Analyzer Timing
All Model 888 analyzer functions are broken down into 14 timing periods.
See Logic Table below.
• Periods 1 - 4 are the normal Sample cycle and Zero cycle periods.
• Periods 1 - 11 are fully programmable and are run for a length of time
in seconds.
• Periods 12 - 14 are special “hold” state periods.
Descriptions of events during various timing periods are for typical
operation only. Some events can be altered by changing period timers.
