1AC-II/1LAC-II VoltAlert
The pocket-sized voltage detector
The next generation VoltAlert™ ac voltage testers from
Fluke are easy to use—just 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, mainte-
nance, service, safety personnel, and homeowners can
quickly test for energized circuits and defective grounds on
the factory floor, in the shop, or at home.
•
The 1AC-II continually tests its battery and its circuit integrity
with a periodic double flash visual indication using Fluke
Voltbeat™ technology.
•
The VoltAlert™ Tester (1AC-II and 1LAC-II) is a Category IV —1000 V
overvoltage rated product for added user protection, the highest
rated of its kind.
•
Voltage detection of 90 V to 1000 V ac or 200 V to 1000 V ac
depending on model, as well as a 24 V to 1000 V ac control
circuit model.
•
It is rugged, reliable, and has a two-year warranty.

Specifications
Operating principle
Senses the steady state elec-
trostatic field produced by ac
voltage through insulation
without requiring contact to the
bare conductor. A red glow at
the tip and a beeping noise (if
not switched OFF) indicates the
presence of voltage.
Note: Does not respond to random
electrostatic discharge.
