17-D.Enable or Disable Continuous Mode using the CHANGE CHOICE key. If Continuous Mode is enabled the program will continuously run and switch bottle sets after every specified duration elapses, until manually stopped. If Continuous Mode is disabled, then the sampling halts when the last bottle set in the tray is full.

17-E.Press ACCEPT to continue to Upset Sample.

Step 18 - Upset Sample

Note: Unlike Setpoint Sampling, Upset Sampling can be enabled while the sampler is performing its regular sampling program. There must be more than one bottle in the sampler to perform Upset Sampling.

Upset Sampling analyzes the collected samples to determine when samples meet or exceed specified upset limits. The sampler will swing the distributor arm around to a sequestered set of bottles and grab an upset bottle.

The upset sample bottles are always the last bottles in the tray. For example, if there are 24 bottles in the tray, 4 first flush bottles and 4 upset bottles, then the bottles assignment is 1–4 first flush, 5–20 main program, and 21–24

upset samples.

Upset Samples are collected even when there are no more regular samples to be taken; when the status screen says Program Complete, but the bottom line of the display says Program Running.

Refer to the Quick Start Guides on page 103 for more setup information for individual channels.
