The Megger VF5 Voltage Detector is intended to check for
the presence of AC voltage, indicated by a bright red LED
situated within the white nylon tip and an audible sounder
plus vibration alert. A small white LED work light is also
mounted in the tip.
The detector has both low voltage (12 V - 1000 V) and
medium voltage (100 V - 1000 V) ranges.
The VF5 has the added advantage of a bright-white LED
torch for use in poor light.
The Megger VF5 is useful for identifying live conductors,
finding a break in a wire, verifying a blown fuse while in
circuit, and detecting AC voltage at:
Socket outlets
Switches
Circuit breakers
Fuses
Wires and cables
Luminaires
Features
Non-contact detection of AC voltage
12 V ~ 1000 V AC and 100 V ~ 1000 V AC 50 Hz / 60
Hz CAT IV 1000 V
Visual, audible and vibration warning of low and
medium voltages
Durable rubber over-moulded body
Built-in bright-white LED torch
Low power consumption
Convenient pocket-size
Safety Warnings
Read, understand and follow Safety Warnings and
Operating Instructions in the manual before using this
product.
The detector’s safety features may not protect the
user if not used in accordance with the manufacturer’s
instructions.
Check on a known live source within the rated AC voltage
range of the detector before use to ensure it is in working
order.
Insulation type and thickness, distance from the voltage
source, shielded wires, and other factors may affect reliable
operation.
The VF5 may help in the indication of live AC circuits only
and must not be used as verification of a de-energised
circuit. This is not a Safety Test Lamp.
Do not use if the detector appears damaged or if it is not
operating property. If in doubt, replace the product.
Do not use on voltages that are higher than as marked on
the VF5.
Use caution with voltages above 30 V AC as a shock
hazard may exist.
Comply with all applicable safety codes. Use approved
personal protective equipment when working near live
electrical circuits -particularly with regard to arc-flash
potential.
Do not operate detector if Low Battery warning occurs.
Replace batteries immediately.
NOTE: The VF5 is unable to detect voltage on armoured or
sheathed cable, or on cable in conduit, behind panels or in
metallic enclosures.

Detector Description
1. Screw on battery cover
2. Torch
3. Torch button
4. 12 V button
5. On/Off button
6. LED indicators
7. Detector tip
8. Work light
Operation
1. Turning the VF5 on: Momentarily press the detector
On/Off button. The detector will beep once, vibrate
once and the green LED will illuminate to indicate that
the detector is on and ready for use.
2. Turning the VF5 off: Momentarily press the On/Off
button. The VF5 will beep twice, vibrate twice and the
green LED will turn off.
3. Turning the Sounder and Vibrating motor off: Turn the
VF5 on as described above. The VF5 will now operate
with both the sounder and the vibrating motor. To
turn the sounder and vibrating motor off, press and
hold the On/Off button until the green LED flashes
once. To turn the sounder and vibrating motor back on
press and hold the On/Off button until the green LED
flashes, the sounder beeps and the unit vibrates.
4. Verify Operation: Before using VF5, (1) Make sure the
green LED is on, (2) Check VF5 on a known live AC
voltage that is within the defined detection range of
the VF5.
5. Low Voltage Mode (12 V to 1000 V AC): Press and
hold the 12 V button. The green LED will change to
orange to indicate the VF5 is in the low voltage mode.
While pressing the 12 V button place the tip of the
VF5 near an AC voltage. When AC voltage is detected
the LED will turn red and flash, the sounder will beep
and the detector will vibrate. The flash, beeping and
vibration rate will increase as the VF5 gets closer to the
voltage source. If the VF5 detects a medium voltage
(100 V – 1000 V) it will automatically change over to
the medium voltage mode, the red LED will change to
a steady glow, the sounder will beep rapidly and the
detector will vibrate constantly.
6. Medium Voltage Mode (100 V to 1000 V AC): Place
the tip of the VF5 near an AC voltage. If the VF5
detects voltage within the defined detection range the
green LED will turn off, the red LED will turn on, the
sounder will beep rapidly and the detector will vibrate
constantly.
NOTE: The detector cannot determine the actual voltage.
The voltage level where the detector switches from the
low to medium voltage mode is affected by insulation type
and thickness, distance from the voltage source, and other
factors.
7. Low Battery Indication: Replace the batteries if the
green LED does not turn on. When the detector is
on and the battery voltage is too low for reliable
operation, the sounder will beep three times and the
green LED will turn off indicating the detector is not
operational. Replace the batteries to restore operation.
8. Auto Power Off: To conserve battery life, the detector
will automatically turn off after approximately 5
minutes of inactivity. When powering down the
detector will beep, vibrate twice twice and the green
LED will turn off.
9. Torch: Momentarily press the torch button to turn the
torch on or off. To conserve battery life, the torch will
automatically turn off after approximately 5 minutes.
NOTE: If the battery voltage is too low to operate the torch
the detector will indicate this condition by beeping three
times and the torch will turn off. The voltage detector has
its own low battery threshold and may remain operational.
Refer to Verify Operation (Step 4) in this guide before using
detector.

Battery replacement
1. Carefully unscrew battery cap at the rear (torch end) of
the detector.
2. Replace batteries with 2 x AAA 1.5V batteries. Observe
polarity.
3. Carefully align cap with detector as shown above.
4. Screw cover onto the detector until it feels tight; do
not use excessive force.
5. Verify operation by using the detector on a known live
AC voltage within the defined detection range of the
detector.
Note: When batteries are loaded for the first time,
please remove the white rectangular security strip before
installing.
When replacing the batteries, be sure to secure the cap
firmly to maintain IP67 water and dust protection. A loose
or over tightened battery cap may compromise water and
dust protection.
