Hi Arking,

Are you using a laser to measure the BL? if so, Are you connecting it to the LB2?
It will be useful if you can send a picture of your setup.

Hi Arking,

I think that you have a wrong laser configuration. The scale should be 10V/m as mention on PPC3.

Hi Figueroa

I am Arking's colleague Bruce, nice to mail to you!

We also use scale 10V/m setting, but the result is still wrong ( it show's "measure out of range" )

And PPC3 also have laser calibration fouction, after calibration PPC3 shows we should use 1V/m setting.

Do we can do anyother test or check ?

Thank you so much!

Best Regards,

Bruce
