The Megger VF6 EX 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.
The product is EX rated for use on gas platforms and other
petrochemical environments.
The detector has both low voltage (12 V - 1000 V) and
medium voltage (100 V - 1000 V) ranges.
The VF6 EX has the added advantage of a bright-white LED
torch for use in poor light.
The Megger VF6 EX 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
Hazardous areas, gas platforms and petrochemical
installations
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
EX rated for use in explosive atmospheres /
petrochemical locations
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 VF6 EX 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 VF6 EX.
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.
Use only GP AAA / LR03 batteries; do not replace batteries
when an explosive atmosphere is present.
NOTE: The VF6 EX is unable to detect voltage on armoured
or sheathed cable, 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 VF6 EX 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 VF6 EX off: Momentarily press the
On/Off button. The VF6 EX will beep twice and vibrate
twice and the green LED will turn off.
3. Turning the Sounder off and Vibrating motor off:
Turn the VF6 EX on as described above. The VF6 EX 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 VF6 EX, (1) Make sure
the green LED is on, (2) Check VF6 EX on a known live
AC voltage that is within the defined detection range
of the VF6 EX.
5. Low Voltage Mode (12 to 1000V AC): Press and
hold the 12 V button. The green LED will change to
orange to indicate the VF6 EX is in the low voltage
mode. While pressing the 12 V button place the tip of
the VF6 EX 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 VF6 EX 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 to 1000V AC): Place
the tip of the VF6 EX near an AC voltage. If the VF6 EX
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 batteries are 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 twice, vibrate 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 below.
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.
