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 mean
ing of its use as intended. Proper and safe operation of
this transducer requires proper transportation, 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 particu
lar 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 instructions
4A1571-3.0 HBM: public TTS
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 A1571-3.0 HBM: public 7
3 Application
The transfer torque wrench is used as a transfer stan
dard for calibrating torque wrench calibrating devices.
Generally, when a torque wrench calibrating device is
used, torque is generated 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 cali
brating 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 gener
ated in the same way as for normal use, so that the mea
surement conditions for the calibrating device are identi
cal. This is of particular importance with respect to the
parasitic loads acting at the same time as the actual cali
bration torque, namely lateral force and bending moment.
The design of the TTS transfer torque wrench is adapted
to German Calibration Service guideline DKD‐R 3‐8 1),
which regulates the calibration of torque wrench calibrat
ing devices.
To conform to the strict requirements regarding the trace
ability of a transfer standard, a transfer torque wrench
must be calibrated in an accredited calibration laboratory
(in Germany, this is a DKD laboratory). The DKD calibra
tion certificate in accordance with guideline DKD‐R 3‐7 2)
has to be ordered separately.

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

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 parti
cles, dust, oil, solvents and humidity.
During operation, the prevailing safety regulations for the
security of personnel must be observed.

Assembling the torque wrench

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 connecting
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 Sec
tion 9, Page 21).
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.

Information
By keeping to the same angular position, any symmetry
deviation will not affect the reproducibility of the mea
surement 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.

Electrical connection

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 electro

Electrical connection
TTS A1571-3.0 HBM: public 17
magnetic 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 mm2conductor cross‐section).
6.2 Connector pin assignment
The transfer torque wrench comes supplied with a
ready‐made 6‐wire connection cable (six‐wire circuit).
The pin assignment for the HBM amplifier can be found
in the following table:

5 black Excitation voltage (-UB)
6 blue Excitation voltage (+UB)
8 white Measurement signal (+UA)
12 gray Sensor circuit (-)
13 green Sensor circuit (+)
15 red Measurement signal (-UA)
Extension cables should be of the shielded, low‐capaci
tance type. HBM provides 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.
