17. Calibration Procedure for V4.3.1 & V4.3.2 software
The calibration procedure is to be used in-conjunction with a checklist. The
checklist is used to record the calibration values set during the procedure. This
checklist will be become part of the service record of the ventilator. A template
checklist (which should be copied) is to be found in Appendix 1 of this manual on
page 305.
Where information needs to be recorded the user will see symbol next to
the section.
Note: Prior to calibration enter ENGMODE and record the following Gain /
Offset values. This will allow you to revert the ventilator back to it pre-
calibrated state if required.
Gain and Offset for the 1 PSI and 2.5 PSI pressure transducers.
Gain, HFO Offset and CMV Offset for the Forward jet.
Gain and CMV Offset for the Mean jet.
Gain, HFO Offset and CMV Offset for the Reverse jet.
Insp leading Edge Fast / Slow rise time and F/S Balance.
Exp leading Edge Fast / Slow rise time and F/S Balance.
Use the table of pre-calibration constants in Appendix 1.
17.1 Equipment required for calibration.
1. A calibrated flow analyser.
2. N9025 calibration kit.
