Software

The distinguishing features of djb microtech's software are:

  • crisp presentation
  • ease of use
  • on screen support


At the heart of our ALBA data logging software are the dedicated Applications that support learning and teaching throughout the Sciences - from elementary to advanced levels. There are now over 100 Applications and this number is growing. At no time does the user have to enter number of readings, logging interval, trigger levels, channel assignments ... All of this is transparent in our Applications. Step by step instructions support the student throughout their experiment with support for analysis of results and suggestions for addition investigative work. Follow the links below to view sample output.


For users wishing to be in full control of the ALBA Interface then the Investigator software allows them to set the logging interval, number of readings etc. Click to view sample Investigator setup screens.


The ALBA Core software is freely available in the Downloads section. The Core can be used without any hardware and it has all the Table and Graph tools available. Students can download this software at home and use the report writing facilities for presentation of their work.

 

Our current list of software is:

 

Excluding Simple Data Handling all of the above software is for use with The ALBA Interface and Logger. However the ALBA Core software has been adapted to facilitate the operation of the following additional hardware:

  • The ALBA Ranger
  • The Power - Energy - Cost Meter
  • The ALBA Biofermenter Control Unit
  • The A & D electronic balances - EK-i & GF series

Simple Data Handling
Simple Data Handling is a friendly, easy-to-use package that allows you to create attractive graphs, bar charts, pie charts and histograms with a minimum of fuss. With its intuitive interface, Simple Data Handling can be used by all ages. Charts are created and updated automatically to help you understand your data.

Features

  • uncluttered presentation
  • big, easily identifiable icons
  • copy & paste to other packages
  • on-screen instructions and help

ALBA Disk 1
This disk is supplied free with the ALBA Interface and Logger. Most of the files on this disk are freely available when you download the demo version of the ALBA Software.
The Applications on this disk are:

  • A suite of five programs to study capacitor charge and discharge.
  • Evaporation by cooling (requires 2 temperature probes).
  • Cooling curves (requires 2 temperature probes).
  • Two speed of sound experiments (requires a pair of sound switches).
  • Inverse square law for light (requires a linear light sensor).

The manual has several Tutorials that refer to the Applications and sample data files on this disk. A data file accompanies each Application so that those without the ALBA hardware will get a feeling of what can be achieved.

ALBA Disk 2
The Applications on this disk are:

  • Analogue Snapshot - Allows a Table and Graph to be built up one reading at a time. The user enters the independent variable.
  • There are four general purpose Timing Applications:
    1. Fast Timer - Resolution 10 µs with a minimum time of 50 µs.
    2. Gap Timer - Designed primarily for introducing average speed between two light gates but has many other applications.
    3. Event Timer - Displays event times with channel information . Resolution 0.1 ms.
    4. Interval Timer - Used to develop the concept of instantaneous speed.
  • Introduction to Speed - This is a general purpose Application with a user selectable display of time, distance, speed, decimal places and display size.
  • Introduction to Acceleration - This is a general purpose Application with a user selectable display of v1, v2, Delta v, Delta t, acceleration, decimal places and display size.
  • Velocity / Time graph for vehicle accelerating down a slope. The graph is built up point by point.
  • Displacement / Time graph for vehicle accelerating down a slope. The graph is built up point by point.
  • 'g' by Free Fall - a replacement for the 'trap door' experiment. The graph and table are built up point by point.
  • QV relationship.

ALBA Disk 3
The Applications on this disk are all AC experiments:

  • Resistor Current/Voltage - shows that current and voltage are directly proportional for AC.
  • Resistor Current/Frequency - shows that current is independent of frequency.
  • Capacitor Current/Voltage - shows that current and voltage are directly proportional but the gradient of the graph depends on the frequency i.e. frequency is a variable.
  • Capacitor Current/Frequency - shows the direct relationship.
  • Capacitor Current /Capacitance - shows the direct relationship. Combining the three AC Capacitor experiments enables the expression for capacitive reactance to be derived.
  • Inductor Current/Voltage - shows that current and voltage are directly proportional but the gradient of the graph depends on the frequency i.e. frequency is a variable.
  • Inductor Current/Frequency - shows the inverse relationship.
  • Inductor Current/Inductance - shows the inverse relationship. Combining the three AC Inductor experiments enables the expression for inductive reactance to be derived.
  • Series Resonance
  • Parallel Resonance
  • Low-pass Filter - this is intended as an application of capacitors.
  • Bode Plot - this is a general purpose tool for ploting the gain/log(f) of a filter.

It should be noted that some of the Applications on Disk 3 go beyond the Scottish Higher and Advanced Higher syllabus. However it is hoped that the resonance and filter Applications will lend themselves to investigative work.
