increases according to the display mode of the Sensor Controller.
• Profile display: approx. 150 to 300 ms (varies according to profile shape)
• Digital display: approx. 50 ms per displayed task (i.e. approx. 200 ms when four tasks are
displayed)
To set the fastest measurement cycle, use the Sensor Controllers with the display OFF (ECO
monitor).
