Horizontal Linearity: AS 2083—2005
Use V1 calibration block on the 25mm thick side.
Use 4 or 5 echoes for ranges up to 100 mm; use 10 to 20 echoes for 100 mm to 500 mm.Echo Positions (d(n))

Vertical Linearity: AS 2083—2005
Basically, you get the center echo and adjust the gain to reach 10% of FSH, and read the echoe next to it. Then you add gain to reach 20% and read the echo next to it again. Repeat for 30%, 40%, and so on up to 100%.
You can edit both the forced center echo h(n) and the measured next echo h(n+1).
h(n) and h(n+1)
| Point # | Center echo h(n) | Next echo h(n+1) |
