NOTE

When calibrating a transducer always continue uninterrupted to the completion of
that transducer. If several minutes of inactivity occur during a calibration, repeat the
calibration of that transducer as the transducer may drift over time.
For best results, run the ventilator for at least 20 minutes to warm it up prior to
calibration.

Sensing Patient Circuit Mode (FL SENSOR). The patient circuit mode Default Setting
is Flow Sensor. Contact CareFusion or refer to Chapter 12 – Operating Procedure in

the LTV 1100 Operators Manual P/N 21106-001 for detailed information.

Ensure the ventilator is turned on for a minimum of 5 minutes to warm it up prior to
calibration.

If the Main Board was replaced, re-configure the ventilator's configuration settings.
See Configuration section starting on page 6-32 of this chapter for further
details.Check the test fixture manometer for the zero pressure point. There may be a
slight variation in the zero pressure point as a function of barometric pressure and/or
ambient temperature. Adjust the zero point as required to assure that the bottom of
the fluid meniscus is even with the zero line on the scale. (The zero pressure point
adjustement must be made with the manometer disconnected from any pressure
sources and is not to be performed after starting calibration.)
