Gas Flow
Normal operation of the 3050-DO Analyzer includes an internal bypass, which
increases the response speed of the system; however, the 3050-DO Analyzer is
capable of running in a Gas Saver mode which allows the analyzer to run on a
sample volume of 150 SCCM.
Internal Timing
The analyzer operates in two timing modes. The Normal mode consists of
short intervals of Sample and Reference gas. The Sensor Saver mode reduces
the exposure of the Sensor to the Sample gas by increasing the time spent on
the dry Reference.
If the analyzer detects abnormal degradation of Sensor performance over time
in the Normal mode, the analyzer will automatically switch to Sensor Saver
mode. Once the analyzer switches to Sensor Saver mode, it will not switch
back on its own.
The Sensor Saver mode extends the life of the Sensor, but provides slower
response time. The analyzer updates every 2.5 minutes instead of 1 minute;
however, the analyzer still responds within specications. Refer to analyzer
specications in Chapter 5.
