DESCRIPTION
EvLAB is a complete educational system enabling to carry out all the tests planned for Laboratories of Physics, Chemistry and Biology Sciences. It includes some hardware instruments (Datalogger, sensors, etc…) for gathering data, and some software tools (Data acquisition, spreadsheet, charts, etc…) used for processing and as guide in the tests (Training Software). Both hardware and software tools offer characteristics of potentiality, fl exibility and expansion that make EvLAB an unmatched system on the market.
Datalogger mod. EV2010 has been designed to gather data simply and quickly from laboratory tests.

EVLAB WORKSPACE
Generic data acquisition software that gathers data as function of time. Its layout consist of - an exploration window on the left, where all the available sensors are represented, together with the mathematical, graphical and table processing tools;
- a window at the bottom of the page for messages;
- a window on the right for parameters, with all information on the calibration of instruments;
- superimposable multiple windows in the center, for tools, charts and tables.
This software enables to select the sensors for gathering the data of each test, besides the tables for grouping these data and the charts for their representation. All these data are saved on disk so that they can be retrieved in any moment, without being programmed again. Tests can be carried out in various modes: manual mode, time mode or automatic mode. PHYSICS-EVLABDL-0
Each sensor is equipped with a tool of its own on the screen where the acquired quantities are displayed in real time. Ranges can be modifi ed (where possible) and other parameters concerning measurement can be selected. The spreadsheet enables to gather data automatically in tables. More spreadsheets can be opened at the same time and the quantities having to be inserted in each spreadsheet can be selected. Moreover, some formulae for processing the gathered data and obtaining other quantities can be added in spreadsheets. 3 types of chart can be plotted:
EVLAB WORKSPACE SPECIFIC FOR EACH EXPERIMENTS
For each one of the experiments presented in the Physics, Chemical and Biology catalogues, where the Datalogger and specifi c sensors are required, Elettronica Veneta has designed
specifi c softwares. Each software contains a didactic section, that explains:
AQ-2/EV simulator is part of a new set of educational equipment for the basic training on aircraft systems.
The simulator consists of a computer-assisted panel, with silkscreen mimic diagram for a clear location of its components. Various zones of the mimic diagram are represented with different colours to emphasize peculiar aspects of the system. Light and displays indicators, installed in the mimic diagram enable to assess the evolutions of the control.
The graphic display of the information available at the control input, such as aircraft status (park, APU...) on the computer screen enables the permanent monitoring of the system. The operational conditions are set by students according to the educational path indicated in the courseware, carried out by the PC.

The Hydrostatics and Hydrodynamics laboratory has been designed for hands-on study of the basics of hydrostatics and hydrodynamics. All hands-on labs are conducted on a specially developed test bench equipped with a motion platform, sensors, digital indicators and other components. With the help of this test bench the students can study the law of communicating vessels, floating conditions of bodies, Archimedes’ principle, and study the forces acting on an immersed object depending on its mass and the density of the liquid. The laboratory software has a simple and intuitive User Interface developed in LabVIEW graphical programming environment. The experimental results, along with the student’s registration data, the date and time of the experiment are saved in the system’s database. When connected to an interactive blackboard or a projector the system can also be used for effective demonstrations of the studied principles.
