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.
58-E4800 is used to verify the quality of concrete. It allows the measurement of the
transit time of an ultrasonic wave through concrete products such as beams, columns,
walls, cubes, cylinders and other sample types and to determine the propagation time.
The instrument generates ultrasonic waves which are introduced into the concrete via a
transmitter probe head held in contact with the surface of the concrete under examination.
These waves are read by a receiver probe, held on the concrete face in the same way,
generally on the opposite side of the concrete. The time taken for the wave to travel
through the concrete from one probe to the other is displayed by the instrument.
Piezo-electric probe heads of high and low frequency are available. The first are used to
increase the resolution so as to identify micro-fissures: the second are used to increase the
useful distance between the two heads so as to examine concrete elements of considerable
thickness.
An oscilloscope may be connected to the instrument so as to display the wave form and
identify voids, cracks and other non homogeneous features in the concrete.

1.4 Intended use and improper use
The instrument 58-E4800 should only be used for the quality control of concrete. It
allows the measurement of transit time of ultrasonic waves in concrete elements such as
beams, columns, walls, cubes, cylinders and other sample types and determine the
propagation time.
The instrument is designed to be used by a single operator, who must position the probe
heads correctly on the sample under examination and operate the control/reading unit.
The operator is responsible for switching on the instrument, carrying out the operations
for which the instrument was designed and manufactured, switching off the instrument at
the end of the test or in the case of an emergency.
The operator must be trained on the correct use of the instrument and the relative safety
aspects of its use.
The instrument should be used following the procedures described in this manual.
Never use the instrument for reasons other than those for which it was designed and
manufactured. Any other use of the instrument is to be considered improper, not foreseen
and hence dangerous.
CONTROLS will not be responsible for improper use of the instrument.

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.
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.
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.
During normal use, if the operator detects irregularities or damages, he/she should
immediately inform the authorized technical personnel.
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.

Here follows a list of all WARNINGs present in the manual; please see relevant chapters
for full details on each related safety issue.
WARNING:
We recommend that the user carries out the checks listed in the chapter on maintenance
before each work period. If any anomalies are noted, immediately inform an authorized
technician in merit.
WARNING:
High voltage (at very low Energy) is present in the EMITTER connector of the
instrument, the cable must be connected before switching on the instrument. This voltage
could be dangerous for the user. Also ensure that the cables are not damaged.
WARNING:
Failing to perform the recommended maintenance actions or maintenance performed by
unauthorized people can void the warranty.
CONTROLS will not be responsible for maintenance and service actions performed by
unauthorized people.
WARNING:
Avoid pouring water, even accidentally, or other liquids into the device, as this could
