INTRODUCTION
Thank you for purchasing the HHM-NVC40 Audible/Visual
Non-contact Voltage Detector with Adjustable Sensitivity.
Detector with Please read this manual carefully and
thoroughly before using the product.
The HHM-NVC40 provides a safe (non-contact) way to check
whether an electric line or cable or AC outlet is “hot”
(energized). It does so by sensing from a short distance the
electromagnetic field created by AC voltage.
Even unloaded AC circuits generate electromagnetic fields.
Although these fields are extremely weak, their constantly
changing nature means that they generate some current.
A sensitive non-contact voltage detector can sense this
current via induction, in much the same way that a sensitive
radio receiver can sense weak radio waves.
Non-contact voltage (NCV) detectors, including the HHM-NCV40
cannot detect DC voltages, such as those found in automotive
electrical systems. Like other NCV units, the HHM-NCV40
cannot detect AC voltage through a wall or metal conduit.
