This software has been developed for my school-leaving examination
in 1995. It is a program that simulates a system for checking magneto-thermic
switches. There's a data acquisition procedure that sets the value
for the current of the circuit and measures the intervention time.
You can chose beteen three types of switch: U, K and L. It's also
possible to create a visual graph of the characteristic of the switch,
with graphs I-t or I-I2t.
