WP4C 11 TROUBLESHOOTING
5. PROBLEM:
A small triangle appears in the upper right corner after reading:
SOLUTION:
The mirror needs to be cleaned, along with the rest of the sample
chamber, until it disappears. This triangle is a mirror performance
indicator. When the WP4C senses that the mirror performance has
dropped to unacceptable levels, it will display the triangular warning
sign after measuring the sample. When this appears, you should stop
sampling and clean the chamber. If the triangle is still on the screen
after cleaning, the mirror is most likely still dirty and you will need
to clean it until the triangle disappears.
6. PROBLEM:
“Block failure” message appears on screen.
SOLUTION:
• The block is not plugged in to the motherboard. Open the
case and check to make sure that the small ribbon cable that
connects the block to the motherboard is snapped and locked
in place.
• One or more components has failed on the block circuit board.
