Figure 4-4 back fat depth and layers display
The device can measure 1, 2, or 3 layers. the example showed in
figure 4-4 is a 2 layers back fat.
① Layer: One point indicates 1 layer, two points indicates 2 layers,
three points indicates 3 layers back fat.
② back fat depth: The value is the total depth of the back fat.
③ Ruler line: The device measuring range is from 4 to 40mm.
④ Blind area: The single blind area is 4mm. The skin thickness will
not be counted as 1 layer, unless it exceeds 4mm.Most animal skin
thickness is not exceed 4 mm.
⑤⑦ the back fat: There are two layers measured on the image.
⑥⑧ the reflective interface: When the ultrasound meet
different fat layer the reflective signal will be received and the tick mark
is drawn on the ruler line.
