Uncompromising performances in the laboratory or on-site

A new standard in metrological

performance and accuracy

Efficient by design: enhanced

handling for ease of use

On its launch, the ASYC2 range from Metrix® established a new
standard in metrological performance, both for its high-perfor­mance specifications and its entirely new "virtual adjustment"
functions, representing a breakthrough in field instrument techno­logy.
The latest ASYC3 range (MTX 3281, MTX 3282 and MTX 3283)
continues this tradition of innovation, with top of the range hand­held multimeters offering a resolution of 100,000 counts, a basic
precision of 0.02% and a 200 kHz pass band: performance and
precision that sets them apart from the competition.
Innovative features and performances that are user-managed
thanks to the optional calibration software, making periodical
checks faster, easier and more economical.

Their unique design, featuring a multidirectional screen and elec­tronic control switch, makes this range of instruments ideally
suited for both tabletop and hand-held use.
The power supply system is equally innovative, offering all the
benefits of a modern instrument, while combining a rechargeable
accumulator for on-site use, and a mains adapter that also func­tions as a charger for the laboratory.
Thanks to this dual mains supply system, recordings over longer
periods are no longer vulnerable to untimely power outages on the
instrument.

Compact and robust when not in use, the ASYC3 range's "variable
geometry" design provides enhanced handling and ergonomics
when opened out, thanks to its simple lines and extra-slim casing.
Its "one-hand one-touch" design enables the instrument to be held
and operated by the same hand: measurement functions are
selected by simply pressing on the appropriate key of the elec­tronic control switch.
In addition, a specially designed hands-free carrying pouch leaves
the user free to operate the required lead connections, avoiding
the need for cumbersome fittings and accessories.

For optimal efficiency and safety, the instrument proposes only 3
measurement terminals.
When the mobile lead is connected to the Ampere or Volt terminal,
the corresponding function is automatically selected in AC+DC
mode, complete with auto-ranging, thus reducing handling and
operating to a minimum.
Its fully moulded casing, both self-extinguishing and extra-resis­tant, offers IP51 protection rating.

Uncompromising performances in the laboratory or on-site

Display features not usually

found on this type of instrument

For greater reading comfort, the series features an extra large
multidirectional backlit screen offering multiple display functions
and analogue bargraph. About the neck, on a tabletop, or in the
hand: whatever the position, the display remains visible.

A "preferred measurement" key allows the user to
programme automatic access to their most frequently used
measurement mode.
Whatever the physical quantity measured, this key enables you to
convert the scale and define the appropriate measurement unit, so
as to obtain direct readings of the original quantity.

Thanks to technological improvements resulting in a single “A”
terminal, current measurements may be carried out from a single
switch position, making for fluid and trouble-free changes of the
measurement range, from just a few hundred microamperes to up
to 20 amperes.
Current and voltage measurements may even be carried out simul­taneously, using 3 measurement leads, and the corresponding
result "V x A" displayed.

The only instrument of its kind
equipped with an electronic
control switch that replaces
traditional mechanical swit­ches (the primary cause of
malfunctions on conventional
hand-held multimeters), the
ASYC3 range offers at the
same time improved perfor­mances and safety
features. Direct acces one­touch controls remove the
need for the intermediate positions
found on conventional mechanical control switches.
The principal measurement modes are instantly accessible using
the instrument's 6 direct-access keys, making it no longer neces­sary to choose between the 4 or 5 positions required by conven­tional mechanical switches in order to carry out simple voltage or
current measurements.

Selected modes and functions, as
well as physical and electrical
values, and relevant warning
symbols, are all clearly displayed
on the instrument's160 x 160 high­resolution graphic display.

Depending on the function
selected, results are displayed in
either mixed digital/graphic or in
uniquely digital mode

Features 4 digital displays, for the
simultaneous reading of
measurements requiring a
minimum number of operations
(combination of measurements:
SPEC, REL, MEM, SURV).

In mixed display mode, the digital
display offers stable and accurate
measurement readings, while rapid
variations are clearly indicated by
the bargraph. A 3rd dimension is
added thanks to the instrument's
graphic recorder, enabling you to
display measurement variations
over time.

All operating menus and help
windows are available in 2
languages (English and French).

Technology

in the service of safety

Lead/command coherence is fully managed by the multimeter,
which upon detecting a lead present on the Ampere or Volt termi­nals, automatically selects the corresponding function.
When a lead is connected to the Volt terminal, for example, the
instrument automatically proposes to check for the presence of
voltage before carrying out resistance or capacitance measure­ments.
On the practical side, the Ampere input's single HRC fuse has
made it possible to reconcile the instrument's compact design
with the increased safety distances required by compliance with
IEC standards 61010 1000 V / CAT. III, 600 V / CAT. IV.
An innovation that also represents an effective safeguard against
wiring errors, liable to destroy the safety fuses normally used for
current measurements.

The battery and fuse compartment has been designed for greater
protection, providing secured access that requires leads to be
disconnected before opening.

Innovative functions for all-round

measurement performance

Thanks to its MATH function, the ASYC3 series is particularly
suited to the measurement of different physical units. This allows
the user, whether measuring
physical quantities in Volts,
Amperes, Hertz or Ohms, to
convert the quantity and
assign the appropriate unit
to it, in order to obtain a
direct reading on the
secondary display unit of
the original quantity.
This type of function may
be assigned directly to the
"Favourite measurement"
key, in which case it is
carried out automatically.

Thanks to the instrument's 4

digital displays, the relative

function REL provides

comprehensive simultaneous

display of the absolute and

absolute drift values, relative

drift % and reference value.

For greater comfort, the refe-

rence value can be adjusted

directly using the REL func-

tion key.

Other standard features include control of the attenuation and the
bandwidth on electronic circuits.
The dB function on the ASYC3 series enables you to display all the
information you need directly, including voltage, frequency, and
attenuation in dB, with respect to reference values.

Total measurement control

Thanks to its innovative AUTOPEAK mode, changes of current
and voltage ranges are now based on the rapid acquisition of
peaks, in order to avoid untimely overruns of the instrument's Peak
Factor, liable to result in measurement errors without the user
being aware of it. Except for the instrument's 1000 V range, this
removes the need for limitation of the peak factor.

Another innovative feature is

the instrument's SPEC func-

tion, which automatically

displays measurement tole-

rances without the user

needing to calculate it.

The user is thus in complete

control of the measurement

uncertainties, whatever the

range and the AC signal

frequency.

Uncompromising performances in the laboratory or on-site

Enhanced features and

performance for error-free fault

detection

Universal

communication technology

The ASYC3 series, offering the combined features of both a multi­meter and a recorder, is the perfect all-round diagnostics tool for
your maintenance, adjustment or development needs, on-site or in
the laboratory.
Whatever your electronics applications, be they in the domain of
processes, production equipment or energy distribution, the

ASYC3 series ensures a cutting-edge difference.

The ASYC3 series' graphic

recorder display offers a

3rd dimension in measure-

ment performance, provi-

ding you with at-a-glance

graphic display of measure-

ment variations over time.

In addition, its SURV function
enables you to display and
record simultaneously the

minimum, maximum and

average values of a given

measurement, as well as the

date/time recording of limit

and beginning and end

values, for the period moni-

tored.

The MEM function enables
you to record up to 6500

date/time measurements,

for periods ranging from 1
sec to 24 hrs, and to

analyse the results graphi­cally for up to 4 simulta-

neous measurements.

Thanks to its PC-compatible analysis software, measurement
results may be exported in real-time or deferred mode, enabling
you to store, analyse, document and transfer data to a standard
spreadsheet programme.

The measurement of individual or periodical rapid peaks of 250 µs,
using the instrument's PEAK function, makes it possible to
pinpoint anomalies that are normally undetectable using conven­tional multimeters, and to carry out first-hand diagnosis of signal
types based on the Peak Factor displayed.

Thanks to optically insulated RS232 and USB ports, and inte­grated Bluetooth technology, the ASYC3 series provides you with
universal communication that is adapted to all working environ­ments.
Metrix® offers you an expanding range of customer services,
including a user "hot-line":[e-mail], software
update services, enabling you to upgrade your firm-ware versions
