The bar graph display shows the current UV or IR signal in counts per
second (cps). The “Display IR / UV” button allows the operator to switch
between the two channels. Two scales are displayed for each channel
— a 1x (times 1) and a 10x (times 10). In normal operation, the UV sig-
nal should be zero and the IR signal should be a low level between 5
and 15 cps. When an automatic Oi (optical integrity) test is in progress,
a small signal level is visible. A small signal is also visible when a man-
ual Oi test is performed, or when a background UV or IR source is
detected.
