Factory Calibration

Factory calibration encompasses all aspects of sensor, electronic, mechanical and software tuning to ensure maximum accuracy of all measurements and simulated parameters provided by TTL/PneuView systems.

Calibration procedures include setting of the compliance and resistance characteristics of the lungs (TTL/PneuView) and setting offset and gain characteristics for each of the pressure transducer channels (PneuView only).

Multiple data points are taken at different compliance settings, which are mathematically analyzed and then used to produce an individual Compliance Characteristic Calibration Table (.pvl) for each lung.  It is these calibration tables that the volume calculation algorithms in the PneuView software use to determine the coefficients to use for the real time solution of the dynamic equations (PneuView only).

Calibration Verification by the User

Pressure and Volume calculation accuracy may be easily verified with the aid of a calibrated syringe and independent pressure measurement device.  All versions of the PneuView system ship with pre-formatted templates to aid the user with the verification of calibration accuracy.  These templates include step-by-step instructions, which should be followed periodically to ensure maintenance of calibration accuracy or anytime accuracy comes into question, such as if the unit suffers some type of physical damage.

Recalibration Service

To reduce the potential for an inaccurate reading due to the passage of time or extended use, a recalibration is recommended for your instrument every 2 years for Models 3600i, 5600i & 5601i and every 3 years for models 4600, 1600 & 1601.
