• Select NCV mode and move the tip of the clamp meter near voltage source.
Both an Audible and Visual alert will indicate voltage.
• Non-Contact Voltage Detection is used to detect power with sensor located
in the tip of the clamp head indicates positive response with both an Audible
and Visual alert.
• Do not use non-contact voltage detector to determine if there is current on
the wire. Detection operation could be affected by socket design, insulation
thickness, type or other factors.
• Voltage indicator light may also light when voltage is present on the meter’s
input jack or from an external interference such as motors, flashlights, etc.
