Page 11: Warning Labels
UV Source Lamps Disposal AMETEK recommends that all UV lamps – whether they are new, used, or damaged in any way – need to be disposed of in an environmentally safe manner. Most UV lamps do not contain restricted substances listed under the European RoHS 2 direc- tive.
Page 12: Electromagnetic Compatibility (Emc)
CAUTION The various configurations of the Model 933S Analyzer should not produce, or fall victim to, electromagnetic disturbances as specified in the European Union’s EMC Directive. Strict compli- ance to the EMC Directive requires that certain installation techniques and wiring practices are used to prevent or minimize erratic behavior of the Analyzer or its electronic neighbors.

Page 236: Troubleshooting And Diagnostics
The Model 933S Analyzer has a built-in alarm detection system that continuously monitors the operation of key parameters. An alarm can be detected by either the Host Controller or the Microcontroller and can be of two types: Fault and Warning.
Page 237 A Warning indicates the analyzer may require service and the data may be suspect. Though all Warning alarms cause the Warning Status relay to de- energize, the Warning Status relay can also indicate one of these analyzer operating conditions: • Performing a gas calibration (Auto-Zero, Zero, Span).
