METRAwin 10 software
METRAwin 10 software (can be run with DOS or WINDOWS) is
used for the processing and representation of measurement data
at a PC. Sampling in the on-line mode can be performed manu-
ally with an adjustable sampling interval, or dependent upon sig-
nal dynamics (with adjustable signal hysteresis). Storage in the
ASCII format is controlled with two trigger thresholds per mea-
surement channel, as well as with the internal clock.
Data logger (1)
The acquired data is continuously shown on the screen in the
form of a clear table.
Multimeter (2)
Transmitted measurement values from a maximum of 4 freely
selectable channels are digitally displayed at the monitor, and rep-
resented in an analog scale during on-line operation.
Y(t) recorder (3)
The acquired measured values are shown on the screen as time
diagram with horizontal time axis and measured with a cursor.
Stored signals can be zoomed in amplitude and time axis and/or
compressed ("zoom"). The time scale can be presented in abso-
lute time or relative measuring time.
X-Y recorder (4)
The acquired data are shown on the screen on-line as X-Y dia-
gram and measured with the cursor. Same as in all other forms of
presentation, all scales can be freely selected.
Math functions with powerful arithmetics can analyze, link and
display measured data on-line and off-line.
Scanning
Scanning can optionally be performed manually (mouse click),
automatically with selectable interval (50 ms ... 1 min) or signal-
depending with settable signal hysteresis (0 ... 500 digits). The
data can be controlled by time and window trigger and stored
automatically as multiple files.
Data processing
The measured data can further be processed by means of a pow-
erful computer function and by linearization functions.
Thus it is possible, for example, to present mA signals from sen-
sors or transformers directly in print values as active power, and
many more.
Parameterization of the SI232 storage adapters
The storage adapters can be set manually via the front keys or via
the serial interface of the PC. By transmission of the time from the
computer, as many as ten memories can acquire measured val-
ues synchronous with time. Values for minimum and maximum
triggering, recording time and post-trigger time can easily be set.
Also the beginning of the measurement is controlled via the crys-
tal clock of the memory, just as is scanning rate and signal hyster-
esis.
