Safety Information
Compass was designed with safety in mind, but no design
can completely prevent incorrect use. It should be used by
trained and qualified personnel only. Electrical circuits can
be dangerous and lethal so always use caution and strictly
adhere to proper safety practices. Use proper high voltage
procedures for testing and grounding. Wearing personal
protective equipment is a necessary safety precaution when
working around high voltage equipment.
• Read the User Manual carefully and completely before
using Compass.
• Compass should never be placed in direct contact with a
live conductor or the wearer’s body.
• Do not rely on Compass as your sole source of high
voltage detection. Compass must never be in physical contact with a conductor. This is a proximity detector,
not a device which works by contact.
• Prior to using Compass in the field, make sure to test and verify that sensitivity settings match employees
workspace needs.
• Always check that Compass is working before using it in the field.
• Risk of electrocution is intrinsic in and around high voltage.
Overview
Compass is a non-contact high voltage detector that alerts users when they approach an electrified source.
Its advanced notification system is designed to warn the user of the presence of voltage and current within a
proximate area. Compass’ internal sensors were designed to detect both electrical (V/m) and magnetic (T) fields.
Radiated electric and magnetic fields increase with higher distribution voltages and decrease with distance and/or
shielding. Compass is to be worn only on the underside brim of a standard hard hat and positioned to be within
the peripheral view of the wearer. Once an energized source is detected, the user is notified first by LED lighting of
the approximate distance and then is followed by indicating the direction of the source. These warnings are shown
to the wearer by the line of LED lights located within the peripheral view of the wearer.
