loop reservoir.
2. Check that the sample fills the fast loop reservoir so that the float switch rises and sample
is being discharged from the overflow drain.
3. Perform an analysis cycle by pressing the RUN Menu and selecting CH 1.
The absorbance detected by the analyzer is used along with the blank and
calibration values to determine a concentration in ppb.
4. When the analyzer has finished the analysis cycle, the concentration reading will be
displayed on the main screen. The result can also be found in the data logger.
5. The analysis returns to standby mode and waits for another user command.
ONLINE MEASUREMENT
6.5
In online mode, the analyzer will run perform consecutive analysis cycles until it is manually
stopped or the out of sample alarm is tripped.
NOTE:
1. Connect the sample tubing to the fast-loop reservoir and turn on sample flow to the fast
loop reservoir.
2. Check that the sample fills the fast loop reservoir so that the float switch rises and sample
is being discharged from the overflow drain.
3. Put the analyzer into online measurement mode by pressing the RUN Menu and selecting
START ON LINE.
The absorbance detected by the analyzer is used along with the blank and
calibration values to determine a concentration in ppb.
4. When the analyzer has finished the analysis cycle, the concentration reading will be
displayed on the main screen. The new result and previous results are stored in the data
logger (up to 500 measurement results).
5. The analyzer will wait the user defined amount of time (see Section 5.7.1) and then
proceed to run additional analysis cycles.
6. To bring the analyzer out of online operation, press the RUN Menu. The top box where
START ONLINE was previously, will now be blank and dark gray. Pressing this box
will tell the analyzer to complete the current analysis cycle and go into stand-by mode at
its completion.
GRAB SAMPLE
6.6
The grab sample feature allows the user to measure the concentration of an external sample.

When starting the analyzer for the first time or restarting it
from any period of shutdown, do not proceed to put the
analyzer into online operation until a calibration has been
performed.
