1 General Information
1.1 General Safety-Related Information
Carefully read the provided Operating Instructions and adhere to all Safety
Guidelines, prior to the use of this device.
All items which directly relate to the safety of the Operator and the error-free
operation of the electronic torquemeter, are marked in the Operating Instruc-
tions with the symbol shown left.
1.2 Intended Use
This electronic torquemeter has been designed and constructed for the sole purpose of
monitoring Piezo-Transducers-, Strain Gauge Transducers or external Rotary Type Trans-
ducers.
The use of this instrument in any other way is not acceptable. Furthermore DEPRAG is not
liable for damages, resulting from the misuse of the instrument; the user alone is liable.
The correct use of the instrument includes compliance with all Operating-, Maintenance-,
and Repair Instructions, which are considered an integral part.
The instrument can only be operated, maintained, and repaired by personnel familiar with
the device and who have been instructed about its dangers.
All relevant instructions in regards to accident-prevention, as well as general acknowl-
edged safety-rules and workers -protection regulations must be adhered to.
Arbitrary changes made to the device by the user will void the liability of the manufacturer
for resulting damages.

1.3 Technical Measuring Information
The Transducer (measuring platform/Dynamometer) 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 dis-
tortion of the measuring platform resulting from incorrect installation).
After each start-signal, the charge amplifier will reset and perform a zero calibration. Ex-
ternal forces, momentum, or vibration can distort the torque measurement.
IMPORTANT
For quality assurance and to keep accurate documentation for an audit, we
recommend to have your measuring instruments factory-calibrated every 12-
months.
We offer those types of calibration services for all our torque measuring in-
struments and transducers. We can also calibrate and certify your complete
measuring chain. Please contact us for additional information.

1.4 Machine Capability Testing
Prior to machine installation, this analysis can examine whether the applied production ma-
chine is even capable to accurately handle the production requirement.
The goal of a machine capability test is the confirmation, that
a) the machine to be tested operates using a clearly recognizable conformity. If not con-
formity is recognized, then the machine does not have a defined capability. It is then
not possible to assign a statistical capability-index to the machine.
b) the machine is capable to produce parts within predetermined tolerances. The neces-
sary evidence can only be generated using the conformity capability as shown under
item a).
The machine capability test is a short-term test, which sole goal it is to recognize machine
influences on the production process.
NOTICE
During sampling, no adjustments or errors may occur.
For this type of test, DEPRAG uses the Gaussian distribution curve.

IMPORTANT
The average torque should not deviate from the set value by more than 3%.
Otherwise a correct determination of the tool function index is not possible
anymore.
1.5 Functionality of the Measuring Instrument
This electronic torquemeter has been designed and constructed for the sole purpose of
monitoring Piezo-Transducers-, Strain Gauge Transducers or external Rotary Type Trans-
ducers in an industrial environment.
1.5.1 Piezo Electric Effect
The positive and negative loads of the piezo-electric effective dielectric materials are dis-
tributed unsymmetrical. Because of the molecules respectively the crystals, the center of
gravity of the positive loads does not subsidence with the negative loads. The piezo elec-
tric materials are electronically polarized.
When those materials are deformed, the dipole moment changes. On account of those
polarization changes, loads are being set free on the surface. Therefore, the piezo electric
effect can be used to obtain the load size from the measurement, which causes the defor-
mation. The freed load depends only on the deformation of the crystal and not on the
speed or the acceleration of the deformation.

1.5.2 Function of Piezo Measuring Transducer
The measuring transducers (MP25 / MP200 / MS25 / MS10) have piezo-quartz measuring
cells integrated. Because of the preloading of the cell during manufacturing, the emitting
electrical load (Coulomb) is determined. Since different cell sizes are available, the emit-
ting electrical loads of the transducers are different.
The engraved calibration values on the transducer define the emitted load (Coulomb) per
Newton - Meter (Nm).
i.e. if a force of 1 Nm is put to the measuring cell, a load is emitted, which is defined by the
calibration value.
Example for the calibration value: 172 pC / Nm
1 pico Coulomb = 0.000 000 000 001 C
The measuring electronic has a charge amplifier integrated, which transforms the emitted
electrical load from the transducer into an electronic voltage. The voltage depends on the
integrated capacitor, which is on the measuring input. i.e. at a range capacitor of 1000 pC,
a load of 2000 pC is converted into 2 V. Each measuring range is rated to +/- 5V.
1.5.3 Drift (Piezo Measuring Transducers)
A characteristic of the charge amplifier is the drift. This drift is caused by the input-
resistance of the input-transistor. Through this input-voltage, the charge amplifier drifts into
a positive or negative direction. Therefore, it is important, to start the measurement imme-
diately prior to the screw driving.
1.5.4 DMS-Bridge
The electrical resistance of each strain changes when deformed. The cause of this defor-
mation may be power, pressure, torque, deflection, angle, etc. The resistance of the de-
formed DMS (strain gauge) consists of its basic resistance R (no load) and the consequen-
tial occurring resistance-change R.

5 Installation and Connection
5.1 Power Cable
• Connect power cable to charger.
• Place measuring instrument ME5000 into charger, so that the batteries in the measur-
ing instrument may be charged.
• Once the green LED „Ready“ appears on the charger, the batteries are fully charged.
• When charging batteries for the first time, the charging process may take up to 2 hours.
IMPORATANT
When charging the battery-pack for the first time the green light starts
blinking after approx. 15 minutes (impulse trickle charging). If this happens
remove the unit from the charging point and then place it again into the
charging point.
Make sure, that the red light "Charge" (2) is on while charging the unit.
5.2 RS232 Port
If the measuring values need to be displayed on a PC or printed on a serial printer, then
the RS232 connection cable (standard) needs to be connected to the RS232 port on the
docking station and the PC or printer. Thereafter, all values can be output either in print
format or in csv-format (with customized DEPRAG software) on a PC or printer.
6 Software-Update
Software updates and PC-Software with connection-cable are available upon request.
