Page 11: Understanding The Controls And Their Operation
Understanding the Controls and their Operation The OMD-501D Trace Oxygen Analyzer is a feature packed unit with an easy to use menu interface. The key attributes within the menu are the ability to select a measurement range, both manually or set it to the auto-range mode. -
Page 12: Measurement Range Overview
Part 3 Operation Measurement Range Overview The OMD-501D Trace Oxygen Analyzer allows the user to field select 5 available ranges - custom ranges are available upon request. These ranges can be selected in manual mode meaning they are locked into that range by the user, or they can be set to auto-range so the analyzer will adjust to give you the best full scale resolution. -
Page 13: Advanced Alarm Functions
Part 3 Operation Advanced Alarm Functions The OMD-501D Trace Oxygen Analyzer is equiped with 2 advanced relay contact alarms. These alarms can be configured as normally open or normally closed, has a delay model built-in and can be enabled or disabled when necessary. Using the color display, the alarms are also color coded. -
Page 14: Analog Output 4 - 20Ma
Part 3 Operation Analog Output 4 - 20mA ** Caution: Integral 4 - 20mA converters are internally powered and do not require ex- ternal power. DO NOT supply any voltage across these terminals as the 4 - 20mA output will be damaged. It is also important to assure proper grounding of the external recording device such as a PLC, DCS prior to connecting the 4 - 20mA. -
