Introduction
Congratulations on your purchase of Extech's Insulation Tester/Megohmmeter. The Model 380260
provides three test ranges plus continuity and AC/DC voltage measurement. A handy test lock feature
and a data hold function are also included. This professional meter, with proper care, will provide years
of reliable service.
Safety
1. Circuits under test must be de-energized and isolated before connections are made (except for
voltage measurements).
2. Circuit connections must not be touched during a test. Use extreme caution when working near
bare conductors and bus bars. Accidental contact with conductors could result in electrical
shock.
3. Use caution when working near voltages above 60VDC or 30VACrms.
4. After insulation tests, capacitors must be discharged.
5. Test leads (including alligator clips) must be in good working order, clean and without broken
or cracked insulation.
6. When servicing, use only specified replacement parts.
