4.1 Introduction
This section provides detailed information required to properly test and calibrate the A7 anesthesia
system. Calibration consists of making mechanical and electrical adjustments with the proper test
equipment. The instrument should be tested and calibrated after repairs have been completed or at
regular intervals as part of a periodic maintenance procedure.
NOTE: Both calibration and a functional test must be performed to verify
complete and proper operation.
Ensure that all testing materials, including drive gas, breathing circuits, test fixtures, tools and
documents are available and current, calibrated and in good working order prior to beginning.
