: User programmable for automatic test time and on-demand test of calibration drift test and interference test. Outputs a “PASS” or “ FAIL” on the LCD readout. In the event of fail, user can menu select diagnostics screen to see details on each flow element.
Includes two relay outputs, one changes state while in test mode and the other will change state if any test fails.
Display: (Optional) Large 7 inch [178 mm] color LCD with touch-screen. Provides digital readouts of flow rate, total flow, and temperature with engineering units; bargraph of flow rate and temperature; strip-chart of flow rate which is user programmable for time (minutes, hours, days). Also provides condition status of each sensor, alarm status, results of CEMS test (if so equipped) and user writeable field for process name, tag number, location, etc. User can use touch-screen buttons to access set-up and user programmable features, and diagnostics modes.
Data Logger: On-board extractable MicroSD can store up to 80 million readings. Can log (date + time stamp) any combination of flow rate, totalized flow and temperature with engineering units and will record fault conditions. Data is stored in .csv format for easy uploading into spreadsheets and charts.
