Caution
We strongly advise reading and understanding this guide
before the instrument is used. In particular note the safety
issues that follow:-
l Although fully protected up to 600V AC this tester is for
use on 230V AC circuits only.
l Always check the tester on a known correctly wired live
socket outlet before and after use.
l Before use - check your tester for any damage to
the plug, lead and cabinet.

At Socket & See our Engineers constantly look for improvement.
If there is any aspect of your Socket & See tester you would like
to comment on please visit our website at
www.socketandsee.co.uk
with any suggestions.
We promise all communications will be acknowledged.
We value YOUR opinion.
Important calibration/check box note
l Because of the Super Smart Loop Test System the test is
immune to sudden value changes (such as voltage spikes).
l As a result when changing calibration or check box loop
values the unit must be switched off between changes.

Operation overview
Your Socket & See tester has a special polarity test function.
It is a little known fact that a system can be reverse wired with Live (Phase) to
earth/neutral and earth/neutral to Live (Phase) The sockets will all work and
conventional loop testers will show and test that everything is correct despite
this very dangerous wiring condition.
Although extremely rare, this miswire condition can exist so if your test shows
this fault do not proceed - if in any doubt advise your customer to contact their
supply company immediately.

PDL 310
Operation overview continued
The PDL 310 is a multifunction tester testing for no trip loop, no-trip PFC (Prospective
Fault Current), mains voltage (L-N), correct socket wiring, and polarity.
Correct socket wiring and correct polarity
At the Socket Test stage the PDL 310 also accurately measures and displays the mains
voltage in the LCD (Liquid Crystal Display).
A reminder of the correct voltage range 207-253V AC (Harmonised Standard BS 7697
HD 42S1) is given above the display.
If the Voltage Range is outside of this standard, stop testing - your customer should notify
their electricity supply company of the problem.
If the three socket LED’s are GREEN (correct) and the correct voltage is displayed you
can proceed to Polarity Test.
The reasons for Polarity Test are covered in detail on the previous page of this User Guide.
To carry out the test apply firm (thumb) pressure to the Polarity Test Pad, note this pad
does not depress. The three Socket Test LED’s should remain GREEN - everything is
correctly wired including Polarity (live and earth/neutral are in the right place).
If the LED’s change to RED when you operate the Touch Pad - it is possible a very
dangerous condition is present and the relevant electricity supply company should be
informed immediately of this indication.
If everything in this section is a good test result you can proceed to the next sequence
of testing (see page 7).

Plug the tester in and switch on the mains supply.
1. Power ON/OFF - Pressing and releasing this button turns the
PDL 310
on -
holding down for longer than two seconds turns the unit off (plus intelligent
Auto Power Off is incorporated).
2. All three LEDs GREEN = CORRECT wiring status, any other indication
(see back cover) - DO NOT PROCEED -investigation is required.
3. Check mains voltage is correct 207-253VAC
Important note:
All tests are inhibited until the mains voltage appears in the display
4. Polarity Test - this important test is discussed in full on pages three and
four of this manual, please read.
5/6. The push to test switch must be operated to initiate test (except if this button
is held down for approx two seconds HANDSFREE testing is selected which is
very useful for testing at DB’s (Distribution Boards), luminaires or similar
connecting strips.
Your tester defaults to no-trip loop testing when you first switch on -
button five re-selects no-trip loop test (and retests) if you have selected
other functions.
7. Having carried out a (no-trip) loop test - pressing this button calculates the PFC
(Prospective Fault Current) by dividing the measured loop result into the
measured L-N voltage.

Socket Test Technology
The PDL 310 uses our well proven Socket Testing patented technology to
indicate the socket is correctly wired.
Plugging the unit in and switching on mains supply automatically initiates the
socket test sequence.
If the socket is correctly wired the LED’s will be GREEN on this check.
If the socket is incorrectly wired one or more LED’s will go to FLASHING RED to
indicate there is a a socket miss-wire or other fault.
If flashing red (or orange) occurs using the touch pad at this stage, this should
show where the socket wiring problem is – as per the example below.
A unique feature of your tester is the ability to display by the position of the red
LED(s) where the problem is, EARTH, LIVE (Phase) or NEUTRAL.
A full list of wiring faults is shown on the back cover of this User Guide.
This is an example of ‘Fault Locate’ showing Live (Phase), neutral reverse.
