Flush time text box allows you to specify the amount of time to flush the cell prior to
beginning a TOC analysis. You may specify a time in hh:mm:ss format between 00:00:00 and
23:59:59. The default value is 00:01:00.
Cycle time text box allows you to specify the minimum amount of time between automatic
TOC analyses. Any value less than the actual elapsed time causes the next analysis to begin
immediately. You may specify a time in hh:mm:ss format between 00:00:00 and 99:59:59.
The default value is 00:00:00.
Use pump checkbox determines whether or not to use the pump for online sampling. You
may enable or disable this option. If enabled, the analyzer turns the pump on any time water
needs to be drawn from the online water source to the cell. If disabled, the analyzer does not
use the pump for this action. Due to the potential risk of damage to the pump by using it with
a positive pressure water source, enabling this option displays a message asking you to
confirm this choice. The default setting for this option is disabled.
NOTE
Using the sample pump on a pressurized system could damage the pump. Do not use
the pump on a pressurized system.
Bypass flow during analysis checkbox allows you to enable or disable bypass flow.
Bypass flow enables continuous flow of sample water through the analyzer, bypassing the
analysis cell, during TOC analysis. The bypass valve is open when the sample is captured
and closed when the analysis is complete. If enabled, the bypass flow valve opens at the
beginning of the flush. If disabled, this valve remains closed. The default setting is disabled.
