Level 2 Config Menu (Go To); Timers (Measurement Cycle Timers); Default Memory (Reset To Factory Default); Coef_D (Polynomial Coefficient D) - Ametek 5000 Instrument Manual

Level 2 Config Menu (Go to Level 2 Configure Menu)
When is pressed with this menu item selected, the Level 2 Configure Menu is accessed im-
ENTER
mediately. Because the Level 3 password cannot be altered from the factory default, this is useful to
access Level 2 functions if the Level 2 password has been changed or forgotten.

Timers (Measurement Cycle Timers)

!
Changing these timers will affect the curve fit function used by the analyzer. Please consult AM-
ETEK service before changing these timers.
CAUTION

Coef_D (Polynomial Coefficient D)

For low concentration applications (<1 ppm), the constant Coefficient D is used to correct for the
offset between the sample and reference gases caused by the two gases being subjected to different
outgassing mechanisms. Refer to Appendix C: Determination of Offset and Coefficient D Adjust-
ment for more information on the setup and procedure used to determine Coefficient D for each
sample point. Coefficients PolyCoef_D1 through D4 correspond to the offset between sample points
1 through 4 and the reference gas. PolyCoef_D5 is used for special applications only and is normally
set to zero.
Press CANCEL to roll through the variables PolyCoef_DX where X=1
ficient value when the "New Value?" prompt is displayed. Press ENTER to save change and display
the next coefficient; press CANCEL to quit.
Default Memory (Reset Controller to Factory Default Values)
Select this menu item to reset all system configuration parameters to factory default values. Press
to reset; press
ENTER CANCEL
!
Before resetting the controller to default configuration, it is advisable to
CAUTION
record current configuration values by selecting View Configuration from the
Page 3-14: Test/Config Main Menu.

Items marked with an asterisk (*) on the configuration data sheet supplied with the analyzer vary
from system to system and are determined during the factory calibration of the instrument. When
NOTE
system is reset to default values, these items must be entered manually in order to duplicate the
original configuration of the specific analyzer.
