2. Introduction
Thank you for selecting the FLIR VP40_VP42 Non-Contact Voltage Detector. Proper use
and care of this meter will provide many years of reliable service.
The VP40_VP42 detects the presence of AC voltage at electrical outlets, junction strips,
electrical circuits, and other devices without having to contact the device physically. The
VP40 has a minimum excitation voltage of 90V AC; The VP42 has a minimum excitation
voltage of 190V AC. Both models have a high sensitivity mode allowing detection down
to 24V AC. Vibrating and visual cues alert the user when AC voltage is present.
The bright tip lights, near the sensor tip, permit operation in dimly lit areas. Note that
when you switch ON the larger Flashlight, the detector will not operate.
This device is shipped fully tested and calibrated and, with proper use, will provide years
of reliable service.
