Atmospheric Technology
Upon leaving the manual mode screen, all settings revert to the values used in
automatic mode.
When viewing data in manual mode, the software calibration constants are NOT
a
pplied to the displayed values unless the “Calibrated Values” check box is checked.
When the “Calibrated Values” box is checked, the values displayed have the
corresponding correction constants (i.e slope and intercept) applied and these
values are displayed in red.
4.9 Advanced Mode
Additional settings can be stored in the Advanced Setup section that is accessed
through the
Advanced
tab. This portion of setup should only be used by individuals
familiar with the operation and calibration of components used in the Model 8001.
Changing the values in the Advanced Setup will alter the accuracy of the instrument.
Several of the parameters are hardware dependent. These are set at the factory
and require a password to be entered or changed.
Mass Flow Controller Calibration
The calibration of the mass flow controllers can be changed by entering the
appropriate slope and intercept for each mass flow controller. See Appendix A.
Mass Flow Controller Range (password control)
If the full scale range of a mass flow controller is changed, the corresponding full-
scale range must be entered in the MFC Range box.
Pressure Transducer Calibration
The calibration of the pressure transducers can be changed by entering the
appropriate slope and intercept for each transducer. See Appendix A.
