Review on Extech Digital Insulation Tester πŸ”Œ 380260: Advanced Auto-ranging Technology for Accurate Testing by Todd Calloway

Revainrating 1 out of 5

The other options work fine so far but the main one is not

I bought this tester and 4 months after the isolation test the function just stopped working. The rest of the options still work fine, but the main one doesn't. Very sad because it suddenly happened when I was using the tester in one of my projects.

Pros
  • Handsfree
Cons
  • Somewhat wrinkled
