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.
