3. Open sample flow to the analyzer.
4. Apply power to the instrument.
5. Analysis begins automatically when the pyrolyzer and oven reach
operating temperature. If you need to change the configuration, press
any button, and enter the passcode.
Follow these steps to suspend an analysis.
1. Enter the Analyzer Mode top-level menu.
2. Select Suspended to suspend the analysis. In suspended mode, the

Over time, the injection valves begin to wear, resulting in an increased potential
for port-to-port leakage of sample. Such leakage can cause erroneous
measurement and materials buildup in the system. When the analyzer detects
sample leakage through the injection valve, it triggers the Injection Valve
Failure alarm and stops airflow to the pneumatic valves.
Note The Injection Valve Failure alarm must be acknowledged after valve repair
or replacement. ▲
