5.3 Checking the functional interaction
of both devices
m Before checking, switch off both devices. Set
the rotary switch of pulse receiver PD200 E
M
to "TEST". If the switch is in a different
position, the receiver might be damaged
when switching on pulse generator PD200 G.
Use the red
9
and black 10 connection cables to
connect the pulse receiver to the receptacles of the
pulse generator
H
I. Ensure the correct colour
assignment black/red.
Switch on the generator. Then switch on the receiver
and use the rotary switch
K
to adjust the indicator
to "0".
The needle of the analogue indicating instrument [µA]
L
must deflect to the right in the pulse frequency.
Also check the pulses by means of the green lamp
B
in the transport case. Switch on the acoustic
signal of the pulse generator
F
.
Interchange the two measuring lines at the pulse
receiver – black cable to red connector and red cable
to black connector – and repeat the procedure. The
needle should now deflect to the left.

06. Leak detection
6.1 General functioning
The method is based on the fact that there is water
both on top of and also underneath the sealing sheet.
This water or moisture serves as conductor. Therefore, leak detection always requires a damp and
hence electrically conducting sealing sheet, regardless of whether the surface is wet to various degrees,
gravelled or greened.
The PD200 pulse generator gives of current pulses
with a voltage of 40 V. The current finds its path to the
point of leakage via the moisture. The PD200 receiver
is used to measure the potential difference. The
needle of the indicating instrument deflects to the
direction with the higher potential, indicating the
direction for the locator. This way you are led to the
leak, to the position where moisture enters.

6.3 Preparation warm/green roof
6.3.1 Installation of loop wiring
Figure: sectional drawings warm roof
loop wiring
fill
loop wiring
fill
Before measuring, the bare cord 4 (loop wiring)
is to be laid as closed circuit around the roof
area to be examined observing a minimum
distance of 0.5 m to the roof edge. Current can only
flow when the wire is placed directly on the roof
seal. If the fill consists of gravel or other granulated
material, we recommend the gravel claw (art.
no. 3.510.010.003) as optional accessory. In case
of thicker coatings, e.g. soil or greening, the roof
seal has to be exposed to enable direct contact
of loop wiring and roof seal.
At any rate, the roof seal to be checked must be sufficiently damp to conduct the current pulses. The roof
seal may have to be watered additionally.
6.2 Preparing the measurement
The basic distinction of flat roofs is made
between warm, cold and greened roof. Their
different composition necessitates a different
preparation.

6.3.2 Using the gravel claw (optional accessories)
The gravel claw serves the purpose of simplified
laying of loop wiring under the gravel fill.
Screw the gravel claw (art. no. 3.510.010.003) to
the bottom part of the measuring rod, which is not
intended for uncoiling the loop wiring (measuring rod
1). Now push the loop spindle onto the handle part
of the other measuring rod (measuring rod 2), which
serves as uncoiling aid, and secure the spindle by
means of the corresponding clamping spring.
Uncoil some of the loop wiring (approx. 1 m) and
attach it to a fixed position on the roof in a way that it
cannot shift, e.g. by weighting it down with an object.
Now tighten the wire and thread it into the eye of
the gravel claw. Hold spindle and gravel claw as
illustrated below. Carefully insert the claw in the
gravel by pulling and move backwards one step at a
time, so that the loop wiring disappears underneath
the gravel fill. On a sample basis check that the loop
is placed directly on the roof membrane.
m Always ensure sufficient protection for
all works on the (flat) roof! Particularly in
close proximity to the roof edge there is the
ever-present risk of falling!

6.3.3 Connecting the pulse generator
Connect the pulse generator to the mains. For this,
the device must be switched off. Make sure that the
earthing is switched on at the pressure switch
G
:
The red positive connector and the red
connection cable are not being used here.
Earthing is effected via the earthing contact
of the mains plug. The black connection cable
3
is connected to the loop wiring by use of the clip
terminal.
6.3.4 Connecting the pulse receiver
Both measuring rods are screwed together and
connected to the pulse receiver by use of the red and
black connecting cables.
6.4 Preparation cold roof
Timber structures are electrically non-conducting.
Therefore, the preparations differ.
6.4.1 Installation of loop wiring
Please proceed as described in point 6.3.1.

Please proceed as described in point 6.3.3.
Operating manual – pulse current measuring system PD200

6.5 Detection
First switch on the pulse generator and then the pulse
receiver.
Position yourself parallel to a roof side, seize the
two measuring rods by the rubber grips and with a
distance of approx. 1.5 m push them carefully through
the fill (gravel, greening) onto the roof seal.
m Avoid applying too much force, for
otherwise you will inadvertently puncture
the roof membrane!
m Measuring will only be possible when there
is contact to the roof seal, otherwise no
current flows through the receiver.
Pulses will now be indicated on the pulse receiver's indicating instrument. Should the deflection be
hardly discernible, reduce the resistance at the pulse
receiver by use of the rotary switch from "4" to "3"
or lower.
m Relevant for detection is NOT the degree of
needle deflection, ONLY the direction.
Start locating. If the needle now deflects e.g. to the
right, then move another step to the right. Keep going
like this until the needle deflects to the left for the
first time. At this point turn your body by 90° and
again follow the needle deflection. When the needle
deflection again changes its direction, reduce the
space between the measuring rods and repeat
the above procedure until you detect the precise
location of the leak. Having removed the fill, the leak
should be visible and can be repaired.
07. Avoiding measurement errors
By earthing the positive pole (see 6.3.3) on the roof,
everything grounded will be indicated. As a result
you are easily led to a lightning arrester, because it
contacts the fill. To avoid this you can either prevent
the connection of grounded parts to the roof e.g. by
placing insulating tape or foil underneath or neutralize
the earthing of these parts e.g. by disconnecting the
lightning protection. Earthed drains (metal drains) are
to be shielded.
7.1 Shielding
If insulation or the removal of an earthing is not an
option, as is the case for e.g. drains or ventilation
shafts, this area is to be shielded. To do so, a closed
loop is installed around this area and connected to the
outer main loop. This way it is also possible to shield
leaks which have already been detected in order to
then proceed with another detection process.

7.2 Supposed leak at the centre of the measuring
surface
If with a decreasing deflection you are led toward the
middle M1 of the indicated field, there probably is no
leak. To check this, install some test wiring which is
connected to the loop approx. 1 m beside the measured spot M1. If the previously determined point of
leakage M1 shifts away from the test wiring toward
M2, there is no leak.
7.3 Prolonged drought
In case of prolonged drought the fill is to be prepared
for measurement by means of generous watering. On
roofs without fill a moisture film is all it takes, as long
as it covers the entire area. Cold roofs might necessitate a certain waiting period.
7.4 Earthed metal parts
In order to ascertain whether the metal parts on the
roof are grounded, use the black connection cable
3
and briefly contact the clip terminal to the respective
surface of the metal part. Make sure that the earthing
is switched on at the pressure switch
G
. If a loud
acoustic signal is emitted and the warning
light
A
lights up in red, the metal part is
grounded.
08. Checking of lined ponds and swimming
pools with non-conducting sealing
First measure the floor area of swimming pools.
Following the floor, the walls can be checked for leaks
one by one. For this purpose the loop wiring is affixed
by use of adhesive tape. Lined ponds, too, can be
examined with a loop around the outer rim. However,
the foil here has to be visibly exposed. The measurement is effected by applying the same method as on
the roof. Here, too, sufficient moisture covering the
entire area is required for the measurement.
