Low Alarm:
Low alarm level in CPS, is the point at which the unit will generate a FAULT
condition. Enter a value between 0 and 1,000. The counts from each detector are
compared to this value; if the count from any detector falls below this value the
unit will enter a FAULT mode.
High Alarm:
High alarm level in CPS, is the point at which the unit will generate a FAULT
condition. Enter a value between 500 and 32,000. The counts from each detector
are compared to this value; if the count from any detector exceeds this value the
unit will enter a FAULT mode.
Variance Time:
This menu parameter sets time per variance test, in seconds. Enter a value
between 10 and 100. Refer to Variance (section 3.5.1.) for details.
Number of Trials:
This menu parameter sets the number of iterations for the variance test. Enter a
value between 3 and 10.
Units of Weight:
This menu parameter selects either pounds or kilograms as the unit of weight for
display and report purposes. Minimum weight is always in pounds, and specific
activity is always in pCi/gram regardless of this selection.

This menu parameter enables writing a report to disk. The choice is from three
options: ALL, ALARM, or NONE. Refer to Reports (section 3.6.) for details.
