Introduction
Thank you for purchasing PCE-DDM series crane scales from PCE Instruments.
These crane scales which are made of high-quality materials are perfectly suitable for mobile tension
measurements, e. g. as carried out by consultants. They have a high measurement capacity but are also
compactly constructed with a low net weight.

Safety notes
2.1
General
Please read this manual carefully and completely before you use the device for the first time. The device
may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no
warranty of damage or injuries caused by non-observance of the manual.
- The device may only be used in approved temperature ranges as laid down in the specifications.
Exposure to extreme temperatures, direct sunlight, extreme atmospheric humidity or wetness (e. g. wet
hands) must be avoided.
-
The case must only be opened by qualified personnel of PCE Instruments.
- The instrument should never be placed with the user interface facing an object (e.g. keyboard side on a
table).
- You should not make any technical changes to the device.
- The appliance should only be cleaned with a damp cloth / use only pH-neutral cleaner, no abrasives or
solvents.
- If you do not use the device for a longer period of time, remove the batteries.
- The device may only be used with PCE accessories or equivalent.
- Do not use the device in potentially explosive atmospheres.
- Do not weigh more than the maximum capacity.
- To avoid hazards arising from load lifting, the producer as well as the user have to comply with certain
duties. The use of the measuring equipment may at no time be hazardous.
- The person responsible for the measuring equipment as well as the user must observe and fulfill the
national regulations, e. g. regulations for accident prevention, safety regulations, work protection
regulations and all other regulations applicable for the use of the measuring equipment.
- Other directives such as regulations and safety information for the use of the measuring equipment must
be borne in mind, for example those of the crane producer, of the load suspension device producer and of
the shackle producer.
- In this relation, the measurement equipment may only be mounted, put into service, maintained and
operated by qualified personnel using appropriate protective equipment.
- The measuring equipment must not be changed and may only be used for intended purposes.
- The measuring equipment as well as all other equipment (e. g. the crane, the load suspension devices
etc.) must be maintained, serviced and accordingly recorded regularly. Before each use of this
equipment, you should at least visually inspect it. In case the equipment is incomplete or damaged (e. g.
cracks, deformations, split-offs) the equipment must be taken out of service. It is urgently necessary to
get advice from your company’s responsible safety representative regarding this matter.
- Repairs may only be carried out by qualified personnel and only quality-tested spare parts must be
used. All repairs, maintenance work and spare parts must be documented by the service partner.
- The manual as well as the safety notes should always be with the measuring equipment.
- The measuring equipment is
not ex-protected
and may not be used in potentially explosive
atmospheres. The environmental conditions such as the temperature ranges can be seen from the
manual and must be adhered to. Aggressive or corrosive areas of application must be avoided. When the
temperature fluctuates severely, an acclimatization period must be included.
- The measuring equipment is only approved for lifting and weighing freely-moveable loads. Torsion
(torsional stress) of the load is not allowed. Carrying persons, pulling, tearing, towing etc. of loads is
prohibited.
- The permissible nominal load [MAX] of the measuring equipment and other equipment in use (e. g.
crane, lifting fixation device etc.) may under no circumstances be exceeded.
- When you use the equipment, you must always observe the possible danger zone. Do not enter the
danger zone during use. This does not only include the area directly under the load but also the areas
which can be dangerous due to e. g. swinging ropes or other load suspension devices.
