viewable when pressing the function key on the keypad. “FCN 4: Enable” is
a special field with valid values of “On” or “Off.”
Alerts
“Alerts” is a sub-menu allowing access to the “Radiation” and “Integration”
alerts associated with “View 1: R/hr”.
Radiation
“Radiation” is a sub-menu allowing access to the “Enable,” “Value,”
“Multiplier,” and “Units” associated with the radiation alert for View 1.
If the alert is enabled, the instrument will generate an alert message and tone
when the current view radiation rate is equal to the value represented by the
“Value,” “Multiplier,” and “Units” associated with the alert.
Note: The error associated with displaying the radiation rate on the
measurement view is one numerical unit. As a result, an alert value of 20
mR/hr may appear to generate an alert when the radiation rate displayed is
between 19.9 and 20.1 mR/hr; however, the detected radiation rate was 20.0
mR/hr.
Enable
“Enable” represents the ability to enable the radiation alert for the
current view. “Enable” is a special field and valid values include “Off”
and “On.”
Value
“Value” represents the numerical value of the radiation rate alert given
the supplied multiplier and units. “Value” is a numeric field with valid
values from 0 to 999.
Multiplier
“Multiplier” represents the multiplier associated with the radiation rate
alert. “Multiplier” is a special field with valid values of micro, milli, unity,
kilo, and mega.
Units
“Units” represents the units associated with the radiation rate alert.
“Units” is a non-editable field as it must be equal to the units associated
with the current view measurement rate.
