2 Safety Instructions
Reading the enclosed safety instruction booklet no. 016000 (pink-coloured booklet) is
essential for working with the equipment.
WARNING
Fires, electric shocks and other injuries, or damages to components can be
caused if the safety guidelines are ignored.
WARNING
Risk of fatal injury due to electrocution!
Disconnect the electric equipment from the power supply before starting
any work on the tool (e.g. installation, changing of accessories or machine
tools, removal of covers prior to longer downtimes, maintenance works,
etc.).
Switch off the mains switch and pull out the mains plug!
3 Intended Use
This measuring instrument has been designed and constructed for the sole purpose of

5 Short Description
The ME6000 is a measuring device, which is designed for measuring using DMS
measuring platforms, piezo measuring platforms/torque wrenches and external
transducers. DMS platforms and external transducers, either from DEPRAG or from
other manufacturers can be connected.
It is operated by use of the delivered software. The software is available in various
languages.
The calibration value can be set for the chosen sensor. There are three options for
measurement: measurement using start/stop, measurement with automatic end
recognition and with series recognition. The seria n operates with au
end recognition.
You can choose from various measuring units t he measurement resu
required you can enter limit values for the measurement results. Then the measurement
value is shown highlighted in colour whether the measurement results are inside or
outside the measurement values.
he process of measurement (screw assembly) is displayed graphically if required. The
graph can be labelled with markers. A zoom function enables easy evaluation of a
screw assembly. The measurement data can be saved in a file and reloaded later. The
measurement graph can be saved in either bitmap or jpg format and also directly used
in other applications using copy and paste.
Statistical evaluations are calculated by average, standard deviation and standard
deviation in percentage. The machine performance index (Cmand Cmk) is calculated by
means of the set tolerance in relation to the average value. The tolerance is given in
percentage. Alternatively the upper and lower limits can also be altered.
The analogue instantaneous value display constantly shows the measurement value
which is measured on the measuring platform or with an external transducer.

not necessary to input the same data twice.

10.1 General Function
If
.
10.2 General Measurement/Technical Information
The Transducer (measuring platform/Dynamometers) has to be positioned on a solid
base, without allowing any movement.
At that time the transducer should be free of external forces or vibrations (such as the
distortion of the measuring platform resulting from incorrect installation).
After each start-signal, the charge amplifier will reset and perform a zero calibration.
External forces, momentum, or vibration can distort the torque measurement.
In order to provide a high level of quality assurance and for you to be able to present the
respective documents in case of an audit, we recommend to have your measuring
devices re-calibrated once a year.
Concerning our torque measuring units and torque dynamometers as well as for a
complete measuring series we would like to offer you to have these calibrated at the
DEPRAG Amberg facilities.

10.3 Test of Tool Function Capability
Prior to the use of a tool for the mass production, it can be testes, if this tool fulfils the
required demands with sufficient safety margin.
The goal of a Function Capability Test is to proof that:
a) the tool to be tested conforms to recognized regulations. If no regulations are
recognizable, then the tool does not have a defined capability. It is then not
acceptable to assign statistical calculated capability values to such a tool.
b) the tool is capable to assemble parts within defined tolerances. The required proof
can only be established using the recognized regulations, as shown under a).
The function capability test is a short-term test, with the goal to obtain exclusive
machine-conditions that influence the manufacturing process.
