw.

How do I switch from contact measurement to infrared measurement?

Press the [ ] key to switch from contact measurement to IR measurement, and the [ ] key for the reverse.

What does the '---' display on the screen mean?

The '---' display indicates that the measured value is outside the admissible measuring range. Check that the object is within the specified range.

How do I clean the Testo 270 thermometer?

Use neutral cleaning solutions or an alcohol-based disinfectant. Clean the housing and probe with running water, wipe with a cloth. For the lens, use a cotton swab moistened with water or medical alcohol.

How do I set the emissivity for infrared measurements?

In IR measurement mode, press and hold the [ ] and [ ] keys simultaneously until the emissivity flashes. Change the value with [ ] or [ ] and wait 3 seconds to confirm.

How do I activate the AutoHold function?

Turn off the device, press and hold [ ] and [ ] until 'AutoHold' or 'Hold' flashes. Use [▲] or [▼] to select 'AutoHold' (activation) or 'Hold' (deactivation).

What should I do if the device does not turn on?

Check the batteries: if they are empty, replace them with new AAA batteries observing polarity. If the problem persists, contact Testo after-sales service.

How do I interpret the laser points during an infrared measurement?

The laser points mark the lateral limit of the measuring range. The measured area lies between the points; the greater the distance, the wider the area (10:1 optics).

How do I store the Testo 270 thermometer?

Store it in a dry place at a temperature between -30 and +70 °C without batteries. Avoid solvents and shocks.

How do I check the calibration of the thermometer?

According to standard EN 13485, it is recommended to check and calibrate the device annually according to standard EN 13486. Contact Testo for calibration service.

11. Information on infrared (IR) measurement

11.1 Measuring method

IR measurement is a visual measurement

▶ Keep lens clean.
▶ Do not carry out measurement with a foggy lens.
- Keep the measuring range (the range between the instrument and the measurement object) free of obstacles. There must be no particles of dust or dirt, no humidity (rain, steam) and no gases.

IR measurement is a surface measurement

If there is dirt, dust, frost, etc. on the surface, only the outermost layer is measured, i.e. the dirt.

For vacuum-packed food, do not measure at air pockets.
Where the values are critical, always measure separately with a contact thermometer. Particularly in the food sector: measure core temperature with a penetration/immersion thermometer.

Adjustment time

If the ambient temperature changes (change of location, e.g. measurement indoors/outdoors), the instrument must be allowed to equalise for 15 minutes for infrared measurement.

11.2 Emissivity

Materials have different emission levels. This means they emit various amounts of electromagnetic radiation. The emission level of the instrument has a default setting of 0.95. This is ideal for the measurement of food, non-metals (paper, ceramic, gypsum, wood, paints and varnishes) and plastics.

11.3 Measuring range, distance

Depending on the distance of the measuring instrument from the measurement object, a specific measuring range is recorded.

12. Information on contact measurement

▶ Observe the minimum penetration depth for immersion/penetration probes:
10x probe diameter
- Avoid using in aggressive acids or alkalis.
