Circuit Calibration Concepts
The Trilogy Evo Universal is optimized for circuits that are within the specifications shown in the Circuit section of the Accessories chapter. If you
want to use a different circuit, you can perform an optional Circuit Calibration, intended to characterize compliance and resistance. The circuit
calibration process includes the following procedures, based on the type of prescription:
Depending on the circuit type:
•
Active circuits: calibrates according to the results of the leak test, compliance, and resistance
•
Passive circuits: calibrates according to the compliance and resistance
When you start the circuit calibration, follow the instructions on the screen as the system completes the tests.
If the calibration is successful, then you will see a confirmation message.
If the circuit fails any part of the test, the reason appears in the window. Adjust the circuit and repeat the calibration. If you repeat the calibration
but the circuit still fails, you can either replace the circuit and try again or you can use the default settings.
Information about the circuit calibration is recorded in the Event Log. For more information about the Event Log, see “Alarm and Event Log” in the
“Alarms” chapter.
