tecnotest
new technology
When Tecnotest’s R&D division set out to design our new hydraulic power unit, the objective was to revolutionise the way
compression testing machines work, in that in models built to traditional concepts, a large part of the oil flow produced returns
to the tank without being used.
This poses a serious problem for the machine which must nonetheless compress the oil flow before being separated by a
special device into two branches, one for injection and one for discharge.
Usually by injecting an excessive quantity of oil at a fixed rate, the volume during discharge is decreased and rate of flow is
modulated by means of a valve.
In engineering terms the rational solution would be that of using a pump that generates at any given moment just the right
amount needed for use.
Varying the number of revolutions per minute of the motor would be one approach but still presents some practical problems,
especially given the irreversibility of the pump which is a characteristic which generates substantially asymmetrical responses
during acceleration and deceleration.
To follow a defined load ramp it is necessary to correct the errors which inevitably arise, making negative or positive adjustments
as necessary; the more effective the adjustment, the more accurate the actual line traced compared to the theoretical line.
traditional system
ram

pump
tank
Our idea was to inject very small amounts of oil at a constant rate thus replacing the traditional concept based on a fixed rate
of flow during input and a modulated rate during output with that based on a modulated rate of flow during input and a fixed
rate during output.
In fact the end result is the same, that is to say that of obtaining ramps with negative, nil or positive pace as desired, but with
lower energy consumption.
With such exciting prospects ahead of us, the next step was to design our own, original hydraulic device for use in our own
range of products.

2.1.1
Being of rugged construction, with adjustable draining over a wide range of pressures, the device is not affected by impurities
in the hydraulic fluid so its special feature is that since there is no wear, no maintenance is required.
The range of machines equipped with this device is distinguished by the logo with highlights in particular its noiseless operation
and minimal heat production even during continuous usage.
Use of a variable speed motor with inverter, lamination performed by means of a multi-cylinder pump and the reduction of flow
to pressurize are factors which contribute towards improving substantially energy yield/output.
In order to measure energy saving, we have compared power absorption of the traditional power units with the new, SC series units.
The objective was to reach a load of 2 MN following the pace rate prescribed by Standards for compression testing of concrete
specimens.
Both machines were powered by mains electrical supply (220-240 V, 50 Hz, single phase) so the difference involved the current (A).
As can be seen in the figure, energy consumption in the new series is decidedly lower.

Obviously, the difference in terms of kilowatts and kilocalories is similar.
As for noise, measured using a phonometre in the position occupied by the operator, the difference in the automatic machines
(KP/KE series) is around 10 dB (being reduced from 73 to 63 dB).
In addition to a substantial reduction in energy consumption, an important feature is the excellent response obtained during
adjustments which mean that usage with this range of machines may also be extended to those materials and tests that require
moderate loads.
The device we developed is now patented and installed on all our new line of automatic compression testing machines.

UNE 83304
NF P18-411
HYDRAULIC RAM
BALL SEATING ASSEMBLY
All the compression machines in the range are hydraulic. The
compressive force is generated by a hydraulic ram (50 mm travel)
housed in a rigid, ring-shaped structure.
Safely dimensioned elements in special steel are used to ensure
absolute reliability in all working conditions.
High-precision machine finish reduces frictional forces to a
minimum thus increasing the overall accuracy of the machines.
The ball seat is of the oil bath type, with the exception of KB
series which comply with ASTM only. Ball coupling ensures
initial free alignment with the specimen and subsequent
locking upon specimen contact, as prescribed by BS 1881 DIN 51220 - EN 12390-4.
LOAD FRAMES AND PLATENS
All of our machines are characterized by their high flexural rigidity
on all three axes. This is particularly true of the four column models
but is also a feature of our welded, enbloc frames thanks to the use
of H or tubular section beams which, as is common knowledge,
optimize the stiffness/weight ratio.
The critical point in four-column structures lies in the connections
between uprights and crossbeams; the system adopted by
Tecnotest overcomes the problem arising when the tradition
locknuts are used by using, instead, 32 high-strength screws,
each of which is tightened using a torque wrench so as to
obtain overall pre-tensioning equal to the loading capacity of
the machine.
In this way stability is increased and in line with that obtained by
welding while maintaining optimal structural symmetry.
The test platens are made in compliance with the flatness,
hardness and parallelism criteria of the latest international
standards.
Minimum surface hardness: 550 HV 30 or, upon request 600 HV
(EN 772/1).
A wide range of testing platens for blocks and distance pieces is
available as accessories.
HYDRAULIC POWER UNIT
Automatic and computerized compression machines are actuated
by means of control consoles that use our “Silent & Cold Power”
technology. The semi-automatic machines still use our traditional,
on-board power unit. The latter contains two pumps: a high
capacity/low pressure pump used during fast approach procedure
for securing the specimen is securely fitted between the test platens
and a low capacity/high pressure pump that is used during the
actual testing procedure. This unit is also fitted with two devices
which were specially designed by Tecnotest: a special oil flow
control valve which enables accurate regulation of the load pace
and a valve to allow discharge of pressure and withdrawal of the
ram. The lever-operated, single-acting manual pump has two
different capacities: the higher capacity enables quick clamping
of the specimen between the platens, the lower capacity allows a
reduction in the stress to which the lever is subjected during the test.
Selection is automatically controlled according to pressure exerted.
SAFETY DEVICE
The standard device, fitted on all machines with electronic control
unit consists of two transparent Lexan guards, a safety microswitch
(which allows testing only when the door is closed) and a switch
to prevent overrun of hydraulic ram. Machines fitted with platens
for testing blocks have special guards suitably dimensioned.
Microswitch is not foreseen on manual models or on KB series.
compression testing machines
Developments in the performance of compression testing
machines, reflected in the requirements of major International
Standards, have resulted in machines being produced with greater
stability and alignment criteria. Tecnotest has adopted the policy
of introducing these improvements on its complete range of
compression testing machines.
HOW TO SELECT A TESTING MACHINE
The Tecnotest range comprises machines of 1500, 2000,
3000, 4000 and 5000 kN capacities. Choice of machine is
made according to size and strength of specimens to be
tested in the laboratory. It must nonetheless be underlined
that there is a current tendency to produce concrete with
higher performance so it is a good idea to choose a machine
which has a higher capacity to that indicated by calculations.
Dual ram machines are also available which allow testing with
two different capacities: 2000/300 kN and 3000/300 kN. The
reading system most commonly used nowadays is the digital
readout which has mostly replaced the classic analog dial
gauge, which is still available if requested. Various forms of
data processing become possible through the application of
sensors and electronic control units. Data can be displayed in
numeric form, printed or processed by a computer. In this last
case the fully compiled certificate is obtained automatically.
Computerised models with feedback system and automatic
load pace regulation enable the entire test to be controlled via
the software. As for the structure, the four-column model is to
be preferred for accredited laboratories or research purposes.
testing and CALIBRATION
Each compression machine is tested and calibrated in
compliance with the most advanced standards in force.
In particolar, in countries where EN 12390-4 standard is in
force, control is routine.
All Tecnotest compression testing machines are individually and
accurately calibrated in our laboratory which issues certification
to this effect (with serial number and client’s name).
Upon request, arrangements can be made for indipendent
calibration by an accredited laboratory, authorised to certify
the accuracy and the class of the machines.
Stability testing using four strain gauge, bridge-type tester, to
EN 12390-4 and BS 1881 Part 4, App. A, may be requested.
Tecnotest frames are generously-sized so as to ensure
high rigidity for the two planes of symmetry. This feature, in
conjunction with the ball seating in oil bath, is a pre-requisite
which enables it to pass the stringent tests using the four strain
gauge, bridge-type tester (stability tester or Footemeter).
insurance
Tecnotest has stipulated a civil liability insurance covering damage
to third parties and property caused by our service personnel during
or after installation, verification and maintenance.This insurance
safeguards our customers and their managements interests.

001
This microprocessor-based unit offers a series of auxiliary functions
which make it both practical and easy to use: the initial settings are
menu guided and the way in which pace is displayed during the loading
phase is clearly indicated, while a full range of choices is presented at
the end of the test. There is a graphic display measuring 60 x 32 mm lit
from behind that acts as user interface.
Data is input via a practical numeric key pad and by means of a set of
function keys illustrated on the display. When used with the optional
printer AD 013/B02, the Monotronic allows a hard copy of the test
parameters to be obtained in various languages (Italian, English, French,
Spanish, German, Russian, Polish and Portuguese). Besides the socket
for the transducer, the unit also has a serial port for connection to a printer
or, alternatively, to a PC. The unit has two working modes:

Tecnotest has taken special care as usual to ensure that maximum
readout accuracy of its calibration function is guaranteed.
The calibration function is obviously protected by a password.
Calibration is performed over 11 programmable points from zero
to full scale of the instrument under calibration.
The procedure is particularly simple and designed so that there
is no need for calculation of coefficients, to enter them by hand
or to repeat procedures on a trial and error basis.
In practice, the user is invited to explore the entire readout scale,
then to press a key when the sample dynamometer indicates
exactly 0, 10%, 20%.....90%, 100% relative to full potential of
the machine.
The instruments suggests memorizing 11 points equally
distributed along the readout scale, but these may be modified
as desired : for example, it may be decided to memorize points 0,
1%, 5%, 10%, 20%.....80%, 100% of full scale thus guaranteeing,
thanks to the 500000 divisions available, high precision even at
very low loads. All these operations are extremely simple and
quick to perform thanks to the unit’s function keys and numeric
keypad.
The Eurotronic is one of the few instruments (if not the only
one) in the market to have a numeric keypad for data input.
To enter a number there is no need to call up the number
required by first scrolling up or down using arrow keys, as it is
sufficient to input it via the numeric keypad.

ERROR
FULL SCALE QUOTAS
dual ram
The dual ram testing machine for concrete offers two distinct
measurement scales, with the lower scale covering 10% of the
higher scale.
It is characterized by a hydraulic ram having two concentric stems,
one operating from inside the other but completely autonomous
so that, in practice, there are two machines available in one, the
more powerful machine for specimens of standard strength and
the more sensitive one for testing specimens of lower strength.
A single frame and a single power unit proved an advantageous
solution cost-wise and meant no sacrifices were necessary in
terms of performance when compared with the classic, twomachine solution.
When first presented by TECNOTEST, the project was well in
advance of its time, so much so that only today, after many years,
the dual ram machine is largely recognized as a highly practical
and technologically advanced solution.
The graph on the left shows the theoretical curves that delineate
the possible errors in response made by the two generic devices
with a discrimination of ± 0.1 % of respective full scales.
If a precision higher than 1% is required, the object described
by the red curves, can be used from 10 to 100% of its potential.
The green curves show the effect using the second device which
has the same characteristics but with a scale limited to 10% of
that of the former.
Combining the two objects stretches the field of use to the lower
limit of 1%, so the required precision is respected at all times.

The frame is composed of columns and mono-bloc crossbeams
and uses mechanical connections pre-compressed at nominal
load of machine. Every element is accurately machined to
guarantee the best overall symmetry; its large dimensions
guarantee enhanced rigidity on the three axes. This characteristic,
together with a hydraulic ram incorporating low-friction gaskets
and ball seating in oil bath, ensure that the series complies with
the strictest Standards for precision and stability.
The preset pace rate is actuated by the regulating system
in feedback; further automatic mechanisms ensure that test
procedure is simple and safe.
The control console houses the power pack and the EUROTRONIC
digital display unit (features on page 116), and serves as user
interface and control unit.
The electrohydraulic power pack is of the “Silent & Cold Power”
type, characterised by reduced heat and noise generation, so
this series is suited for all day usage. Pressure is read by an
extensometric type pressure transducer which the EUROTRONIC

These machines are powered by an electro-hydraulic power pack
with a rapid approach pump as standard (low pressure) and a
high pressure pump for testing. General features of frame and
componente are as indicated on page 114.
Dial Gauges (Bourdon type)  are 200 mm diameter with
permissible error ± 1% in upper four fifths of full scale. Parallax
error is eliminated with a strip mirror and a slip pointer is used to
indicate peak load.
On twin gauge machines, a safety maximum pressure valve is
fitted as standard to cut out the secondary gauge once its full
scale has been reached.

These machines (identical to the electric models) differ only in the
hydraulic pump (hand operated). They are ideal for site use where
mains supply is not readily available, for periodical tests and for
basic educational purposes. The manual pump is of the singleaction type with two capacities; high capacity/low pressure for
rapid closure of free clearance between the specimen and upper
test platen, low capacity/high pressure for the application of the
test force. Selection of the high or low capacity is automatically
piloted by the oil pressure.

elastic modulus
ASTM c 469
uni 6556
iso 6784
bs 1881
DIN 1048
In order to determine the elastic modulus of a concrete specimen,
various options are available depending on which of the various
Standards are used as reference and which type of control is
used for the compression machine.
The simplest method is offered by the ASTM C 469 which
prescribes the application of a special mechanical device
(compressometer) to a cylindrical specimen. This device is
equipped with a sensor which measures and amplifies vertical
deformation.
An analog sensor (dial gauge) may be used or, in alternative, an
electronic model (strain bridge type transducer); the former is
used on compression machines that do not have the facility for
automatic data acquisition; the latter requires a computerized
machine equipped with dedicated hardware and software for
the test.
The compressometer may also be equipped with a sensor for
measuring axial deformation (Poisson ratio) and can be supplied
in analog or digital versions.
Where Standards require the measurement of vertical deformation
along more generatrices of the specimen, the instrumentation
used is more complex and the compression machine must be
computerized with feedback.
Two different types of sensors are available: strain gauges for
affixing directly on the specimen, and physical transducers,
supported by mechanical strain gauges which must be applied
using elastic bands. Obviously the former may be used once
and then discarded; the latter may be used over and over again.
Hardware and software installed in the computerized compression
testing machine change according to which type of sensor is used,
so at time of ordering the system in its entirety must be taken
into examination. For automatic machines with EUROTRONIC
software may be added as and when required. There are four
readout channels for deformation, but more may be added upon
request.
Various Standards regulate the test procedure: UNI 6556,
BS 1881:121, DIN 1048, so it is a good idea to specify which
upon ordering so as to enable the relevant software modules that
automate the test to be installed.
software for data processing and
management via pc in real time
AD 050/B68
Hardware and software to expand upon the already wide
range of testing and measurement possibilities available using
EUROTRONIC readout unit/digital display installed on semiautomatic (KD series) and automatic (KE series) machines.
The system enables elastic modulus and Poisson ratio to be
measured using various types of sensors in accordance with the
various international Standards. In practice it is now possible
for the EUROTRONIC to dialogue with a remote PC in which to
concentrate all the complex input and output operations by means
of dedicated software that operates in Microsoft Windows XP and
newer Windows operating environments. For obvious reasons
computerization is extended to all the standard test routines.
At any time during the test the graph may be shown in real time.

electro-hydraulic power units
The forces required for destructive tests on concrete specimens are such that hydraulic actuators need to be used that are
capable of operating safely with pressure of hydraulic fluid reaching around 700 bar.
To generate a flow of oil at such pressures, the power unit must be fitted with special components that only a limited number
of manufacturers are able to supply. If, as in our case, a particularly accurate rate of flow is required, the range of commercial
valves available is reduced practically to nil and so we had to resort to designing our own. In all our electro-hydraulic power units,
highly accurate control is made possible thanks to components built specially to our design.
In our semi-automatic machines, in which load pace is regulated via a hand-wheel, the hydraulic valve maintains a constant flow
of oil to the actuator independently from the pressure, so there is no need for the operator to have to make continual adjustments
in order to follow the load ramp prescribed by Standards.
In our automatic and computerized machines, regulation is controlled electronically by the feedback system; the closed-loop
control is based on the number of rotations of the motor, so the rate of hydraulic flow varies accordingly.
The unique feature of Tecnotest’s valve is its ability to release a small amount of oil at a constant rate so as to reduce the load
developed by the ram when discharge exceeds the capacity of the pump.
Differently from other systems, the motor continues its rotation even when the feedback system requires a reduction in load; in
this way it is possible to optimize the course of the programmed ramp and avert the typical step-like progression.
A particularly important feature of this innovative technology is that it results in a reduction of energy consumption, a lower oil
temperature and reduced noise.

Specially designed to satisfy demands of major laboratories having large amounts of standard samples to be tested and thus
requiring optimum efficiency. Equipped with high precision, state-of-the-art electronic and mechanical components, this model
is undoubtedly the most advanced compression testing unit ever manufactured anywhere in the world.
Testing time is reduced to the absolute minimum necessary for compressing the sample until failure load is reached.
This model has the same features as the automatic, computerised machine with feedback system and four column frame (pag.
134 - 135), but weighing and measuring of 15 and 20 cm/side samples is also automatic.
WEIGHING is carried out by means of an electronic cell whereas MEASUREMENT of sides is carried out by a LASER BEAM and
height by an OPTICAL MEASURING DEVICE: the data are stored automatically via the management software.
A CONVEYOR BELT facilitates sample movement before the test. Accurate positioning of sample on the tester is obtained by means
of a specially-designed HYDRAULIC POSITIONER (15 and 20 cm/side) which also discharges previously broken sample on to the
bench top and simultaneously cleans test platen; a second HYDRAULIC ARM pushes the broken samples along the bench top.
Tests on samples different from 15 and 20 cm/side are carried out automatically, even if the load cell, the laser beam and the
hydraulic positioner are not activated.
Automatic load pacer and transferral of compression and strain data to PC. Obviously, a hard copy of certificates for stored tests
may be obtained via the ink-jet printer.
The PC controls three different operations simultaneously:
- data input for one sample
- measuring and weighing of a second sample.
- compression and strain data acquisition and control for a third sample.
Optimal productivity, after verification, is approx. 500 samples in 8 hours for 15 x 15 cm or 20 x 20 cm samples.
- 25 N/mm2 specific strength - with 50 N/cm2/s load pace.

The structure has four columns connected to two monobloc crossbeams. The assembly is made by means of a special mechanism
allowing connections to be pre-tensioned to 3000 kN. The result is a particularly rigid frame suitable for both routine and
experimental tests. Height of the spacious compression testing bay may be modified by means of the distance pieces required
for testing specimens of different dimensions to be positioned quickly and effortlessly. The loading ram works at pressure lower
than 300 bar, that is to say half that of the standard 3000 kN compression machines, which is an advantage when it comes to user
safety and life-span of components. The hydraulic power unit is designed for continuous use and is equipped with an air-oil heat
exchanger with thermostat. Automatic regulations can be by-passed so that the user can perform particularly accurate regulations,
such as those required for calibration purposes, using a hand-operated valve. The software provided with the machine comprises
a program for compression testing at constant load pace as well as that for multiple cycle tests intended for providing loading/
unloading ramps and programmable stops on demand. Additional software modules are available for other tests such as flexural
testing and modulus of elasticity measurement.

The complete machine may be configured according to customer’s
requirements and based on sizes of pipes to be tested.
STEEL FRAMES
Customers usually prefer to have the frames designed and built
in steel (or a combination of steel and concrete) structural work
locally, so as to avoid the high costs involved for freight and
assembly.
Tecnotest supplies all the components for load application as well
as control console.
We can nonetheless supply a steel frame for testing pipes having
diameters from 450 to 1500 mm.
Shaped bearers for all pipe diameters, necessary for eventual
flexural tests, are excluded.
Kn steel frame
P 460/70
Steel frame for compression tests (700 kN) on concrete
pipes (dia. 450 to 1500 mm). To be used in conjunction with
our loading systems P 445/70 and P 445/72. Complete with
2-speed electric winch for lifting intermediate cross beam, two
lower (supporting) bearers 2500 mm long and one upper bearer
(floating type) 2500 mm, for compression tests.
Hot galvanization of complete structure. Highly rigid base.
Dimensions: 2620 x 2500 x 5060 (h) mm. Weight: 3800 kg.
The frame is delivered disassembled.

ELECTRO-HYDRAULIC LOADING SYSTEM
Our loading systems can be used for any mechanical structure
designed and built by the customer according to their specific
requirements. Capacities available: 700 kN and 1000 kN.
The system comprises a digital display unit (MONOTRONIC or
EUROTRONIC) for load readout and electronic load cell for load
measurement. LOAD BEARERS AND STEEL FRAME ARE NOT
INCLUDED.

The complete system comprises:
- Hydraulic power pack housed in a cabinet.
Load pace controlled. Contains two pumps, one high
capacity/low pressure and one low capacity/high pressure.
Once the specimen comes into contact with the upper platen,
the first pump is automatically excluded. The hydraulic power
unit is completed by a maximum pressure safety valve, a
decompression valve and a special oil flow control valve which
allows the accurate control of oil flow thus allowing precise
operator control of load pace. These valves were specially
designed by Tecnotest to assure required linearity and smooth
operation.
Power supply: 220V – 50 Hz – single phase.
Cabinet dimensions: 700 x 530 x 1050 (h) mm.

5000/600 kN Machine for Calibrating Load Cells (compression) L 500
This compression machine has been designed in order to be able to apply a range of loads with minimum manual regulation
thus enabling high capacity extensometric load cells to be calibrated (in compression) placing sample dynamometers on top for
reference purposes.
The frame comprises 4 columns connected to the two cross-beams by means of four special, highly-resistant screws which have
been tightened using a torque wrench so as to pretension to 5000 kN with the result that the frame stability remains excellent
no matter what loads are applied.
The cross-beams are entirely in machine-tooled, monobloc steel while the 200 mm diameter columns are in chrome-plated high
resistance special calibrated steel.
Assembly tolerance is greater than 0.05 mm and rigidity is around 2 · 10 – 4
Based on an exclusive Tecnotest design, the machine has two hydraulic rams: a 5000 kN ram and a 600 kN ram sunk into the
former so as to effectively allow two work scales.
Maximum working pressure is 400 bar.
A special device, combined with the flow valve, enables load to be regulated during both upward and downward movement along
with no movement at all when load is constant.
A maximum pressure valve located on the control panel allows load limit to be pre-set at any value.
Vertical span can be easily changed from between 500 and 1000 mm (by 25 mm intervals) thanks to a distance platen loading
device that runs along tracks.
In fact, a hydraulic jack controlled via the console clamps the selected platens in packs then centres them.
The hydro-electric control panel (with two speeds: rapid and test speeds), the electrical panel, the cooling system, the controls
and check gauge are all housed in a separate console.
The machine is supplied with neither ball seating nor with sample dynamometer which, if needed, should be ordered separately.
Load cells, having different classes of accuracy are available, as well as universal digital control units which may be certified
(official SIT certification) page 393.

Micro-core samples are extremely useful for verifying structures
especially since their extraction does not cause any damage due
to the dimensions of the holes (which, in any case, can be filled
with mortar).
The test is easily performed and only requires the presence of one
operator. The drilling jig, the self-blocking pincers and the bit guide
device all contribute to guarantee correct and accurate sampling.
The equipment is water-cooled and the tank is pressurised via
a foot pump.
The equipment comprises:
- 2 speed electric hammer-drill (220 V, single phase)
- Bit guide device
- Water tank with foot pump
- 2 impregnated diamond bits, 28 mm (inner dia.), 35 mm
(outer dia.) with different lengths for 100 and 200 mm
cores.
- 2 self-blocking pincers for securing the guide device
- Series of blocks, screws, bits and wrenches for use with

hardware and software for

The Monotronic digital readout unit is available in another version,
the Geotronic (AD 200), supplied with a “current loop” interface,
instead of the usual RS 232 serial port. Even if it is easy to transfer
current data to a computer via the RS 232, the number of serial
ports on the PC is limited in that a PC with Windows environment
may normally be connected to a maximum of 2 Monotronic units,
this being the number of serial ports effectively available.
With the Geotronic version the limit is higher provided the
Multiplexer AD 021/010, which enables a network of peripherals
to be controlled by a single RS 232, is used.
Such a device enables:
a) quick scanning (5 readings/second) with a network comprising
(maximum) 3 Geotronic units and for a maximum duration of 999
seconds;
b) slow scanning (with a minimum of 1 reading every 2 seconds)
with a network comprising up to 32 Geotronic units and a
maximum of 99 times.
In this last version, each Geotronic unit stores the data in its own
memory. The computer therefore is activated only at the start
of the test phase and when reading or transferral of peripheral
files is required. In any case an ASCII data file is created with
measurements referring to period of time elapsed. The file can be
opened and processed with Windows software (Word, Excel...).

To create a local area network, the following are required:
- AD 021/012 electric cable, supplied in 10 m lengths,
complete with connections.
- Connector blocks, to be selected from among the
following:
AD 021/001 one-way connector block
AD 021/002 two-way connector block
AD 021/003 three-way connector block
AD 021/004 four-way connector block
AD 021/010 Multiplexer
- The only really essential components are, in practice, the
PC (unless one is already available), the MULTIPLEXER for
connection to NETWORK (AD 021/010), the CABLE (AD
021/012) and DATA ACQUISITION SOFTWARE. All that need
be added are the connector block or blocks as appropriate for
the number of Geotronic units to be used.
- The AD 021/010 MULTIPLEXER enables between 1 and 32
channels to be activated by simply connecting other Geotronic
units and relevant connector blocks.
- . Although its initial function is to INPUT and load the Geotronic
units, afterwards it may be either turned off or used for a
different purpose. When switched on again, a chart showing
data acquired so far may be called up on the video screen to
check progress or to conclude test and store results on disk.
- Each measurement is displayed on the Geotronic unit on
board the apparatus in engineering units as taken, thereby
eliminating the need to interrogate the computer in order to
observe progress of the test.
- : hence problems arising in any given Geotronic risk
jeopardising functions of the relevant channel only while the rest
of the laboratory remains unaffected.
