Spectrum - Sensor and actuator diagnostics
The Spectrum device allows you to test automotive components and verify
their actual operation without using standard self-diagnostics.
Spectrum, the new digital electronic tester for functional testing of
automotive sensors and electromechanical components, is the result of
Microtronics' many years of experience in automotive engineering.
Where self-diagnosis ends, it is essential to trace the root cause of
the problem that generated the error code: thanks to Spectrum, the analysis of
continuous and impulsive (PWM) signals is much simpler than with a traditional
oscilloscope. Spectrum allows you to control electronic or electromechanical
components directly from the original connector and thus immediately verify
their functionality.
