1. Safety
1.1 Equipment Markings
1.2 Operational Safety
The Socket and See EPF PRO is designed to be used by skilled persons in
accordance with safe methods of work. If the EPF PRO is used in a manner not
specified by Socket and See, the protection provided by it may be impaired.
Inspect the EPF PRO before using. If any damage is visible such as cracks in the
casing the unit should not be used.
The intermittent beep and flashing blue LED indicate that the tester is
functioning correctly.
The unit will power off automatically after 3 minuets to preserve battery life.
Caution - refer to the instruction manual
Construction is double insulated
Product should be recycled as electronic waste
Conforms to EU standards
Measurement Category IV is applicable to test and measuring
circuits connected at the source of the building’s low-voltage MAINS
installation. This part of the installation is expected to have a
minimum of one level of over-current protective devices between
the transformer and connecting points of the measuring circuit.
Due to these high short-circuit currents (above 50kA) which can be
followed by a high energy level, measurements made within these
locations are extremely dangerous. Great precautions shall be made
to avoid any chance of a short circuit.
Examples of CAT IV are measurements on devices installed before
the main fuse or circuit breaker in the building installation.

During use, your hand must be behind the instrument safety barrier. Ensure the
instrument is gripped firmly
To maintain safety, check the correct operation of the EPF PRO, both before
and after use, with a true AC output proving unit such as the socket and See
SP400 or a known live source.
The EPF PRO has been designed to be used with PPE including insulated gloves,
if required.
Never attempt to use the instrument on any circuit where voltage exceeds
600VAC.
Do not change the batteries if the instrument is connected to a live circuit.
1.3 Limitations of Using the EPF PRO to Detect Hazardous
Voltages
The limitation of any single pole voltage testers is that a so called ‘ghost
voltage’ may indicate a voltage present greater than 50 volts.
Ghost voltages that appear to be greater than 50 volts may not be dangerous,
however to prove if the voltage indicated is a ghost or dangerous real voltage
a quality 2 pole tester (such as one from the Socket & See VIP range) should be
used to prove the indication obtained from the EPF PRO.
For further information on single pole voltage detection and ghost voltages
please refer to the technical document on the Socket & See website.

2. Description
The UK designed EPF PRO is a dual function hazardous voltage and live phase
finder which will detect whether voltages greater than 50VAC are present in
order to protect operatives from dangerous live circuits, direct contact or
leakage situations at electrical cabinets, street lighting columns and wooden,
concrete and metal poles carrying live overhead supplies.
Identification of live phase conductors
As the EPF PRO uses direct contact for measuring (using safest method known,
capacitive coupling). The identification of the live phase is more certain than
using non-contact voltage indicators or similar devices.
The EPF PRO is extremely safe to use as there is no need to operate touch pads
or any other direct contact method to operate the unit correctly.
● Meets international safety standard BS EN 61010-1:2010
● Voltage measurement range 50 – 600VAC
● Safe live phase detection
● Flashing red front section plus audible warning indicates greater than
50VAC is present
● Slow flashing blue LED with single beep monitors EPF PRO electronics
are working correctly
● EPF PRO is fully functional even if wearing full PPE
● Robust construction with IP54 water and dust ingress rating
● Probe tip conforms to HSE recommendations GS 38
3. Usage
3.1 Battery Installation and Status
The EPF PRO uses 2 x LR6 AA alkaline batteries - rotate the battery cover at the
base of the unit using a coin or similar, insert the batteries (negative terminal
first) and replace cover. After inserting batteries and before use test the unit for
correct operation.
To check battery status, with nothing connected switch the EPF PRO on. If the
blue LED flashes and the front section illuminates, the electronics are working
correctly and the batteries are good .If the front section red LED flashes the
batteries need replacing. Dispose of batteries as required by local regulations.

3.2 Operation
Important
The tip of the EPF PRO should be placed firmly in contact with the pole or metal
cabinet or exposed terminals/cables under test. Fault leakage voltage found
or live phase conductors above 50V will be indicated by the front section
flashing red and by an audible tone.
Slow flashing blue LED
with single beep monitors
EPF PRO electronics are
working correctly
Main on/off switch
Turn the unit on by pressing and briefly
holding this button. The blue LED above
the finger guard flashes slowly and is
accompanied by a single beep. This
indicates that the EPF PRO electronics
are working correctly. Should this not
happen the EPF PRO should not be used
