1. Introduction
Please take the time to thoroughly read this instruction
manual. It will help you with the installation, maintenance,
and use of this product.
To the extent permitted by law Kistler does not accept any
liability if this instruction manual is not followed or prod-
ucts other than those listed under Accessories are used.
Kistler offers a wide range of products for use in measuring
technology:

Signal conditioners, indicators and calibrators
Electronic control and monitoring systems as well as
software for specific measurement applications
Data transmission modules (telemetry)
Kistler also develops and produces measuring solutions for
the application fields engines, vehicles, manufacturing,
plastics and biomechanics.
Our product and application brochures will provide you
with an overview of our product range. Detailed data
sheets are available for almost all products.
If you need additional help beyond what can be found ei-
ther on-line or in this manual, please contact Kistler's ex-
tensive support organization.

2. Important Notes
It is essential for you to study the following information,
compliance with which is for your personal safety during
the work and will ensure long, fault-free operation of the
instrument.
2.1 For Your Safety
This instrument has been thoroughly tested and has left
the factory in a perfectly safe condition. In order to
maintain this condition and to ensure hazard-free oper-
ation, the user must comply with the information and
warning notes contained in these operating instructions.
The sensor must be installed, operated and maintained
only by persons who are familiar with the instrument
and are adequately qualified for the work concerned.
If it is accepted that safe operation is no longer possible,
the instrument must be shut off and made safe against
accidental start-up.
Safe operation must be assumed to be no longer possi-
ble when the product
Shows visible signs of damage,
has been overloaded,
is no longer operating,
has been in lengthy storage under unsuitable condi-
tions and
has been subjected to rough transport conditions.
Mount the sensor in position as prescribed. Details can
be found in Chapter 4.1.
Secure all parts mounted on the sensor according to
anticipated forces!

2.2 Unpacking
Check all packaging for transport damage. Report any such
damage to the transporters and to the authorized Kistler
distributor.
2.3 Notes on Handling the Instrument
The sensor must be used only under the environmental
and operating conditions specified.
With piezoelectric sensors, insulation resistance is of
crucial importance; it must be approx. 1014 (but not
less than 1013 ). In order to preserve this value, all
plug-and-socket connections must be kept absolutely
clean and dry. The insulation resistance can be meas-
ured with the insulation tester Type 5493.
Protect the connector of the sensor against contamina-
tion and on no account touch it with your fingers (con-
nector front). Fit the cover supplied over the connector
when it is not in use.
A high-insulation cable is used to connect the sensor to
a charge amplifier. Once fitted, it should if possible
remain connected to the sensor. Use only specified con-
necting cables.
Protect the sensor when it is not in use by storing it in
its original packaging.

2.4 Tips on the Use of this Instruction Manual
We recommend you to read through the entire instruction
manual. However, if you are in a hurry and already have
experience with Kistler 3-component force links, you can
restrict yourself to the specific information needed.
We have endeavored to give these instructions a neat
layout to make it easy for you to gain direct access to the
information you require.
Please keep these instructions in a safe place where they
are always to hand.

3. General Description of the Instrument
3.1 What is the Purpose of a 3-Component Force Link?
The 3-component force link is used for the dynamic and
quasistatic measurement of the three orthogonal compo-
nents of any force acting on the sensor (Fx, Fyand Fz).
3-component force links measure:
Cutting forces during machining
Impact forces in crash tests
Recoil forces of rocket engines
Vibration forces of components for space travel
Friction forces
Forces in product testing
Ground reaction forces in biomechanics
Vehicle forces on a road and a test stand
Forces on a wind tunnel balance
