Licensing
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.
Diagnostic Variables 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.
