5.5.1.2 Cycle Time
Note:
Default: 0 minutes
The Cycle Time is user-selectable from 00:00:00 to 99:59:59 (100 hours) and defines the
minimum duration of the analysis. If the Cycle Time exceeds the period required for the
combined sample and oxidation steps, the Anatel A643a defaults to an Idle state until the next
analysis is scheduled to begin. If the specified
Cycle Time is less than the combined sample
and oxidation times, the next analysis begins immediately.
To set the instrument’s Cycle Time :
1) With the Times & Cycle Menu displayed, use the Up and Down Keys to specify
Cycle Time .
2) Press Enter to access its parameter screen. The current Cycle Time is displayed in an
hour:minute:second format, the flashing block cursor highlighting the hour division.
3) Use the Up and Down Keys to specify the time division to be changed.
4) Press Enter to enable the Controller’s Edit Mode and the flashing block becomes an
underscore.
5) Again use the Up and Down Keys to scroll until the desired period is displayed. For
example, if the Cycle Time is set to 00:30:00 , TOC data will be available at 30-minute
intervals. Be sure that the frequency of data reports is appropriate for process
management requirements when determining this interval.
