1. INTRODUCTION
NOTE:
The present manual is updated for the product it is sold with in order to grant an adequate
reference in operating and maintaining the equipment.
The manual may not reflect changes to the product not impacting service operations.
The rebound number determined by this method can be used to assess the uniformity of
concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in
structures.
This NDT test method is not intended as an alternative for the compressive strength
determination of concrete, but with suitable correlations already saved in the instrument,
it can provide an estimate of in situ compressive strength. The EN 13791 suggests the
procedure for a specific correlation to the concrete under test.
The hammer may be used for comparative testing, referenced against a concrete with
known strength or against a concrete verified as conforming to a particular strength class.
The test hammer 58-C0181/DGT is supplied complete with:
•Multi-voltage/frequency battery charger / with interchangeable plugs compatible
with the mote common electrical sockets
•USB cable for PC connection
•Dedicated PC software
•Grinding stone
•Carrying case.
The present manual is valid for units having firmware version 1.22 or higher.

1.4 Intended use and improper use
The Digital Test Hammer 58-C0181 / DGT must be exclusively used for the quality
control of concrete. This method of non-destructive test is not intended as an alternative
to the compression test of concrete for the determination of resistance, but with
appropriate correlations already stored in the instrument, can provide an estimate of the in
situ compressive strength.
The equipment is designed and built to be used by an operator, who must perform the
measurement on the sample to be analyzed in accordance with the instructions provided
in this manual.
The operator is responsible of starting-up the equipment, performing the test sequence,
shutting down the equipment and eventually stopping it in case any emergency conditions
are met.
The operator must be trained on the correct use of the machine and the relative safety
aspects of its use.
The machine should be used following the procedures described in this manual.
Never use the machine for reasons other than those for which it was designed and
manufactured. Any other use of the machine is to be considered improper, not foreseen
and hence dangerous.
CONTROLS will not be responsible for improper use of the machine.

1.5 Safety information
WARNING:
Please read this chapter thoroughly.
CONTROLS designs and builds its devices complying with the related safety
requirements; furthermore it supplies all information necessary for correct use and the
warnings related to use of the equipment.
CONTROLS will not to be held responsible for:
•use of the equipment different than the intended use,
•damages to the unit, to the operator, caused both by installation and maintenance
procedures different than those described in this manual supplied with the unit, and
by wrong operations,
•mechanical and/or electrical modifications performed during and after the
installation, different than those described in this manual
The unit is not designed to be used in an explosive atmosphere.
Installation and any technical intervention must only be performed by qualified
technicians authorized by CONTROLS.
Only authorised personnel can remove the covers and/or have access to the components
under voltage.
During normal use, if the operator detects irregularities or damages, he/she should
immediately inform the authorized technical personnel.
Maintenance and service activities can only be performed by skilled authorized technical
personnel that have been properly trained on the residual risks of the equipment.
It is responsibility of the purchaser to make sure that the operators have been properly
instructed concerning the safety issues and the residual risks related to the equipment.

2.2 Working prenciple
With the new digital rebound hammer 58-C0181/DGT the rebound number is calculated
with an innovative technology taking into account the anvil speed before and after the
impact.
This new working principle is equivalent to the traditional measurement of maximum
spring length after the impact, but it provides the following benefits:
•higher accuracy and stability of the readings not affected by wear and tear
•setting of the impact angle no longer required
•a check of the device reliability can be performed during each impact, even without
the calibration anvil.
Pressing the rod of the hammer against the surface to be examined will charge the spring.
When the rod is completely retracted within the body of the hammer it will automatically
release a mass which strikes the rod in the inner end and, through this, the surface of the
concrete. The harder/more compact is the concrete, the higher the rebound of the mass.
The instrument complies with EN 12504-2 and ASTM C805.
