GFCI Outlet TesterThis transmitter can be used as a standalone GFCI outlet tester, testing the tripping response time of the GFCI within seconds to determine if the GFCI is functioning correctly. The wiring status is clearly displayed via prominent red and green LED indicators, accurately diagnosing six common line faults.
Non-Contact Voltage DetectionThe receiver features built-in non-contact voltage detection (NCV) functionality. Its core principle is to sense the electric field generated around AC power lines, providing a rapid warning of a nearby live conductor through both audible and visual alarms without any physical contact. This function allows users to perform a quick and safe "pre-scan" before any electrical operation, establishing the first line of defense for electrical safety.
Package List1 transmitter (GFCI outlet tester), 1 receiver, 2 AA batteries for the receiver, 1 carrying case, 1 user manual.
