General Inspection
We suggest checking your new UT4000 oscilloscope in the following steps.
1. Check the unit for possible shipping damages
If the package carton or foam plastic protective lining is seriously damaged, do not
discard until you have carried out an electrical and mechanical check and found the
product and accessories performing satisfactorily.
2. Check the accessories
A checklist of accessories that come with your UT4000 oscilloscope is provided in the
section “UT4000 Accessories” of this user manual. Please check for any missing items
against this list.
If any item is missing or damaged, please contact your UNI-T dealer or our local office.
3. Thorough inspection of the entire unit
If the exterior of the unit is damaged, or it is not operating normally, or it fails to pass the
performance test, please contact your UNI-T dealer or our local office.
