STEP6 Thickness measurement
This step explains the basic setting procedures of thickness measurement. The example
below shows the procedures for thickness measurement using two sensor heads.
Set the installation mode to “Diffuse Reflection” and the
measurement mode to “Diffuse Reflection [Standard]”. Refer to
“STEP2 Basic Setting .”
Note that a different installation method is used between specular
reflection and diffuse reflection.
“1-3-2 Sensor Head”
Adjust the position of two sensor heads so their measurement
center come to the same point.
Set Output Selection to –(A+B) to measure the thickness of
measurement object from both sensor heads A and B.
“4-3-2 OUT Setting” – “Output Selection”
· The difference in the measurement value between sensor head A and B, because an
object is extremely different adjacent colors or materials, can be adjusted by setting
Calibration function to each sensor head.
“4-3-1 Head Setting” – “Calibration”
· Use Zero Set function to measure the amount of displacement from the reference thickness.
“4-3-2 OUT Setting” – “Zero Set”
· Select the measurement mode according to the material used for stable measurement.
“4-3-1 Head Setting” – “Measurement Mode”
· Change the sampling cycle and moving average depending on the amount of
displacement and moving speed of measurement object for stable measurement.
“4-3-3 Common Setting” – “Sampling Cycle” and “4-3-2 OUT Setting” –
“Filter Operation”
· When using a reference measurement object, measure the object while Output
Selection is set to -(A+B) and then execute Zero Set. The thickness of the object is
set to Offset. This makes the measurement easier.
