Product overview: Fluke T+ Electrical Tester

How to use the T+ Electrical Tester

The T+ Electrical tester offer three ways to know if AC/DC voltage is present. It lights up, makes a sound, and vibrates for added user protection. With these indicators, the user will be alerted to the presence of voltage even in dark, or noisy environments. The audible indicator can also be easily switched off - with the push of a button.

Part of the safety designed into the T+ Electrical Tester is that is can still detect live voltage even when the batteries are dead. It also holds a safety rating:

CAT IV 600 V, CAT III 1000 V

Fully compliant with NFPA 70E

GFCI Trip testing

The T+ tester has a GFCI Trip for testing GFCI circuits on outlets. A built-in flashlight also lets the user highlight the test point being measured for easier visibility.

The back of the tester is also designed with convenient test lead storage. And all of that is backed by a 2-year warranty.
