Troubleshooting
Checking Alignment of the UV and Visible Images
The UV image (corona) and the visible object on which corona is generated should
remain aligned throughout the LCD display and their relative position should be kept
whether in the center or off center. Or else, consult the manufacturer.
Focus
If the camera needs to be recalibrated, ask the manufacturer for the procedure to be
performed by the camera operator.
To check alignment of the UV and visible displays: Use a candle behind a screen with a
pinhole. Place a camera, set on auto focus, at a distance of about 12m from the screen.
The UV and visible images of the pinhole should superpose whether their image is in
the center or in the extreme left or right sides.
