NAME

       Galvani -  a program for plotting and evaluating measurement data

SYNOPSIS

       galvani [options]

DESCRIPTION

       Galvani  reads  measurement  data of digital multimeters from a serial interface. Data are
       plotted graphically in a diagram. Two channels are available, therefore 2 devices  can  be
       used in parallel.

       Several mathematical transformations are available for data evaluation:
       • Inverse (1/x)
       • Logarithm
       •  Conversion  of  a  Copper/Constantan-  or  Nickel/Chromnickel-thermocouple  voltage  to
       temperature difference
       • Conversion of timeline to volumina (for titrations)

       There are some mathematical operations available for evaluation of graphs:
       • Differential function
       • Integration of peak area in Chromatograms including tabulation
       • Linear regression of data

       Diagrams can be exported into several file formats (PNG, SVG, EPS) or printed as report.

       Additionally, measurement data can be  simulated  (in combination with  random  variables)
       as:
       • Linear function
       • Exponential function (decay curve)
       • Chromatogram
       • Titration curve

SETTINGS

       The  appearance of diagrams can be controlled in several options. Data points can be shown
       as cross, circle, square or diamond and/or can be interpolated by lines or curves.

       All settings for serial communication with the device can be  saved  as  files.  For  some
       devices,  there  exist  already configuration files from which settings can be read. Also,
       setting measurement function remotely is possible if the device has this option.

FILES

       $(HOME)/galvani
           Device specific settings are saved as files in this folder.

       $(HOME)/galvani/data
           This folder contains the data files (.dat) produced  by  galvani  and  graphical  data
           (.png,  .svg, .eps) exported by the program. Alternatively other folders can be chosen
           for saving data files.

       $(HOME)/.galvani
           In this hidden folder galvani saves  the  file  galvani.ini  holding  information  for
           autoloading and autosaving program settings and the configuration file galvani.conf in
           which all program settings are saved and can be read at program start.

       /tmp/galvani
           Folder for temporary files.
