5. Auto power off
The detector will auto power off when it is not used for 5 minutes.
WARNING
Do not mix old and new
batteries. Do not mix alkaline,
standard (carbon-zinc), or
rechargeable (ni-cad, ni-mh,
etc) batteries.
3. AC voltage detection
Place the sensor head near the test object or the power socket
with AC voltage. When AC voltage is detected, the red LED in the
tip and buzzer will be on.
In vibration mode, when strong signals are detected, there will also
be vibration alarm (KN 8065-E only).
Note: Please unplug other electrical devices on the socket
before detection.
4. Detection range selection
a) When the detector is on, the default mode is high voltage mode,
with detection range of 90-1000V. The red indicator light on the
panel will light up.
b) Short press the power button once. The red indicator light will
switch to green, and the device will switch to low voltage mode,
with range of 24-1000V. In low voltage mode, the detector is
more sensitive to electrical interference/noise. Please only use
low voltage mode during weak electrical field environment.
(KN 8065-E only)
Note: In the magnetic field detection mode, voltage cannot be
detected at the same time.
6. Turning off the detector manually
Short press the power button to turn off the detector (KN 8065-S
only). Long press the power button for 2 seconds to turn off the
detector (KN 8065-S only).
8. Low battery indication
When the battery voltage is lower than 2.4V, the detector will
automatically shut down.
Battery Replacement
KN 8065-S:
1. Hold the detector with one hand,
use your thumb of the other hand
to press down on the battery
compartment latch, and pull
the end of the detector.
2. Pull out the end of the detector
along the direction shown at
right pictures and
replace the batteries.
KN 8065-E:
1. Unscrew the battery cap
counterclockwise as shown at
right picture, and then replace
the batteries according to the
polarity indication.
2. Tighten the battery cap
clockwise and the buzzer
will beep twice to indicate
the completion of
the replacement.

10. When using the detector, please only hold up to the line before
the translucent sensing part and not over.
11. Comply with local and national safety regulations and equirements.
12. The detector will not detect any voltage if:
• The wire is shielded
• The operator is not connected with the ground or isolated from
an effective ground
• The voltage is DC
13. The detector may not detect any voltage if:
• The operator does not hold the detector
• The operator is wearing gloves
• The wire under test is partially buried or in a grounded metal conduit
• The magnetic field generated by the voltage source is blocked,
suppressed or interfered with
• The frequency of the voltage being detected is not a perfect
sine wave and may be distorted by harmonics
• The detector is used outside of the operating specifications

Operating Instructions
1. Turning on the detector
Short press the power button. The buzzer will beep twice and
the red indicator light on the panel will light up, indicating that
the detector is on and ready for use. The default AC voltage
detection range is 90-1000V.
KN 8065-E only:
Long press (>1.5s) the power button. The detector will be on and
vibrate. The vibration alarm will also occur when a strong signal is
detected (only acousto-optic alarm for weak signals). To turn off
the vibration, power off the detector and then restart it by short
pressing the power button.
2. Turning on/off the flashlight
Flashlight on/off: Short press the flashlight button to turn on/off
the flashlight.
The flashlight will automatically turn off when the detector is not
used for 5 minutes.
