3. SIGNAL ANALYZER
The Signal Analyzer (refer to Section V) also assists the user in diagnosing
failures. The analyzer can record eight parameters over a specified time period,
which is useful in detecting machine or system problems. For example, speed
feedback can be recorded to detect a bad gear tooth or out of balance roll. Refer
to Section V for setup and operation of the signal analyzer.
