General
Applications
UNIGOR 380 and UNIGOR 390 multimeters are high performance
precision instruments for the lab, service and training. With a display
range of 310,000 digits as well high level accuracy and longterm
stability, they fulfill all calibration and R&D laboratory demands.
Battery operation allows for on-site precision servicing and calibration.
Description
Convenient Triple Display
The current measurement value, as well as two other values, are
updated and displayed, e.g. minimum and maximum value. The
usual switching back and forth between display values is no longer
necessary. Display resolution for the main display value can be
varied from 4 ¾ digits for AC to 5 ¾ digits for DC (UNIGOR 390:
from 2 ¾ to 5 ¾ digits). The measurement rate, adjustable from 0.5
ms to 10 s, allows for high-speed recorder, precision data logger
and mean value recorder functions with the help of UNIGOR Win
300 (PC software).
High Resolution and Precision
5¾ digits, or 309,999 digits, allow for cost effective calibration and
precise reference measurements.
Effective Value for Distorted Waveforms
The implemented measurement process provides for effective value
measurement (TRMS) independent of the waveform up to 100 kHz.
AUTO SELECT
Provides for automatic selection of the measurement function (V, Ω
and F), as well as automatic setting of the measuring range.
Additional Functions
Continuity testing with audible signal, event counting, event duration
measurement, overall time, stopwatch, data compare and widerange capacitance measurement. The integrated temperature
measurement function allows the connection of thermocouples and
platinum resistance thermometers.
Overload Protection
The instrument is protected from overload in the voltage range.
Acoustic signalling occurs if measuring range limits are exceeded.
The FUSE display indicates a defective fuse in the current range.
Calibration
UNIGOR 380 and UNIGOR 390 multimeters are shipped with a
calibration certificate. They can be automatically calibrated with a
calibration system via the RS232 data interface.
Power Pack and Sensor Connection
The connector terminal for power supply via mains power pack can
be used alternately for multimeter power supply or for the output of
pressure sensor auxiliary power (accessory for UNIGOR 390).
Automatic Blocking System (ABS)
Automatic Blocking of connector Sockets prevents incorrect
connection of measurement cables, and selection of incorrect
measurement magnitudes. Thus hazards for the operator, the
instrument and the system are substantially reduced, and in many
cases entirely eliminated.
Autom. Measurement Value Storage
The DATA HOLD function allows for storage of the digitally
displayed measurement value. A patented process assures that the
actual measurement values are stored when rapid measurement
magnitude changes occur. The stored measurement value appears
at the digital display.
Infrared Measurement Data Transmission
These devices include a serial, duplex data interface for remote
control and measurement value transmission via infrared light.

The following functions are available for data reduction:
• Trigger when lower/upper threshold limits are exceeded
• Trigger within lower/upper threshold limits
• Store when lower/upper threshold limits are exceeded
• Store within lower/upper threshold limits
The trigger function can also be triggered by date and time. An
“automatic restart” function allows for the storage of up to 1000 trigger
data files to the PC hard disc.
Multiple Measurement System Set-Up
(on-line and off-line)
Up to 6 UNIGOR mem 232 adapters can be interconnected for the
set-up of an on-line, high performance multiple measuring system,
which are connected to a PC with a standard interface cable
(RS232C), or up to ten adapters for off-line operation. Each adapter
can be manually equipped with a specific destination address.
UNIGOR link 232 Interface Adapter
With the help of the UNIGOR link 232 bidirectional adapter,
UNIGOR 380 and UNIGOR 390 multimeters can be adjusted and
their para-meters can be set, and measurement data can be
transmitted to the PC. This adapter includes no memory.

Adapter for the connection of the multimeter to a PC
Whereas the UNIGOR 380 can be expanded with the
UNIGOR mem 232 memory adapter for memory mode operation and
connection to the PC, the UNIGOR 390 includes an integrated
memory and only requires an interface adapter for PC connection.
Both devices can be connected to the PC with either UNIGOR mem
232 or UNIGOR link 232 adapters.
UNIGOR mem 232 Memory Adapter
The UNIGOR mem 232 memory adapter, which can be plugged on
to hand-held UNIGOR multimeters, provides for direct transmission
of measurement data from a UNIGOR to the PC, as well as on-site
measurement data storage without PC, and subsequent uploading to
the PC. Data are synchronized with an integrated clock.
Memory: 128 kB (equal to about 100,000 measurement values)
Interface Packs
An interface pack is capable of connecting one or more UNIGOR
multimeters to a PC. It includes all hardware and software required for
the set-up of a PC measuring system.

Sampling
With a selected sampling rate of max. 0.05 s, an arithmetic mean
value is ascertained for measurement values which are transmitted at a
clock pulse of 50 ms. Within a range of 1 s to 60 s, the signal sampling
duration remains at a constant 0.5 s (10 measurement values). Thanks
to the integrated stand-by circuit, the memory module enters the
“dormant mode” for the remaining duration of the sampling cycle after
acquirement has occurred, and thus spares the battery. Signal
acquirement is thus interrupted during the rest cycle. The functional
principal is the same as for a dot matrix printer. Sampling is based on
the selected signal hysteresis, and is signal-dependent.
This sampling method results in a virtual memory expansion, which is
independent of measurement signal dynamics and selected signal
hysteresis.
This allows for a manifold expansion of memory capacity (10-...100-fold).

Trigger (on-line)
The on-line trigger functions are quite varied and enable effective data
reduction. They are triggered when lower or upper limit threshold values
are exceeded.
4 UNIGOR digital multimeters, connected to one another via
UNIGOR mem 232 memory adapters, result in a multiple measuring
system in combination with a PC and UNIGOR Win 300 software.
The measurement values are electrically isolated with the fully enclosed
UNIGOR housing, and are transmitted via infrared light to the
UNIGOR link 232 interface adapter or UNIGOR mem 232 memory
adapter. Connection to the PC is made with a serial interface cable.

UNIGOR Win 300
Measurement Data Processing


UNIGOR Win 300 software (operative under WINDOWS 3.11 or
higher) provides for the processing and representation of measurement
data at the PC. Sampling in the on-line mode can be accomplished
manually with the adjustable sampling interval, or signal dependent
(with adjustable signal hysteresis). Storage in ASCII format is controlled
with two trigger thresholds per channel, as well as via system time.
Measurement data can be analyzed, linked and represented, on or
off-line, by means of high performance computing functions.
(1)
Further processing of measurement data is also possible with
linearisation functions. mA signals from sensors can thus, for
example, be directly represented as pressure values, apparent power
etc.
(2)
UNIGOR mem 232 Memory Adapter Parameters
Memory adapter parameters can be set manually with the keys at the
front panel, or via the PC serial interface. If synchronized with the PC
clock function, up to ten memory adapters can be used for
synchronous data logging. Values for minimum and maximum value
triggering, recording time and re-trigger time can be easily adjusted.
Start of measurement is also controlled with the quartz movement
integrated into the memory adapter, as well as sampling rate and
signal hysteresis.

Data Logger (1)
Acquired measurement data from as many as 10 channels are
numerically represented at the monitor in concise tabular form.
Multimeter (2)
Transmitted measurement data from a maximum of 4 freely
selectable channels are represented at the monitor in the on-line
mode in digital or analog form.
Y(t) Recorder (3)
Acquired measurement data from up to 4 freely selectable channels
are represented at the monitor as a line graph with horizontal time
axis, and are delineated with pointers. Stored signals can be
expanded (zoom) or compressed, relative to amplitude as well as
time axis. The time scale can be represented in absolute time, or
relative to measuring time.
XY Recorder
Acquired measurement data from two to four freely selectable
channels are represented at the monitor as an XY graph, and are
delineated with the cursor. As is the case in all display formats, all
scales are freely adjustable.
Sampling (on-line)
On-line sampling is accomplished manually (mouse click),
automatically with an adjustable interval (50 ms ... 60 min) or
signaldependent with adjustable signal hysteresis (0 ... 500 digits).
Data can be controlled with timing or trigger windows, and
automatically stored as multiple data files.
