Product-specific buyer note

Confirm the Standard DSO-TC3 package and seller warranty in writing; the official two-year term does not transfer to Toolworld. Its 500 kHz bandwidth and 10 MSa/s sampling are for low-frequency hobby diagnostics, not fast buses, RF or a bench-scope replacement. Independent reports praise the compact component tester but also note confusing navigation and compromises, so verify intended signal range before buying.

India regulatory note

Do not treat FNIRSI's 400 V headline as a trustworthy measurement-category rating: no credible CAT rating was established. Never connect this pocket instrument to live mains, distribution panels or other high-energy nodes. De-energise and discharge components before using the test socket, observe probe attenuation and ground-reference safety, and use a properly rated isolated instrument for hazardous circuits.
