Soil Instruments have designed and developed a powerful data
interpretation software package called ‘In-Profile’ to analyse Digital
Inclinometer System data. If a user chooses to manually reduce the
inclinometer data outside of this software, they should only do so
providing they have full competency. Soil Instruments cannot be held
liable for incorrectly manually reduced data. We offer the following
guidelines to reduce Soil Instruments Digital Inclinometer System data:
DATA REDUCTION VARIABLES
Inc =
Displacement over the probe length
G =
Gauge constant for probe (Metric = 0.01, Imperial = 0.001)
A+ =
Commonly referred to as A0 results. A axis results from first run
in direction of expected movement, leading wheel direction
A- =
Commonly referred to as A180 results. A axis second runs results
180° from direction of expected movement, trailing wheel direction
B+ =
Commonly referred to as B0 results. B axis results from first run in
direction of expected movement, leading wheel direction
B- =
Commonly referred to as B180 results. B axis second runs results
180° from direction of expected movement, trailing wheel direction
DATA REDUCTION TO INCREMENTAL DATA
A axis Inc =
(((A+)-(A-))/2)*G
B axis Inc =
(((B+)-(B-))/2)*G
DATA REDUCTION, ABSOLUTE PROFILE
Accumulate Inc results at each depth to obtain the absolute profile
DATA REDUCTION, CUMULATIVE PROFILE
Subtract the previous absolute profile from the current absolute profile to get the
change in deflection
