2. Saugos informacija
Always adhere to the following safety precautions to prevent personal injury or damage to the devices.
- Bendra sauga: Do not operate the devices if they appear damaged or if the casing is open. Ensure your hands are dry before handling electrical components.
- Multimetro sauga:
- Netaikyti ttage or current that exceeds the maximum rated values specified in the specifications section.
- Prieš keisdami funkcijas, visada atjunkite bandymo laidus nuo grandinės.
- Būkite atsargūs dirbdami su voltagesant didesnei nei 30 V AC RMS, 42 V pikinei vertei arba 60 V DC įtampai. Šie įtampų lygiaitagtai kelia šoko pavojų.
- Prieš atlikdami matavimus, įsitikinkite, kad pasirinkta tinkama funkcija ir diapazonas.
- Tachometer Safety:
- Do not stare directly into the laser beam. Avoid directing the laser at people or animals.
- Use the device only as intended for RPM measurement.
- Ensure the measurement area is clear of obstructions and moving parts are safely guarded.
