Caution - refer to the instruction manual.
Construction is double insulated.
Product should be recycled as electrical waste.
Conforms to EU standards.
Prohibited to use on Electrical Systems which use voltages above
550V.
Measurement Category IV is applicable to testing and measuring
circuits at the origin of the installations supply. They are utility
level checks. This part of the installation is expected to have a
minimum of one level of over-current protective device between
the transformer and connecting points of the measuring circuit.
This tester’s voltage rating for CAT IV location is 300V where the
voltage is Phase (line) to Earth.

1. Safety
1.1 Equipment Markings
1.2 Operational Safety
The RCD PRO is designed to be used by skilled persons in accordance with
safe methods of work. If the RCD PRO is used in a manner not specified by
Socket & See, the protection provided by it may be impaired.
Inspect the product before using. If any damage is visible; such as cracks in
the casing, damage to any accessories, leads or probes, the unit should not
be used.

3
Do not operate the RCD PRO with the battery cover off as this will
compromise the insulated safety barrier.
To maintain safety, ensure serviceability and to monitor accuracy of the
RCD PRO the tester should be checked on a checkbox such as the Socket &
See CB400 at regular intervals.
When connecting to mains, ensure the colour coding on the test leads and
terminals is adhered to.
Although fully protected against over voltage up to 440V, the tester should
only be used on 230V systems.
2. Description
The RCD PRO is a digital RCD tester that will test the most commonly
encountered RCD’s to current standards. This includes standard (AC) type,
selective (ACS) type and A type RCD’s.

2.2 Indication
The white display backlight will illuminate when switching on and during
testing. To preserve battery life the backlight will switch off after
approximately 4 seconds of inactivity. The unit will automatically power off
after approximately 3 minutes of inactivity. To switch the tester back on after
auto power off press any button. A fail condition will be indicated by a red
backlight and a warning tone.

3.1 Battery Installation
Unit requires 4 x AA batteries.
Ensure that all test leads are removed before installing batteries. Remove
the rubber over mould then the battery cover on the reverse of the unit.
Install the new batteries ensuring correct polarity as indicated. After
installing batteries and before use ensure the battery cover and rubber
over mould are correctly fitted, switch on the unit and check for correct
operation.
Dispose of used batteries as per the local authorities guidelines.
3.2 Operation
30mA Auto Test
The 30mA auto test is available for A and AC type RCD. Select the required
30mA auto test on the rotary dial. The tester will monitor the mains for
correct polarity and voltage. If parameters are correct the Volts Present
LED will illuminate green and a test can the carried out. On pressing the
test button. The auto test will begin. X½ , x1 and x5 tests will
automatically be carried out at 0º and 180º. The results can be seen by
using the recall button to toggle through results.
RCD Manual Testing
Select the required RCD type on the rotary dial. Then use the multiplier
button to select the required test current. If the mains polarity and
voltage is correct the volts present LED will illuminate green and a test can
be carried out by pushing the test button. The first test will always be
done at 0°. The tester will then automatically cycle to 180° ready for the
next test.
Ramp Test
Rather than applying a set test current, this gradually increases the level
of additional leakage to identify at what current the RCD trips. Select the
required RCD type on the rotary dial. Then use the multiplier button to
select the ramp feature. If the mains polarity and voltage is correct the

6
volts present LED will illuminate green and a test can be carried out by
pushing the test button. The tester will display the leakage current at
which the RCD tripped along with a pass or fail indication.
Hands Free
The Hands Free function can be used with any RCD test. Select the
required RCD type on the rotary dial. Press the Hands Free button,
HANDSFREE will be displayed on the screen. Once the tester is connected,
correct voltage and polarity is confirmed a RCD test will be conducted
without TEST being pressed.
Polarity Test Pad
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 testers will test and show that everything is
correct despite this very dangerous wiring condition. Although extremely
rare, this dangerous condition can exist, so if your test shows this fault do
not proceed.
Touch the touchpad area next to the test button. There should be no
change in the indication given. If the Voltage/Polarity LED flashes Red and
a warning tone is emitted when the touchpad is touched a potentially
dangerous polarity reversal exists. Do not proceed. If in any doubt advise
the customer to contact the electricity supply company immediately.
4. Maintenance and Service
If required, clean with a soft damp cloth and mild detergent. Do not use
abrasives or solvents.
With the exception of the batteries there are no user serviceable parts.
Contact Socket & See for parts and technical assistance.
