temperature or strain gradient, reducing the Gauge Length to a lower value may
produce a more stable result.
Note
The Spatial Resolution filter (in the Data Processing
area) does not apply to distributed sensing measurements.
Instead, spatial resolution for distributed sensing
measurements is controlled by the Gauge Length setting
in the Data Processing area. To achieve the accuracies
listed in the Specifications Sheet shipped with your
instrument, set the Gauge Length to 2 cm.
