Parameter Description
Recommended Recommended spac‐
space method ing method between
clamp-on sensors for
path X. Calculated on
request.
Clamp-on rec‐ The path the current
ommended recommended spacing
spacing path X values were calculated
for. 0 means not calcu‐
lated since power up.
Clamp-on rec‐ Recommended ideal
ommended spacing distance (LTN)
spacing ideal between clamp-on sen‐
sors for path X. Calcu‐
lated on request.
Recommended Recommended spac‐
spacing ing distance (LTN cor‐
responding to recom‐
mended spacing index)
between clamp-on sen‐
sors for path X. Calcu‐
lated on request.
Recommended Recommended spac‐
spacing (index) ing index between
clamp-on sensors for
path X for the given
spacing method. Calcu‐
lated on request.
Calculate spac‐ Command to calculate
ing recommended spacing
distance, recommen‐
ded spacing method
and recommended
spacing index for a giv‐
en path.
