98 DF-310E Troubleshooting and Calibration
3) If it is not practical to remove the Analyzer from the sample delivery system, leaks can be
located by monitoring Analyzer output while applying Snoop® or another liquid leak detector to
one fitting at a time. Snoop® will not show bubbles at the low pressure required for proper
Analyzer operation. However, Snoop® will temporarily block any leak, at the fitting being
checked, and the Analyzer output will drop. It is important to give sufficient time for the
Analyzer to respond before going on to the next fitting.
The more distance between the fitting and the Analyzer, the more time should be given for the
Analyzer to respond.
