1.2 Structure of the PDM System user manual
The measuring system PDM consists of the force distribution measuring sensor technolo-
gy as well as the corresponding application software including a PC.
Therefore, the user manual of the PDM measuring system consists of several parts:
Part 1 - PDM technical specifications and user manual
Part 2 - User manual for the zebris FDM application software
Part 3 - User manual of the accessories, like e.g. projector or PC
NOTE
Please closely observe the user manuals with initial operation,
use or maintenance as well as transport of the PDM measuring
system.
Part 1 - PDM technical specifications and user manual primarily contains information on
technical data and the operation of the PDM pressure distribution measuring sensor tech-
nology as well as on their safe operation.
WARNING
The precise adherence to the instructions in all sections of the oper-
ating Instructions for the measuring system is a precondition for its
intended use.

2 Safety
2.1 Environmental conditions
PDM Measuring Systems are suitable for application in dry interiors with level ground such
as those in hospitals, doctors' surgeries and laboratories.
Temperature 10°C to 40°C
Relative humidity 30% to 70%, non condensing
Air pressure 700 to 1100 hPa
WARNING
PDM systems must NOT be operated in wet zones, wet rooms
(swimming pools, saunas) or climatic chambers.
Direct contact with liquids must always be avoided, as the measur-
ing system is not protected against the entering of liquids. Liquids
entering the device can cause fire, electrical shock or other severe
accidents.
The PDM system is NOT specified for the operation in vacuum, hy-
perbaric or altitude chambers.
The measuring systems are not intended for operation in potentially
explosive atmospheres of medically used rooms or oxygen-enriched
atmospheres.
The devices must not be operated in proximity to e.g. engines or
transformers with a high connected load as well as mains current
lines, as electrical or magnetic interference fields can falsify correct
measurements resp. turn them impossible.
2.2 Storage and Transport
Storage and transport of the measuring system are only to be effected in the original
packaging provided by zebris.
Temperature -20°C to +70°C
Relative humidity max. 95%, non condensing
Protect from moisture

2.4 General safety instructions
The application and operation of the system and also the evaluation of the measuring
data and their interpretation may only be carried out by trained qualified personnel. The
manufacturer assumes no liability for any injury to persons, damage to property, or loss
of data due to improper use of the software, the device or its component parts.
Measuring data may only be copied, moved, or deleted using the data-base function
provided by the zebris application programs. In the case of data being changed inten-
tionally without using the database functions, the user alone bears full responsibility for
all risks involved.
Should there be any detectable damage to the device or component parts, they should
be returned to the manufacturer for a safety check. It is not permissible to continue us-
ing the device or its component parts, as severe damage and serious injuries - even le-
thal injuries - may result. The manufacturer or authorized sales partner must always be
contacted in all cases of fault or doubt.
If any fluids should penetrate the device, it is mandatory for the device to undergo a
technical safety test. Damaged plug connectors and leads are to be replaced by an au-
thorized service technician. The device must be put out of operation immediately,
marked as "Not working“ and prevented from being used by removing the mains cable.
The measuring system must be checked at regular intervals to make sure it is function-
ing properly. More details on this can be found in the section, "Maintenance of the De-
vice" in this User Manual
Be sure that all the mains and connection cables are laid safely and that they are pro-
tected against stepping on, so that nobody can trip over them. Check all the cables and
the connection plug regularly for any damage. Damaged power supplies and cables
have to be replaced before further operation
Never try to service the measuring system in any other way as described in the provid-
ed user manual. When removing the covers, you may expose yourself to lethal voltages
or other risks.
We also point out that if any changes are made to this certified device or its accessories

3.5.4 Connection of two PDM-L Platforms (Inter-PDM IR-SYNC)
Two platforms of type PDM-L can be coupled (Master –Slave) in order to double usable
walking range. For this purpose an infrared interface (Inter-PDM IR-SYNC) is integrated in
the housing at the end of each platform.
NOTE
For connection arrange both platforms a shown in the picture below.
The front ends must point the outer side.
Both platforms must be connected to separate USB sockets oft the same PC. The zebris
FDM software will recognize the platforms automatically and display the extended meas-
urement area accordingly.
NOTE
In connected mode zebris SYNCCam and SYNCLightCam must be
connected to the SYNC socket of the master platform.

4 Video-Modul
4.1 SYNCCam
The SYNCCam is an accessory of the PDM system and perfectly adapted to be used in
combination with the force distribution measurement. All adjustments of the camera are
carried out via hardware setup integrated to the zebris FDM Software. The camera is con-
nected to the PC by a USB cable of type A-B included within the shipment.
The camera is equipped with ¼ inch tripod threads and can be adapted to zebris tripods
as wells as commercially available camera tripods.
WARNING
The Sync-LEDs are flashing when the camera is disconnected from
the USB port. Therefore it is strongly advised not to look directly into
the camera when it is disconnected in order to avoid dazzling.

4.2 SYNCLightCam
The SYNCLightCam is an accessory of the PDM system and perfectly adapted to be used
in combination with the force distribution measurement. All adjustments of the camera are
carried out via hardware setup integrated to the zebris FDM Software. The camera is con-
nected to the PC by a USB cable of type A-B included within the shipment.
The SYNCLightCam is equipped with ¼ inch tripod threads and can be adapted to zebris
tripods as wells as commercially available camera tripods.
WARNING
The Sync-LEDs are flashing when the camera is disconnected from
the USB port. Therefore it is strongly advised not to look directly into
the camera when it is disconnected in order to avoid dazzling.
Furthermore contains the SYNCLightCam as an integral solution, the LED video illumina-
tion.
In order to produce well lighted and tack sharp video captures it is essential to maintain
perfect lighting conditions at the patient’s side. Only with adequate lighting conditions
video cameras can work with shutter times short enough to freeze fast movements and
capture sharp images.
This solution is perfectly matched on the interaction with the PDM system and can be
regulated infinitely in its brightness.
The integrated synchronization unit automatically switches the lights on at the start of a
measurement and turns them off again after stopping it.
NOTE
In order to ensure save operation of the SYNCLights it is mandatory
to keep the black heat sinks at their back side uncovered and well
air circulated at all times.
