Licensing

Diagnostic Variables

If a diagnostic suite was not ordered initially, advanced diagnostics can be licensed in the field. Access the licensing information from this menu. For more details on licensing, see Appendix C: Diagnostics.

License Status

Determine if a diagnostics suite has been licensed, and if so, which diagnostics are available for activation.

License Key

A license key is required to activate diagnostics in the field if the diagnostic suite was not initially ordered. This menu allows for gathering of necessary data to generate a license key and also the ability to enter the license key once it has been received.

Device ID

This function displays the Device ID and Software Revision for the transmitter. Both of these pieces of information are required to generate a license key.

License Key

Allows you to enter a license key to activate a diagnostic suite.

From this menu, all of the diagnostic variable values can be reviewed. This information can be used to get more information about the transmitter, sensor, and process, or to get more detail about an alert that may have activated.

Empty Pipe Value

Read the current value of the Empty Pipe parameter. This value will read zero if Empty Pipe is turned off.

Electronics Temperature

Read the current value of the Electronics Temperature.

Line Noise

Read the current value of the amplitude of AC line noise measured on the transmitter’s electrode inputs. This value is used in the grounding / wiring diagnostic.

5Hz SNR

Read the current value of the signal to noise ratio at 5 Hz. For optimum performance, a value greater than 100 is preferred. Values less than 25 will cause the High Process Noise alert to activate.

37Hz SNR

Read the current value of the signal to noise ratio at 37.5 Hz. For optimum performance, a value greater than 100 is preferred. Values less than 25 will cause the High Process Noise alert to activate.

Signal Power

Read the current value of the velocity of the fluid through the sensor. Higher velocities result in greater signal power.
