Sphaera's interactive astable/bistable circuit
features a bistable circuit fed by pulses from
an astable circuit through a steering circuit.
The control panel on the left of the screen
features an integrated digital multimeter and 2 oscilloscopes that can
be used to demonstrate or practise methodical fault diagnosis procedures
using voltage checks and resistance checks. Included in the package are
3 faulted circuits.
The digital multimeter and oscilloscopes
also assist in the demonstration or observation of the circuit operation,
as measurements can be taken from any part of the circuit at any time.
The instructor or the student is also provided with the flexibility of
running the simulation in various modes, such as Key Event Mode, which
automatically pauses the simulation whenever events designated as key
