4. Nastavení
4.1 Vybalení a kontrola
Upon receiving your ADS824A oscilloscope, carefully inspect the packaging for any signs of damage. Open the package and verify that all standard accessories are present:
- OWON ADS824A Digital Oscilloscope
- Napájecí adaptér
- USB kabel
- Passive Probes (4 units)
- Rychlý průvodce
- Kalibrační certifikát
Pokud některé položky chybí nebo jsou poškozené, ihned kontaktujte svého prodejce.
4.2 Zapnutí zařízení
