measurement time (*2) or averaging times, distance
range and sampling resolution)
Sensor optical fiber settings (optical fiber length, wave
number, group index, loss correction, temperature offset
correction and winding coefficient (distance-depth
conversion factor))

Data
processing
functions
Temperature data
calculation
Calculates temperature by applying various defined
corrections.
Generated data
Temperature distribution data, temperature alarm data
and sectional temperature data
Sectional temperature data
generation (up to 200
sections can be defined)
Data generation sections can be defined with the
temperature output data type (average, maximum,
minimum, difference or slope) selected for each section
Detection
functions
Temperature alarm settings
(Up to 20 alarm sections
can be defined)
Alarm detection sections can be defined with
temperature high limit, low limit, rise limit, fall limit and
difference limit, average temperature difference high
limit, average temperature difference low limit values
specified for each section.
Optical fiber failure
detection
An error and alarm is generated if optical fiber loss
exceeds a specified threshold value.
Increased loss detection
An increased loss alarm is generated if the CFL value
near the fiber far end exceeds a threshold value.
Data
management
functions
Configuration data Various settings
