Voltage Detector 90-1000V AC

The Fluke 1AC-A1-II is a non-contact voltage detector designed for electrical professionals and technicians. It identifies alternating current from 90 to 1000 volts without direct conductor contact. Audible and visual alerts signal the presence of voltage instantly. The tool carries a CAT IV 1000V safety rating for high-energy environments.

Pre-Use Verification Steps

Confirm the tester functions on a known live source before each job using the continuous self-test feature. Ensure the AAA alkaline battery is installed and charged for reliable operation. Verify the work environment does not exceed the 1000V AC maximum rating. Remember this device detects AC voltage only and has no DC measurement capability.

Replaces Basic Test Lights

This detector upgrades from simple neon test lights or unrated probes by adding non-contact detection and a CAT IV 1000V rating. The jump is worth it when safety standards require verified overvoltage protection and audible confirmation in noisy settings. It is not suited for users needing DC voltage checks, precise measurements, or a built-in flashlight.

Questions about this item

Does the Fluke 1AC-A1-II come with the two AAA alkaline batteries it needs, or must they be bought separately?

The detector ships with two AAA alkaline batteries installed, so it is ready to use straight away.

Is the 90-1000 V AC range the only version available, or are there lower-voltage models to choose from?

This model covers 90 V to 1000 V AC; the supplier lists no other voltage-range versions for the 1AC-A1-II.

What does the CAT IV 1000 V rating mean when I am testing a live mains socket?

CAT IV 1000 V means the tip is rated for permanent connection at the service entrance, so it is safe for checking mains sockets and distribution panels.
