Tools and Hardware Reviews of Fluke 1AC-A1-II Volt-Alert AC Non-Contact Voltage TesterCustomer Review: Stay away Summary: 1 Stars
The Fluke 1AC-A1-II looks like a drop-resistant design. Some of the other brands of testers break if dropped a few times.
I thought the unit would beep, but it didn't. The package doesn't say anything about an audible warning, but various web sites say it does. Buried in the instructions is the secret button press to get it to beep. It's in the timing of the on/off button. If you want the beep, you have to remember the correct way to turn it on. Poor design in my opinion.
I turned it on and it flashes a red red light to let you know it's on. The same red LED glows steadily for a warning. In my opinon having the red power light also be the warning alert is unconventional and confusing. Most other testers have a green LED to let you know it's on, and a separate flashing red LED for the alert. Why Fluke did it this way is puzzling and deviates from industrial safety standards that dictate that red indications should ONLY be used for alarms or warnings.
Instead of a unique warble like the Greenlee units, the Fluke makes a steady annoying beep that sounds like an appliance timer. Not a well thought out design in my opinion.
The Fluke's response time appears to be slower than the Greenlee. You hold it near a wire or stick it in an outlet and it takes a second to respond. Probably because it's using the same LED for power-on and circuit detection so it takes time to switch modes. Poor design in my opinion.
My unit also gave several false negatives with operating modes not mentioned in the manual:
In some hot outlets the LED continued to flash and it beeped continuously at the same time. No word in the instructions what that means.
In some situations the LED continued to flash and it beeped intermittently at the same pace as the LED. No word in the manual about that mode either.
In some hot outlets taking your hand off the unit would make it falsely indicate the circuit was dead. Touch the unit and you get the continuous glow and beep, as you should. No word in the manual about that deadly situation. Kind of useless if you want to stick it in an outlet and see which breaker kills the circuit.
It was cheap enough so I probably won't return it, but I can never trust it and will definitely buy a different one very soon.
Safety Note to Homeowners: No tester like this or any that I know of will alert you to a shared neutral circuit. It is common to connect neutrals from different circuits in any given J-box. The advantage is the increased current carrying capacity and redundancy of the "networked" neutrals. The disadvantage is that you can shut a breaker off and still get zapped thru the neutral side of the circuit. I may buy an adjustable Greenlee GT-16 to see if it will detect this situation.
Description of Fluke 1AC-A1-II Volt-Alert AC Non-Contact Voltage TesterSimply touch the tip to a terminal strip, outlet or cord. When the tip glows red, and the unit beeps, you know there's voltage in the line. Electricians, maintenance, service, safety personnel can quickly test for energized circuits and defective grounds on the factory floor, in the shop. Continually tests its battery and its circuit integrity with a periodic double flash visual indication using Fluke Voltbeat technology. It comes with a two-year warranty. It detects line voltage from 90VAC - 600VAC (1AC-AI-II).
