• What is the precautions when replacing PDL with PGL?

• When connecting the shield of PGL, where should I connect it to?

• Should I install the PGL based on the center of its housing or the center of the laser spot?

• What kind of command is it for PGL setting and reading?

• I think there is sampling of PGL-050W3 / 180W3, normal / high speed mode.
  Is there any difference in how to capture values between normal and high speed? Is it just a difference in time?
  There seemed to be a difference other than time. Please tell me. It is used to detect the end face of a steel rod,
  It seems that he wants to refer to it in the averaging process when there are fluctuations due to heat and variations due to temperature.
