Effects Of Output At Varied Altitudes; Effects Of Back Pressure; Effects Of Ambient Temperature - GE Tec 6 Plus Operation And Maintenance Manual

Specifications
Effects of output at varied altitudes
Required Dial Setting = Normal Dial Setting % vv x
The Tec 6 Plus Vaporizer is calibrated in percent v/v and the calibra-
tion is not affected by ambient pressure changes. The partial pressure
of the delivered agent at any selected dial setting varies directly with
the changes in ambient air pressure. The required dial setting can be
calculated using the following formula:
760 torr
ambient pressure (torr)
The table below shows the dial setting on a Tec 6 Plus Vaporizer at
altitudes of 1000m and 2000m respectively above sea level:
Effects of ambient temperature
The performance of the Tec 6 Plus Vaporizer is not significantly affect-
ed by the temperature variations within the operating range specified
in Performance.
Effects of back pressure
1107-0641-000 1/23/01
Fluctuating back pressure does not significantly affect the output of the
Tec 6 Plus Vaporizer.
Steady back pressure does not significantly affect the concentration of
the agent delivered (v/v), but does increase partial pressure of the
agent. The increase is in the ratio of total back pressure to the vapor-
izer calibration pressure of 760 torr.
