The device automatically powers on when the penetration probe is unfolded. Ensure the display illuminates upon unfolding.
4. Operating Instructions
4.1 Infrared (IR) Measurement (Non-Contact)
For quick surface temperature readings, use the infrared sensor. This is ideal for checking temperatures of packaged goods or surfaces without direct contact.
- Ensure the penetration probe is folded in.
- Point the front of the thermometer towards the surface to be measured.
- Press the "ON" button to activate the infrared measurement and laser pointer. The laser dots indicate the measurement area.
- Verenga tembiricha inoratidzwa paLCD skrini.

4.2 Penetration Probe Measurement (Contact)
For accurate core temperature readings of semi-solid or liquid substances, use the foldable penetration probe.
- Unfold the penetration probe. The device will automatically power on.
- Insert the probe into the substance to be measured, ensuring the tip is fully immersed to the desired depth.
- Wait for the reading to stabilize on the display. The device has a fast reaction time (t99 = 10 seconds in moving liquid).

4.3 Hold and Min/Max Functions
- BATA: Press the "HOLD" button to freeze the current temperature reading on the display. Press again to release.
- MIN / MAX: While in measurement mode, press the "MIN/MAX" button to cycle through the minimum and maximum temperatures recorded during the current measurement session.
4.4 Simba Kudzima
To turn off the device, fold the penetration probe back into its housing. The device will automatically power down.
5. Kuchengeta
5.1 Kuchenesa
The Testo 104-IR is waterproof (IP65 rated), allowing for easy cleaning under running water or with a damp cloth. Ensure the probe is thoroughly cleaned and disinfected after each use, especially when used with food products.
