1 Safety instructions
Use in accordance with the regulations
The TTS Transfer torque wrench may be used for torque measurement and
calibration tasks only. Use for any additional purpose shall be deemed to be
not in accordance with the regulations.
In the interests of safety, the transducer should only be operated as described
in the Mounting Instructions. It is also essential to observe the appropriate legal
and safety regulations for the application concerned during use. The same
applies to the use of accessories.
The transducer is not a safety element within the meaning of its use as
intended. Proper and safe operation of this transducer requires proper trans
portation, correct storage, assembly and mounting and careful operation.
General dangers of failing to follow the safety instructions
The transducer corresponds to the state of the art and is fail‐safe. The
transducer can give rise to remaining dangers if it is inappropriately installed
and operated by untrained personnel.
Everyone involved with the installation, commissioning, maintenance or repair
of the transducer must have read and understood the mounting instructions
and in particular the technical safety instructions.
Remaining dangers
The scope of supply and performance of the transducer covers only a small
area of torque measurement technology. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety
engineering considerations of torque measurement technology in such a way
as to minimize remaining dangers. Prevailing regulations must be complied
with at all times. Reference must be made to remaining dangers connected
with torque measurement technology.
In these mounting instructions, remaining dangers are pointed out using the
following symbols:

Application
TTS A01571_04_Y00_00 HBM: public 7
3 Application
The transfer torque wrench is used as a transfer standard for calibrating torque
wrench calibrating devices.
Generally, when a torque wrench calibrating device is used, torque is gener
ated by exerting force on the lever of the torque wrench to be calibrated (e.g.
the triggering torque wrench to be used in the workshop). When calibrating the
torque wrench calibrating device, on the other hand, a transfer torque wrench
(the indicating torque wrench) is inserted into the calibrating device instead of a
torque wrench in need of calibration. The torque is generated in the same way
as for normal use, so that the measurement conditions for the calibrating
device are identical. This is of particular importance with respect to the para
sitic loads acting at the same time as the actual calibration torque, namely lat
eral force and bending moment.
The design of the TTS transfer torque wrench is adapted to German Calibra
tion Service guideline DKD‐R 3‐8 1), which regulates the calibration of torque
wrench calibrating devices.
To conform to the strict requirements regarding the traceability of a transfer
standard, a transfer torque wrench must be calibrated in an accredited calibra
tion laboratory (in Germany, this is a DKD laboratory). The DKD calibration
certificate in accordance with guideline DKD‐R 3‐7 2) has to be ordered sepa
rately.

lished by the German Calibration Service.

4 Structure and mode of operation
4.1 Mechanical construction
The transfer torque wrench comprises a measuring head and a lever. A mea
suring body and an interchangeable square adapter are integrated in the mea
suring head. The supplied connecting cable is connected with the transducer
via a six‐pin Lemo®socket.

CAUTION
The hexagon‐socket screws on the measuring head are marked with a locking
varnish and must not be loosened!
4.2 Installation position
The transfer torque wrench can be mounted in any position. With a clockwise
torque, a positive output signal is produced in conjunction with HBM measuring
amplifiers.

4.3 Conditions at the usage site
The transfer torque wrench is protected to IP22 according to EN 60529.
Transducers must be protected against coarse dirt particles, dust, oil, solvents
and humidity.
During operation, the prevailing safety regulations for the security of personnel
must be observed.
Assembling the torque wrench
10 A01571_04_Y00_00 HBM: public TTS
5 Assembling the torque wrench
The transfer torque wrench is taken apart and delivered in a carrying case. The
measuring head, the square adapter, the knurled screw, the lever and the con
necting cable are all separate. Depending on the nominal (rated) torque, there
are one, two or three parts to the lever.
CAUTION
If you want to use a different square adapter from the accessories program,
instead of the one supplied, you must keep to its maximum permissible torque
(see Section 9, Page 19).
5.1 Fitting the square adapter on the measuring head
Notice
We recommend that the square adapter is always installed in the same angular
position. The later transfer torque wrenches have arrows on the measuring
head and on the square adapter for ease of positioning (see Fig. 5.1). The
points of the arrows should point to one another.

Position the square adapter in accordance with the arrow markings (see
Fig. 5.1) on the measuring head; insert the knurled screw into the central hole
in the measuring head and screw the square adapter in tight.
Information
By keeping to the same angular position, any symmetry deviation will not affect
the reproducibility of the measurement results.
5.2 Fitting the lever
Depending on the nominal (rated) torque, there are one, two or three parts to
the lever. To make assembly easier, apply a little oil to the mating surfaces of
the individual components.
5.2.1 One‐piece lever (nominal (rated) torque 100 N@m)
SPress down the spring bolts of the lever.
SPush the lever as far as it will go into the receiving hole in the measuring
head.
STurn the lever from side to side until you hear the spring bolts engage.

Electrical connection
14 A01571_04_Y00_00 HBM: public TTS
6 Electrical connection
6.1 General instructions
Electric and magnetic fields often cause interference voltages in the measuring
circuit. This interference comes primarily from power lines lying parallel to the
measuring leads, but it can also come from nearby contactors or electric
motors. Interference voltage can also be coupled galvanically, especially by
grounding the measurement chain at a number of points.
Please follow the below instructions:
SUse only shielded and low‐capacitance measurement cables for six wire
circuit from HBM.
SDo not position the measurement cables parallel to power lines or control
circuits. If this is not possible (e.g. in cable shafts), protect the
measurement cable with armoured steel tubing, for example and keep it a
minimum distance of 50cm away from the other cables. Power lines or
control circuits should be twisted together (15 twists per meter).
SGuard against stray fields from transformers, motors and contactors.
SDo not ground the transducer, the amplifier and the indicator more than
once. All the measurement chain devices must be connected to the same
grounded conductor.
Grounding concept (Greenline)
The cable shield of the connection cable is connected to the measuring head of
the transducer. This encloses the measurement system in a Faraday cage.
Any electromagnetic interference active here does not affect the measurement
signal.
In the event of interference due to potential differences (equalization currents)
the zero operating voltage and the housing ground should be isolated from one
another at the amplifier and a potential equalization line should be run between
the housing and the amplifier housing (flexible stranded wire, 10 mm2
conductor cross‐section).

6.2 Connector pin assignment
The transfer torque wrench comes supplied with a ready‐made 6‐wire
connection cable (six‐wire circuit).

Extension cables should be of the shielded, low‐capacitance type. HBM pro
vides the 1‐KAB254‐10 cable (ready‐made) and the KAB8/00‐2/2/2 cable (by
the meter, can also be supplied with fitted connecting plug) specifically for this
purpose.
