MLM Ch. 1 & MLM Ch. 2Filtering Menu
The MLM Ch. 1 and MLM Ch. 2 Filtering menu is used to configure the parameters associated with the mold level
measurement filter, utilizing the fast scan rate only. Both contain 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.
Stats The stats display 3 columns: Left = slow; Center = medium; Right = fast. Each column
displays the number of times per second the filter was in the slow, medium and fast
TC
Detector Fault Menu
The Detector Fault menu is used to configure a window in which the detector counts must fall within, in order to
complete a reference/calibration.
ITEM FUNCTION
Min Counts Shows and allows the user to select min count value
Max Counts Shows and allows the user to select max count value
Linearization Menu
The X96S is capable of performing a multi-point linearization of the mold level data when required by an application. The
linearization table contains ten entries, numbered 1 through 32. Each entry consists of a measured value, an actual value, and a
flag that indicates if the entry is used
1 .
The Linearization menu is used to control the linearization mechanism. It contains the following items:
Config Linearize Menu
The Config Linearize menu is used to configure the parameters associated with linearization of the measured data. It
contains the following items:
1 Not all of the entries need to be used and the entries do not need to be used in any particular order.
