"Overview" - This is an HMI navigation button which switches the screen back to the Overview.
“Alarming Disabled, Auto Standardization Upper Range Out of Tolerance” – This indicator appears
when an auto standardization upper limit has been exceeded. The operator must perform a manual
calibration of the sensor to clear this condition.
“Auto Standardization Not Perfomed” – This indicator appears when an auto standardization has
never been performed when auto standardization has been factory enabled. The values used in the
correction of gas data are unknown and during this time uncorrected data is presented by the
MultiGard 5000 unit.
4.1.5 Manual Calibration
The Manual Calibration screen is intended for use by the operator during sensor maintenance. It
displays uncorrected sensor readings and gas cylinder flows. It also allows selection of calibration
gases and entry into calibration mode for the purpose of manual sensor calibration. No Auto
standardization occurs while on this screen.
NOTE: If auto standardization has been factory enabled, and after the manual calibration mode has
been entered. Upon leaving the Manual Calibration screen a full auto standardization is triggered
automatically.
NOTE: This screen may be viewed without the auto standardization being triggered upon leaving,
as long as the manual calibration mode was never started. If the “GO TO MAN. CAL. MODE”
button is pressed at any point, an auto standardization WILL be performed.
