1 Introduction
1.1. Structure of the FDM-T system user manual
The FDM-T measuring system consists of a treadmill, the pressure distribution measuring sensors,
and the corresponding application software, including the PC. The sensors and treadmill can also
be used completely independently of each other and feature a separate power supply and CE mark.
The user manual for the FDM-T measuring system therefore consists of several sections:
1. FDM-T specifications and hardware user manual
2. zebris FDM user manual for the application software
3. Specifications and user manual supplied by the treadmill manufacturer.
4. User manual and specifications of accessories like projector or PC
The section FDM-T specifications and hardware user manual mainly contains information regar-
ding the specifications and operation of the FDM-T pressure distribution measuring sensors and
their safe operation in combination with the treadmill, as a measuring system. Instructions regarding
the treadmill are restricted to the main safety and servicing measures.

All FDM-T systems can be stored without power supply for a maximum
of 6 to 9 months. After this period, the battery may be totally discharged
due to lacking power supply. If the storage of the device exceeds this period,
a reprogramming of the treadmill control may be necessary.
FDM-T 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 measuring
system is not protected against the entry of liquids. Liquids penetrating
the device can cause fire, electrical shock, or other severe accidents.
The FDM-T system is NOT specified for the operation in vacuum, hyper-
baric 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.
Therefore, the devices must be protected against humidity.
The ventilation slots of the treadmills must be always free, so that
air can circulate freely.

2.2.3. Safety instructions for the treadmill
■The treadmill belonging to the FDM-T measuring system is a very powerful device.
For safe operation of the FDM-T system it is mandatory to adhere exactly to the
safety regulations described in the following.
■The measuring procedure on the treadmill must never be commenced without a thorough
instruction of the patient by trained personnel. No measurements may be taken without a supervisor.
■Do not place the treadmill on an unstable ground.
■Do not set up the system near a source of heating or in direct sunlight in front of a window as
a strong rise in temperature can lead to inaccurate measuring results.
■Directly behind the treadmill it is mandatory for a safety zone of 2 m in length and 1 m in width
to be kept free, and ought to be padded (with a soft mat). No items may be left in this zone during
operation (such as video camera, lighting equipment etc.).
■Dangerous drawing-in gaps are located at the rear end of the running belt and along its sides and
(if existing) on the elevating mechanism. Do not wear any loose clothing that could get caught up
in the rollers. Make sure that if a person trips over, their long hair, loose clothing, jewellery, etc.,
do not encounter the rear part of the treadmill belt (e.g., wear a hair net). Due to danger of
stumbling, do not place any clothing or jewellery on or within close proximity of the treadmill.
■Never use the treadmill without the safety clip being fastened to your clothing and always be sure
that the folding mechanism (if existing) is properly locked during operation. (Please also be sure to
read the safety instructions in the user manual supplied by the treadmill manufacturer.)
■During operation, the emergency STOP facilities must always be within easy reach for the user and
the operating personnel.
■The patient should walk slowly to begin with. Then gradually speed can be increased after a few
minutes, depending on the patient’s physical condition. Improper or excessive strain through tests
resp. measurements can have harmful effects on health.
■Never jump onto the running belt and never jump off it whilst it is running. Never stop walking
while the treadmill is running, never turn round or step sideward or backwards. Should movement
patterns of this kind be necessary for your measurements, please make sure to use a type of tread-
mill with a safety arch, protection against falling and a “fall stop” chest belt.
■Pull out the power plug before transporting the treadmill.

2.2.4. Prohibited use
■Improper and/or prohibited use of the measuring system is impermissible and zebris
warn explicitly against all prohibitions included in this section.
■Do not try to service the treadmill in any manner other than that described in this user manual.
By the removal of the protective covers, it is possible that you could expose yourself to lethal high
voltages or other hazards.
■We also point out that if any changes are made to this certified device or its accessories without
the prior written consent of zebris, your legal right to operate the device will be void. If changes
are made to the device without obtaining approval, the operator is obligated to carry out suitable
investigations and tests to guarantee safe use.
■It is prohibited to embed the treadmill in the floor to reduce (track) access height. This way of
installation might create a highly dangerous capture area at the rear guide pulley of the treadmill.
The zebris Medical GmbH expressively will undertake no liability for injuries to any person when
the treadmill is operated under such condition!
■All applications using wheels are prohibited (cycling, wheelchair, inline skating or roll ski) as well
as running shoes with spikes or studs. Besides their extremely high risk of injury, these can cause
irreparable damage to the sensors.
■There should never be more than one person on the treadmill at a time once it is in operation.
■Children and animals are not allowed to use the treadmill without supervision and must maintain
a safety distance of at least 5 m.
■Any manner of over-exerting the test persons is strictly prohibited. In cases of nausea and dizziness,
the measuring is to be discontinued immediately and a doctor consulted.
■Any form of operation involving an increased hazard is strictly prohibited, e.g., sprinting or also
using test persons having an increased risk.
■
The use of the measuring system under the influence of alcohol, drugs or narcotics is strictly prohibited.
■zebris measuring systems may not be operated in any other environmental conditions than those
listed in the section: 3.3. Technical specifications, p.13, (e.g., in wet zones, moisture-prone areas,

3.4. Measuring principle FDM-T systems
The system contains a measuring matrix consisting of capacitive pressure sensors that are arranged
in columns and lines running closely next to each other. For determining the pressure distribution
over the measuring matrix, the capacity proportional to the pressure exerted is determined for each
individual sensor. To do this, the drive logic generates several sinus burst signals equivalent to the
number of columns via the column decoder and transmits them to the respective measuring column.
The analogue signal coupled into the shift register over the lines is proportional to the pressure-dependent
capacity and is passed on for further processing to the control and signal-processing electronics and
transmitted to the PC from there and shown on the display.
Schematic circuit diagram of the measuring system

The correct synchronisation of all measurement data must be verified in case
devices are connected to zebris SYNC which have not been manufactured by
zebris Medical GmbH. zebris does not accept any liability for correct function
and reliability of the system if the clock signal of external devices does not
comply with the signal specifications provided with in this user manual.

3.7.1. Synchronization Input (SYNC-IN)
If a third-party device is connected to the synchronization input SYNC-IN then depending on
the setting of the configuration window from the application software the measurement will
start/stop or “sample by sample” synchronized by a signal from the third party device.
Input is protected against faulty polarisation and pin 1 is set to +5V (”1”) by an internal pullup-
resistor (2.7 k). If this input is set to 0 V (”0”) i.e., by a switch or break contact than the
SYNC-IN is triggered.
