The pdf has a simple exploded diagram.
thank you, Jeff, I did go through the PDF before post the question here, I can not find the answer on the pdf.

it is sealed cases, but can be open-- once turn open the ring case, there is rubber washer/seal between the meter body and the glass panel.
But the face plate with two tiny screws near the center of the triangular needle(picture 1), is where I stopped, I did not want to go further unless I am sure what I am doing.
