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.
8714i Results
Review the results of the 8714i Meter Verification tests. For more details on
these results and what they mean, see Appendix C: Diagnostics.
Test Condition
Displays the conditions that the 8714i Meter Verification test was performed
under. For more details on this parameter see Appendix C: Diagnostics.
Test Criteria
Displays the criteria that the 8714i Meter Verification test was performed
against. For more details on this parameter see Appendix C: Diagnostics.
