Red
 Warning – For non-contact voltage sensing, do not
touch Hazardous Live conductors with the red or black
test-probe.
• For non-contact voltage sense, place the top of
the instrument body or the red test-probe near
the conductor.
• The buzzer will sound and the number of dashes
shown on the LCD will indicate the relative electric field
strength. If there is no indication, a voltage may still be
present.
