XMTR variable slot 4
User selected Burst Variable 4.
Local display
The Local Display function on the Rosemount 8600D allows you to select which variables are
shown on the optional (M5) local display. Choose from the following variables:
Primary Variable
Loop Current
Percent of Range
Totalizer
Shedding Frequency
Mass Flow
Velocity Flow
Volumetric Flow
Pulse Output Frequency
Electronics Temperature
Process Temperature (MTA Option Only)
Calculated Process Density (MTA Option Only)
4.3.3 Signal processing
The Rosemount 8600D and its HART-based communications feature enable you to filter out
noise and other frequencies from the transmitter signal. The four user-alterable parameters
associated with the digital signal processing on the Rosemount 8600D include low-pass filter
corner frequency, low-flow cutoff, trigger level, and damping. These four signal conditioning
functions are configured at the factory for optimum filtering over the range of flow for a given
line size and service type (liquid or gas). For most applications, leave these parameters at the
factory settings. Some applications may require adjustment of the signal processing
parameters.
Use signal processing only when recommended in the Troubleshooting section of this manual.
Some of the problems that may require signal processing include:
High output (output saturation)
Erratic output with or without flow present
Incorrect output (with known flow rate)
No output or low output with flow present
Low total (missing pulses)
High total (extra pulses)
