7.2 Analyzer Fault Table

The

Indicators

panel (Figure 7-1) presents a running record of the last 25 check monitoring

operations. If a fault is noted, a red X will be placed on the chart. If the system is presently

reporting that fault, the box in the

Current

column will change from green to red.
