Product Information
Full details
The Fluke 1AC-II is an essential tool for electricians and DIY homeowners who need a quick, safe method to verify the presence of AC voltage without stripping wires or making direct contact. Its primary benefit is the ability to detect current through insulation, ensuring safety during electrical inspections or repairs, though users should be aware that it cannot determine the exact voltage level or distinguish between live and neutral wires.

FAQs
Does this detector work on DC voltage?
No, the Fluke 1AC-II is specifically designed for AC voltage only (90 V to 1000 V).
Can this tell me if a wire is live or neutral?
No, it detects the presence of an electromagnetic field created by AC voltage. It cannot distinguish between hot and neutral wires.
How do I know the battery is working?
The device features a continuous self-test function. If the device is not functioning correctly, it will typically not pass this internal check, providing a warning that it is not ready for use.
Can it detect voltage through metal conduit?
It may have difficulty detecting voltage through grounded metal conduit because the metal acts as a shield against the electromagnetic field.
Does it have a silent mode?
Yes, the device supports an audible or silent mode for use in different environments.
Troubleshooting
The tip does not glow or beep when placed near a known live source.
Check the battery installation. Replace the AAA batteries with fresh ones to ensure the continuous self-test circuit has sufficient power.
Device emits a constant signal even when away from voltage.
Static electricity can sometimes trigger the sensor. Touch the tip to a grounded surface to discharge static and try the measurement again.

- Audible and visual confirmation
- Pocket-sized for portability
Cons
- Does not measure specific voltage levels
- Cannot differentiate between neutral and hot wires
- Requires AAA batteries for operation
- Limited to AC voltage detection only
Setup, Compatibility & Care
To begin using the Fluke 1AC-II, install two AAA batteries by unscrewing the battery cap at the end of the unit. Ensure correct polarity as marked. Compatibility is broad, as it detects AC voltage in a range of 90 V to 1000 V, covering most standard household and commercial applications. For care, avoid dropping the unit on hard surfaces to protect the internal sensors. Keep the tip clean and dry; if the exterior becomes soiled, wipe it down with a slightly damp, lint-free cloth. Do not use chemical solvents for cleaning, as these may damage the plastic casing.
