Receiving Window

1.

Set the measurement area to SAV using your

software.

Memo

• This will cause the lens to move closer to the

receiving window, making it easier to clean.

2.

Use a blower to remove dirt and dust from the

receiving window.

{

Do not put your fingers into the receiving window or
touch any optical lenses.
