• 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.

On Voltage

Approx. 25V AC

Disconnect test lead probes from voltage source and meter.

• Press Select button to change between Fahrenheit and Celsius
