Operation Menu
The Operation menu is used to access the menus and variables that control the processing of the mold level data. It contains
the following items:
ITEM FUNCTION
Filtering Selecting this choice takes the user to the Filtering menu
MLM ch. 1 Filtering Selecting this choice takes the user to the MLM ch. 1 Filtering menu
MLM ch. 2 Filtering Selecting this choice takes the user to the MLM ch. 2 Filtering menu
Detector Fault Selecting this choice takes the user to the Detector Fault menu
Linearization Selecting this choice takes the user to the Linearization menu
Scan Time Shows the amount of time to accumulate each mold level sample and allows the user
to change the time value. This scan time applies to all I/O cards except the MLM
Board
MLM Cycle Shows the amount of time to accumulate each mold level sample and allows the user
to change the time value. This scan time applies to the MLM card which effects the
outputs of the MLM Out 1 and MLM Out 2
Filtering Menu
The Filtering menu is used to configure the parameters associated with the mold level measurement filter, utilizing the
standard scan rate. It contains the following items:
ITEM FUNCTION
Dyn Track Shows the current state of the dynamic tracking filter (enabled or disabled) and allows
the user to change the state
Sigma Shows the (sigma) multiplier used to determine maximum number of raw counts
variation (for scintillation) or raw analog value (for ion chamber) that the input can
vary from the current filtered counts before changing to the dynamic filter. Sigma is
the square root of the current filtered counts. Also allows user to change this number.
Fast TC Fast Time Constant value to be used when the Fast Counter reaches zero
Fast Counter Shows the fast count down counter value. If gage has been in dynamic tracking long
enough to be using Medium filter and the raw counts continued to exceed the sigma
value, the fast counter value is decreased each consecutive scan. The Fast counter
value resets and returns back to the original value if the raw counts do not continue to
exceed the sigma value. Once the Fast TC is triggered, it will continue to be used until
the counts are within the sigma value for the Fast counter number of times
consecutively. Also allows user to change this number
Medium TC Medium Time Constant value to be used when the Slow Counter reaches zero
Slow Counter Shows the slow count down counter value. If gage is in dynamic tracking, and the raw
counts continue to exceed the sigma value, the slow counter value is decreased each
consecutive scan. The Slow counter value resets and returns back to the original value
if the raw counts do not continue to exceed the sigma value. Also allows user to
change this number
Slow TC Slow Time Constant value to be used if the Slow Counter has not reached zero
Noise Filter Shows the maximum number of potentially erroneous measurements in a row to
bridge before deciding that a step change has occurred in the mold level value. Also
allows user to change this number. Erroneous measurement is defined when the raw
signal is 4 times the pre-selected sigma multiplier
Monitor Shows the current state of the filtering mechanism
Monitor (filter state) one of the following:
MONITOR MEANING
TRACK The track will display the current status of the filter whether it is in slow, medium, or
fast mode
