Distance REF LINE to
highest possible
level 0.000 ft
NEXT↓↓ HELP→→
Defines top of the ROI. If this entry is 0.0, the top of
the ROI is set by the maximum level (or zero distance
point) entry for the primary measurement. A non-zero
entry here overrides the default value for the top of
the ROI, and defines the closest echo processed. The
gauge will not correctly measure above this level.
Minimum value is 2.12 m (0.691 ft).
REF LINE to maximum
distance to be
measured 0.000 ft
NEXT↓↓ HELP→→
Defines bottom of the ROI. If entry is 0.0, the bottom
of the ROI is set by the zero level (or maximum
distance point) entry for the primary measurement. A
non-zero entry here overrides the default value for the
bottom of the ROI, and defines the farthest echo
processed. The gauge will not measure correctly
below this level. Maximum value is 34 m (112 ft).
Slope correction
factor 1.000
NEXT↓↓ HELP→→
Adjust gauge readout using following equations:
Distance = slope factor x (meas. value + offset).
Level = zero level point – distance
Limit slope factor value to range of 0.995 and 1.005.
Consult TN if this value needs to be changed.
Direct Entry Code: ‘049003’
Distance offset
correction
0.000 ft
NEXT↓↓ HELP→→
Offset value for gauge readout adjustment equations
(see entry above). Mounting imperfections can cause
up to 0.10 ft offset error. Limit offset value to range
of 0.0 to 0.16 ft (0.05m). Consult TN if this value
needs to be changed.
