General Description
The Wet Roof Pro’ leak detector compliments the existing range of
Buckleys Dry Roof Pro’ test instrument to provide a complete roof test
system for all occasions. The Wet Roof Pro’ has been designed as an
aid to identifying the source of leaks on roofing technologies that
incorporate dielectric membrane overlays. With large easy to read
graphics displays and user-friendly icons enabling fast accurate roof
surveys to be undertaken.
The Wet Roof Pro’ leak detector kit comprises two main elements:
A ‘generator unit’ which provides stabilised low frequency pulses. The
negative output is applied to a trace wire bordering the test area and
the positive output is connected to a suitable earthed point of the
building’s substrate. Within the test area - if moisture has penetrated
the roofing membrane - electrical current will flow from the trace wire
towards the source of the leak; via the moisture on the roof.
By conducting a systematic survey of the roof test area the operator is
guided by the detector unit toward the origin of the leak. The leak origin
is the fault or point of failure within the roof membrane where moisture
has penetrated.
The hand-held survey poles connect to the detector unit allowing for
precise location of the leak origin. Both generator and detector units
are powered by operator replaceable batteries, either standard
disposable alkaline batteries or rechargeable cells which can be
charged using the battery charger supplied. The battery charger also
has an in-car adaptor to allow charging of batteries whilst travelling
between sites.
Attention! The charger is only suitable for recharging nickel-
cadmium (NiCd) or nickel-metal hydride (NiMH) cells. Non
rechargeable batteries or other types could cause an
explosion. Do not attempt to charge zinc/alkaline batteries
or other types of non-rechargeable, primary batteries.

To switch the generator unit off press and hold the button for longer
than two seconds.
Fig. 2 (below), details the generator graphics display. The pulse
frequency and pulse duration can be stepped through three separate
settings, these are 0.25Hz at 30% duration, 0.50Hz at 30% duration and
0.50Hz at 50% duration. Each pulse function can either be with or without
the sounder active, giving six possible combinations.
NOTE: Hz is the international symbol for frequency. A 0.5Hz pulse
equals 2 seconds, while 30% refers to an ‘ON’ time (voltage present at
the output sockets). Therefore, 30% of 2 seconds gives an ‘ON’ time of
0.6 seconds and 1.4 seconds ‘OFF’. The sounder will alarm during the
‘ON’ period if it has been selected.

The button (item D –fig.1) sets the output voltage pulsing at the
frequency and duration selected. Whenever the output voltage is
present (on) the pulse function icon (item B –fig. 2) is highlighted,
changing state from plan square to radiating square.

Please ensure that the input plug ‘clicks’ into the power supply to ensure the
unit is safe to use. Connect the power supply to the charger. Finally, connect
the power supply to the mains (100-240V AC 50-60Hz).
To change the input plug, push the locking lug below the plug (e.g. using a
pen) until the plug can be moved slightly upwards. Then remove the plug.
Using the charger in a vehicle
Connect the DC charging cable to the charger. Connect the DC charging
cable to the 12V DC car socket of your vehicle (do not use in 24V DC truck
sockets). Please make sure that the power of the socket is switched on. Some
cars require the ignition to be switched on.
The charger is now ready for use. You can insert one 9V E-block and up to 4
AA/AAA/C/0 (in any combination) NiMH or NiCd rechargeable batteries. You
can also connect an USB cable using the USB charging socket to charge
other devices such as, smartphones or MP3 players. Insert all batteries with
correct polarity, corresponding to the symbols in the charging slot.
Charging of round cells
The charger has 3 function buttons; ‘CURRENT’, ‘DISPLAY’ and ‘MODE’ (see ‘A’
in illustration on page 16). Use these buttons to select the following settings:
•MODE button
Push the ‘MODE’button within 8 seconds of inserting 1-4 rechargeable
batteries, to access one of the following charging programs:
A CHARGE: Charges battery. After charging is complete, charger will
automatically switch to trickle charging (trickle charge will commence
after all modes)
B DISCHARGE: Discharges battery before charging to minimize the
‘memory effect’of batteries
C REFRESH: ‘DISCHARGE REFRESH’ or ‘CHARGE REFRESH’status is shown on
the LCD display when charger cycles between discharging and
charging. This process will refresh old batteries and bring totem back to
the maximum capacity. Refresh will be repeated (max. 10x) until the
charger can no longer register a rise in capacity.
D TEST: Fully charges battery. LCD display shows ‘CHARGE TEST’Discharges
battery and measures capacity. The LCD shows ‘DISCHARGE TEST’.
Recharges battery, ready for use. LCD shows ‘CHARGE TEST’.

•CURRENT button
Push the ‘CURRENT’button within 8 seconds of selecting a charging
program or after inserting batteries to select the charging current for the
program ‘CHARGE’or ‘TEST’. Alternatively, choose the discharging current
for the program ‘DISCHARGE’or ‘REFRESH’.
•DISPLAY button
Push the ‘DISPLAY’button whilst charging or discharging to display the
charging/discharging current (mA), the voltage of the rechargeable
battery (V), the charging/discharging capacity (mAh or Ah) or the
remaining charging/discharging time (hh:mm).
Once the settings have
been selected, the
charger automatically
starts with the selected
parameters after 8
seconds. If no settings
are chosen, the LCD
display will flash after
inserting rechargeable
batteries. First the
voltage of the
rechargeable batteries
as well as the pre-set
charging program
‘CHARGE’is shown.
Next, the pre-set
charging current of 600mA is shown. After 8 seconds the charging process
starts automatically using the pre-set parameters.
By using the 4 charging slot buttons (see ‘B’ in illustration above) you can
make individual settings for each rechargeable battery. To change a function
for a single rechargeable battery, press the corresponding button below the
charging slot for the chosen battery. The display will flash for this battery and
you can now change settings, as described above, for the single charging
slot using the function buttons ‘MODE’and/or ‘CURRENT’.

If only one or two rechargeable batteries are inserted into the charger using
the two outer charging slots, in the mode ‘CHARGE’ and ‘TEST’the charging
current can be increased up to 1500mA or 1800mA with the ‘CURRENT’
button. In this case the inner charging slots are disabled and cannot be used.
When charging three or four rechargeable batteries at the same time, the
charging current can be set to 400mA, 600mA or 800mA. Using the programs
‘DISCHARGE’ and ‘REFRESH’discharging currents of 200mA, 300mA or 400mA
can be selected. The charging current is generally twice as high as the
chosen discharging current.
A few minutes before the rechargeable batteries are completely charged,
the charger reduces the charge current to ca. 200mA, regardless of the
previously selected charge current. This gentle full-charging extends the
service life of your rechargeable batteries.
After every charge/discharge procedure is complete, the charger adds a
short pause for the benefit of the rechargeable batteries before continuing
with the selected charging/discharging program.
ATTENTION: Please ensure that the rechargeable batteries are
designed for the respective charging current. For example, AAA
rechargeable batteries should not be charged with a 1500mA
or 1800mA charging current. We recommend choosing the
maximum charging current (mA) so that it does not exceed the
capacity value (mAh) of the inserted rechargeable battery.
it is normal that batteries may become warm during charging. After charging
is complete, the charger switches automatically to trickle charge. The trickle
charge prevents self-discharge of the batteries when left in the charger.

capacity in mAh/Ah.
‘ERR’ and ‘Lo’are displayed alternately if the rechargeable battery inserted
has an internal short-circuit and so is defective.
‘ERR’and ‘Hi’are displayed alternately if the rechargeable battery inserted
exhibits a very high resistance or a non-rechargeable battery is inserted. In
such cases, no charging occurs. Please remove the defective batteries and
dispose of these in an environmentally friendly manner.
During the charging process, the pre-set
parameters are displayed as mentioned
under point 3 (DISPLAY). In addition, the
chosen charging program and the current
process (CHARGE or DISCHARGE) are shown.
In the illustration above you can see an example of the LCD display. This
example shows 4 different display modes and 4 different charging programs.
Charging 9V rechargeable batteries
One 9V battery can be charged, if no D-cells are inserted in the inner round
cell charging slots. When inserting the 9V battery, pay attention to the correct
polarity referring to the symbol in the charging slot. The LED charging indicator
illuminates red when the battery is inserted correctly. 9V batteries are
charged with a gentle current of c.15mA. After approx. 24 hours, the charge
process ends automatically and the LED illuminates green. The rechargeable
battery is charged and will be supplied with the trickle charge current so long
as it remains in the device. If the indicator flashes red, the battery has an
internal short circuit and should be disposed of.

Operation Principle
Wet roof leak detection relies on the roof’s surface moisture forming an
electrically conductive path to earth via the building substrate.
The Wet Roof Pro’ utilises the conductive properties of water to allow the
operator to locate the source or origin of a leak. This method is also known
as voltage gradient mapping or vector mapping.
Fig. 11 shows a representation of how lines of equal voltage (similar to ripples
on a pond) may appear in a test area with a single fault and how the Wet
Roof Pro’ detector unit would display the measured potentials (voltage).
Fig.11 Principle of operation

Instruction Manual
20
The stainless steel trace wire is used to form a conductive perimeter around
the area of roof to be tested and is connected to the negative output of
the Wet Roof Pro’ generator unit.
The positive output of the Wet Roof Pro’ generator is connected to a suitable
earthed point of the building substrate. When the generator unit pulses a
voltage is applied to the trace wire, electrical current flows from the trace
wire toward the origin of the leak (denoted by the blue lines).
As current flows the measured voltage potential (Dark blue/black concentric
rings) decreases as the voltage approaches the leak origin.
It therefore follows that the further the survey probe are set apart, the greater
the number of directional chevrons that will be displayed. This is due to there
being a larger voltage difference between the two poles.
In fig.11 the difference between measured voltage potentials at probes A &
B is approximately 6.0 volts, the detector unit will therefore display direction
chevrons to the right (due to current flowing from left to right i.e. trace wire
to leak origin).
Probes at points C & D will show no direction because both probes are on
lines of equal voltage potential (20.0 volts) as are probes at points E & F.
As the detector unit displays the directional chevrons, it is the direction of
the chevrons not their magnitude that the operator is guided by.
The voltage potential or gradient within a test area can be somewhat
unpredictable due to several variables, these include salinity of the water
and the electrical resistance of the fault to building earth point. The greater
the moisture penetration between roof membrane and building structure
the greater the current flow will be.
