Who should be testing socket outlets?

Basically anyone who wants to know the mains socket 
about to be used is correctly wired and safe to plug into.
In particular those with a responsibility of care for their 
own homes, employees and the public.

 

Home owners

 

Land lords

 

Local authorities

 

Police forces

 

Hospitals, including home visits

 

Schools and colleges

 

Sports facilities

 

Military housing and education

 

IT managers

 

Heads of department

 

Health and Safety officers

Caution

Before use check the socket tester's case and pins for 
any signs of damage.
Do not use if the case is broken or damaged. To check 
the correct functioning of the socket tester, plug it into 
a known correctly-wired live 13A socket.
To clean the tester use only a soft dry cloth.
This unit is maintenance free and contains no user 
serviceable components. In the unlikely event that this 
unit malfunctions, it should be withdrawn from service 
and returned to Kewtech. 
This tester must not be used in a manner not specified 
by Kewtech.

Good work practice

Use of a Socket Tester will be seen to show a 
responsible attitude to electrical safety, plus the very 
reasonable price of Kewtech testers means they place a 
cost effective solution in the hands of many more users 
at the front end of responsibility and care.

What a Kewtech tester WILL  

tell you

The Loopcheck 107 is unique in that it is the only 
socket tester that carries out a loop test at mains 
frequency to check the actual condition of the wiring.

Particular emphasis is placed on detecting very 
dangerous wiring conditions such as reversed line 
(live) earth connections, disconnected wires and high 
earth values.

What a Kewtech tester will NOT 
tell you

Kewtech socket testers are for simple first line 
diagnosis for use by those with and without electrical 
skills. If a problem at the socket is shown it should 
immediately be investigated by a suitably qualified 
electrician or contractor recognised by organisations 
such as:
 

NAPIT (www.napit.org.uk)

 

NICEIC (www.niceic.com)

 

ECA (www.eca.co.uk)

 

ECA of Scotland (www.select.org.uk)

 

STROMA (www.stroma.com)

Specifications

Socket wiring check
Three green LEDs and a continuous tone indicate that the 
socket is correctly wired. Earth, Line (Live) and neutral 
are all in the correct position. Any other indication, such 
as open circuit or swapped connections, is shown by 
an orange or red LED accompanied by a warble tone. 
The socket is incorrectly wired and all further tests are 
inhibited.
Note:  Like all socket (and other similar) testers a neutral 
– earth swap cannot be detected unless the distribution 
board is fitted with an RCD in which case the RCD will trip.
Socket condition check
This is carried out by injecting a loop impedance test 
current between line (live) and neutral and also between 
neutral and earth. If during the pre-test there is an 
indication the earthed metal work could raise to touch 
voltage of greater than 25V the test is inhibited.

Mains Polarity test
This is a capacitively coupled pad. The user is the earth 
reference point for true earth.
This test is used to indicate that there is not a line (live) 
neutral swap of the mains supply at the supply entry point 
to the premises.

RCD test (30mA RCD only)
Operation of the test switch injects a test current of 
30mA Line (Live) to earth to provide an operational check 
for the RCD. The test current is restricted to 300ms. 

The result is shown by one of three LEDs.

Rating 230V.  Input current: <18mA (L–E <7mA)

Frequency: 50Hz.

Suitable for use in environmental conditions:

Temperature 0–40˚C 

Humidity: <95% non-condensing

This tester is not intended for continuous use – do not 
leave connected in a socket for longer than 2 minutes.
