Sampling with pressure

CAUTION
Potential burst hazard! Do not exceed the maximum 100 psi (690k Pa) sample pressure
ratings.
NOTE
Using the sample pump on a pressurized system could damage the pump. Do not use
the sample pump on a pressurized system.
In online TOC mode, the cell valve opens to flush the cell.
• When flushing is completed, the cell's sample valve closes, the analysis begins, and
• When oxidation is complete, the analyzer reports the results to the home screen, the

Sampling from a zero pressure system

If you are sampling from a zero pressure system, you can enable the pump option to draw
water into the cell. For instructions on setting up the pump option, see TOC,

Conductivity is monitored until oxidation is complete.
data log, and the printer, based on the printer settings and if the printer is connected.
The analyzer then checks to see if the elapsed time is greater than or equal to the
value for cycle time in settings. If it is, the next online TOC analysis is started.
Otherwise, the analyzer enters the idle mode.
