The bar graph shows the current UV signal in counts per second (cps).
Two scales are displayed, a blue bar shows the signal level from 0 to
100 cps and a red bar is 10 times the scale (0 to 1000 cps). In normal
operation, the signal should read zero. When an automatic Oi (optical
integrity) test is performed, a small signal level is visible. A signal is also
visible when a manual Oi test is performed or when an external UV
source is detected.

circuitry in the UV detector has detected and isolated a LON wiring
fault.

a manually initiated Oi test.
