A/B Ratio
A/B ratio calculates the ratio between two one
dimensional measurements. The measurements
supported are:
D
distance
D
circumference (measured by ellipse, trace or two
distance method; for details of circumference
measurements please refer page 105).
The numerator and denominator are such that
A
ńB + Second last measurement
Last measurement
The ratio can be calculated for distance/distance,
circumference/circumference, distance/circumference
and circumference/circumference.
Illustration: Using A/B ratio you can calculate ratio between
femur length (FL) to humerus length (HL) or FL to head
circumference (HC) or HC to abdominal circumference.
Take two one dimensional measurements whose A/B
ratio needs to be calculated (ensure that the numerator is
taken first).
Select 5 in the menu.

A/B ratio is calculated and displayed in the calculation
result area.
A/B measurements should have been made before
selecting A/B ratio. It two measurements have not been
previously made and error message will appear as NM.
