2 Quick start
Topics covered in this chapter:
• Power up the transmitter
• Check meter status
• Make a startup connection to the transmitter
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1. Ensure that all transmitter and sensor covers and seals are closed.
CAUTION!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
Quick start
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power has been off long enough to allow components to reach ambient
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect
measurement accuracy.
1. Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions. During the power-up sequence, Alert A009 is active.
This alert should clear automatically when the power-up sequence is complete.
2. Check the status LED on the transmitter.

Integrate the meter with the network
4 Integrate the meter with the network
Topics covered in this chapter:
• Assign function block channels to transducer block channels
• Configure AI Linearization
• Configure process alert limits for the AI blocks
• Configure the timeout for Field Diagnostic alerts
4.1 Assign function block channels to transducer
block channels
Fieldbus host AI or AO function block > CHANNEL
AI or AO function block > XD_SCALE (OD Index 10)
AI or AO function block > OUT_SCALE (OD Index 11)
Overview
Each of the four AI function blocks and the AO function block can be assigned to a
transducer block channel. Each transducer block channel is used for a single process
variable. The AI function blocks are used for input data (data sent from the transmitter to
the host). The AO function block is used for output data (data sent from the host to the
transmitter).
Channel assignment for the function blocksFigure 4-1:

Configuration and Use Manual 13
Integrate the meter with the network
Procedure
1. Set the (AI or AO) function block channel to the transducer block channel this block
should report.
2. Make sure the transducer scale is set to the correct units, and change it if necessary.
3. Make sure the output scale units matches the transducer scale units, and change it if
necessary.
4.2 Configure AI Linearization
Fieldbus host AI function block > L_TYPE (OD Index 16)
Overview
AI Linearization is used to rescale a process variable. It can also be used to change the
measurement units. The default setting (Direct) is appropriate for most applications.
Procedure
1. Set AI Linearization as desired.
Option Description
Direct The AI block reports process variables directly from the Measurement trans-
ducer block.
Indirect The value from the Measurement transducer block is rescaled as specified by
the Transducer Scale parameters and the Output Scale parameters. The AI
block reports the inverse of the result.
Indirect
Square Root
Important
AI linearization affects only the process variable reported by the AI block. It has no effect on
the Measurement block. Therefore:
• If you set AI Linearization to Indirect or Indirect Square Root, the process variable reported by the
AI block will be different from the process variable read directly from the Measurement
block. Both the display and ProLink III read data directly from the Measurement block.
• Measurement parameters such as Density Damping and Density Cutoff are processed by the
Measurement block, and the result is passed through AI linearization. Using Ai
linearization to implement damping or cutoff processing may not be possible, and is not
recommended.
The value from the Measurement transducer block is rescaled as specified by
the Transducer Scale parameters and the Output Scale parameters. The AI
block reports the square root of the result. This setting is not applicable to
most Micro Motion meters.
2. If you selected Indirect or Indirect Square Root, set the Transducer Scale and Output
Scale parameters:
14 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus
Integrate the meter with the network
a. Set Transducer Scale: EU at 0% to the value of the process variable when the
transducer block reports 0%.
b. Set Transducer Scale: EU at 100% to the value of the process variable when the
transducer block reports 100%.
c. Set Output Scale: EU at 0% to the value of the process variable when the AI block
reports 0%.
d. Set Output Scale: EU at 100% to the value of the process variable when the AI block
reports 100%.
Specify the two transducer scale parameters in the measurement unit configured
for the transducer block. Specify the two output scale parameters in the
measurement unit configured for the AI block. In most cases, the transducer block
and the AI block use the same measurement unit.
Example: Using scaling to change the measurement unit
The transducer block is configured to measure density in g/cm³. You want the AI block to
report density in oz/in³.
Your lowest expected density value is 0.5 g/cm³. This is equivalent to 0.289 oz/in³.
Your highest expected density value is 0.85 g/cm³. This is equivalent to 0.491 oz/in³.
Set parameters as follows:
• AI Linearization = Indirect
• Transducer Scale: EU at 0% = 0.5
• Transducer Scale: EU at 100% = 0.85
• Output Scale: EU at 0% = 0.289
• Output Scale: EU at 100% = 0.491
Result: As line density varies between 0.5 g/cm³ and 0.85 g/cm³:
• The transducer block varies between 0% and 100%.
• The Measurement block converts this value to a value between 0.5 g/cm³ and
0.85 g/cm³. The result is reported on the display and set to the AI block.
• The AI block applies AI linearization, and reports a value between 0.289 oz/in³ and
0.85 oz/in³.
Configuration and Use Manual 15
Integrate the meter with the network
4.3 Configure process alert limits for the AI blocks
Fieldbus host AI function block > HI_HI_LIM (OD Index 26)
AI function block > HI_HI_PRI (OD Index 25)
AI function block > HI_LIM (OD Index 28)
AI function block > HI_PRI (OD Index 27)
AI function block > LO_LIM (OD Index 30)
AI function block > LO_PRI (OD Index 29)
AI function block > LO_LO_LIM (OD Index 32)
AI function block > LO_LO_PRI (OD Index 31)
AI function block > ALARM_HYS (OD Index 24)
Overview
Process alerts are used to indicate that a process variable is outside the specified limits.
Each AI block has four alert limits: High-High, High, Low, and Low-Low. In general, the
range between High and Low represents the normal process range.
Process alerts are reported only by the affected AI block. They are not shown on the display
or reported by ProLink III.
Prerequisites
Before setting process alert limits, ensure that the four AI blocks are configured for the
appropriate transducer channel (process variable) and measurement unit.
Procedure
1. Select AI Block 1.
2. Set process alert limits:
a. Set the High-High alert to the value of the process variable that will cause the
transmitter to post a High-High alert for this AI block.
b. Set the High alert to the value of the process variable that will cause the
transmitter to post a High alert for this AI block.
c. Set the Low alert to the value of the process variable that will cause the
transmitter to post a Low alert for this AI block.
d. Set the Low-Low alert to the value of the process variable that will cause the
transmitter to post a Low-Low alert for this AI block.
3. For each process alert limit, set the alert priority.
The alert priority is a value between 0 and 15. Higher numbers represent higher
priorities. These values are used for fieldbus network management. They do not
affect transmitter operation: The transmitter will post the alert as soon as the
condition is detected.
4. Repeat for all other AI blocks.
5. Set the alert hysteresis.

Integrate the meter with the network
The alert hysteresis defines a range around the alert limit that operates as a
deadband. The range is defined in terms of % of the output scale. Alert hysteresis is
used to suppress repetitive alerts when the process variable is hovering around the
alert limit.
• A higher value suppresses alerts across a wider range.
• A lower value suppresses alerts across a narrower range. Therefore, alerts may be
posted more frequently.
Important
The alert hysteresis applies to all AI blocks and to all process alert limits.
Example:
AI Block 1 is configured to report line density. The High alert is set at 1.0 g/cm³. The
alert hysteresis is set at 5%.
If line density goes above 1.05 g/cm³, the transmitter posts a High alert. The High
alert remains active until density goes below 0.95 g/cm³.
4.4 Configure the timeout for Field Diagnostic alerts
Fieldbus host DiagnosticsTB > Alert Index (OD Index 017)
Diagnostic TB > Alert timeout (OD Index 083)
Overview
Each Field Diagnostic alert has an individual Timeout parameter. If the alert occurs, it is not
sent to the host until the timeout has expired. Additionally, any associated AI blocks do not
go into fault until the timeout has expired. In other words, the process quality for the AI
block is reported as Good until the timeout expires.
Procedure
1. Set the alert index to the alert you want to configure.
2. Set the timeout as desired:
• Default: 0 seconds
• Range: 0 to 300 seconds

Overview
The calibration factors are used to adjust measurement for the unique traits of the sensor.
Your device was calibrated at the factory. However, you should verify that the calibration
factors that are configured in your device match the factory values.
Prerequisites
You will need the factory values for the calibration factors. These are provided in two
locations:
• The calibration certificate shipped with your meter
• The label inside the transmitter's end-cap
Configuration and Use Manual 19
Configure process measurement
Important
If the transmitter is not the original component, do not use the values from the transmitter label.
Procedure
1. View the calibration factors that are stored in the device.
2. Compare them to the factory values.
• If the values match, no action is required.
• If the values do not match, contact Micro Motion customer service.

5.1.1 Calibration factors
The original calibration factors are obtained from factory calibration, and are unique to
each device. They are used to adjust measurements for the specific physical properties of
the device.
The calibration certificate contains several sets of factors:
Viscosity
calibration
coefficients
Density calibration
coefficients
Temperature
compensation
coefficients
Viscosity
compensation
coefficients
The calibration certificate also provides the results of the Known Density Verification
procedure that was performed at the factory.
For each calibration performed at the factory, the calibration certificate contains the data
used to calculate the calibration coefficients.
Define the relationship between viscosity and the response of your
sensor. Viscosity calibration is performed for one to four viscosity
ranges, depending on the purchase order: Ultra-Low, Low,
Medium, and High. The meter continuously monitors the line
viscosity reading and automatically switches to the appropriate
set of calibration factors.
Define the relationship between density and the response of your
sensor.
Adjust density measurement for the effect of temperature on
sensor response.
Adjust density measurement for the effect of viscosity on sensor
response. There is a set of viscosity compensation coefficients for
the Medium viscosity range, and a set for the High viscosity range.
The viscosity compensation coefficients are generated only if the
corresponding viscosity range is calibrated on your device.

5.2.2 Configure Viscosity Damping

ProLink III Device Tools > Configuration > Process Measurement > Line Viscosity > Line Viscosity Damping
Fieldbus host Not available
Overview
Viscosity Damping controls the amount of damping that will be applied to the line viscosity
value. It affects both dynamic viscosity and kinematic viscosity measurement.
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes
in the process variable. At the end of the interval, the internal value will reflect 63% of the
change in the actual measured value.
Tip
Viscosity damping affects all process variables that are calculated from line viscosity.

Configure process measurement
Procedure
Set Viscosity Damping to the value you want to use.
The default value is 0 seconds. The range is 0 to 440 seconds.
Interaction between Viscosity Damping and Added Damping
When the mA output is configured to report either dynamic viscosity or kinematic
viscosity, both Viscosity Damping and Added Damping are applied to the reported viscosity
value.
Viscosity Damping controls the rate of change in the value of the process variable in
transmitter memory. Added Damping controls the rate of change reported via the mA
output.
If mA Output Process Variable is set to Dynamic Viscosity or Kinematic Viscosity, and both Viscosity
Damping and Added Damping are set to non-zero values, viscosity damping is applied first,
and the added damping calculation is applied to the result of the first calculation. This
value is reported over the mA output.
