2. Inhalt der Box
Überprüfen Sie nach dem Auspacken, ob alle Komponenten vorhanden sind:
- Testo 175 T3 temperature logger (2-channel, with external sensor connections for thermocouple type T and type K)
- Wandhalterung
- Sperren
- Batterien (3 x AAA)
- Kalibrierprotokoll
Notiz: External thermocouple probes and a USB cable for programming/reading are sold separately and are required for full functionality.
3. Einrichtung
- Einlegen der Batterie: The Testo 175 T3 uses 3 AAA batteries. These are included. Ensure correct polarity when inserting. The logger is designed to retain saved measurement data even if batteries are empty or replaced.
