Topics covered in this chapter:
• Power up the transmitter
• Check flowmeter status
• Make a startup connection to the transmitter
• Characterize the flowmeter (if required)
• Verify mass flow measurement
• Verify the zero
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
Ensure that all transmitter and sensor covers and seals are closed.
1.
Quick start
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.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alarm 009 is active. The diagnostic routines should complete in approximately
30 seconds. For transmitters with a display, the status LED will turn green and begin
to flash when the startup diagnostics are complete. If the status LED exhibits
different behavior, an alarm condition is present.
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 is 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 flowmeter status
Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.
Configuration and Use Manual 7
Page 16
Quick start
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, Alarm A009 is active.
This alarm should clear automatically when the power-up sequence is complete.
2.
Check the status LED on the transmitter.

Overview
Characterizing the flowmeter adjusts your transmitter to match the unique traits of the
sensor it is paired with. The characterization parameters (also called calibration
parameters) describe the sensor’s sensitivity to flow, density, and temperature.
Depending on your sensor type, different parameters are required. Values for your sensor
are provided by Micro Motion on the sensor tag or the calibration certificate.
Offline Maintain > Configuration > Calibrate Sensor
• ProLink > Configuration > Flow
• ProLink > Configuration > Density
• ProLink > Configuration > T Series
Tip
If your flowmeter was ordered as a unit, it has already been characterized at the factory. However,
you should still verify the characterization parameters.
Procedure
1.
Specify Sensor Type.
• Straight-tube (T-Series)
(5)
• Curved-tube (all sensors except T-Series)
2. Set the flow characterization parameters. Be sure to include all decimal points.
• For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and
(5)
FFQ.
• For curved-tube sensors, set Flow Cal (Flow Calibration Factor).
3. Set the density characterization parameters.
• For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2.
(5)
• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown
as DT.)
(5) Devices with the Chinese-language display do not support T-Series sensors.

2.4.2 Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4character FT value. They are provided on the sensor tag.
Both values contain decimal points. During characterization, these may be entered as two
values or as a single 10-character string. The 10-character string is called either Flowcal or
FCF.
If your sensor tag shows the FCF and the FT values separately and you need to enter a
single value, concatenate the two values to form the single parameter value.
If your sensor tag shows a concatenated Flowcal or FCF value and you need to enter the FCF
and the FT values separately, split the concatenated value:
• FCF = The first 6 characters, including the decimal point
• FT = The last 4 characters, including the decimal point

Example: Concatenating FCF and FT
FCF = x.xxxx
FT = y.yy
Flow calibration parameter: x.xxxxy.yy
Example: Splitting the concatenated Flowcal or FCF value
Flow calibration parameter: x.xxxxy.yy
FCF = x.xxxx
FT = y.yy
2.4.3 Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
Density calibration parameters are typically on the sensor tag and the calibration
certificate.
If your sensor tag does not show a D1 or D2 value:
• For D1, enter the Dens A or D1 value from the calibration certificate. This value is the
line-condition density of the low-density calibration fluid. Micro Motion uses air. If
you cannot find a Dens A or D1 value, enter 0.001 g/cm3.
• For D2, enter the Dens B or D2 value from the calibration certificate. This value is the
line-condition density of the high-density calibration fluid. Micro Motion uses water.
If you cannot find a Dens B or D2 value, enter 0.998 g/cm3.
If your sensor tag does not show a K1 or K2 value:
• For K1, enter the first 5 digits of the density calibration factor. In the sample tag, this
value is shown as 12500.
• For K2, enter the second 5 digits of the density calibration factor. In the sample tag,
this value is shown as 14286.
If your sensor does not show an FD value, contact Micro Motion customer service.
If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density
calibration factor. In the sample tag, this value is shown as 4.44.
2.5 Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use
any available method.
• Read the value for Mass Flow Rate on the transmitter display.
• Connect to the transmitter with ProLink II and read the value for Mass Flow Rate in the
Process Variables window (ProLink > Process Variables).
• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in
the Process Variables panel.
Configuration and Use Manual 13
Page 22
Quick start
• Connect to the transmitter with the Field Communicator and read the value for Mass
Flow Rate in the Process Variables menu (On-Line Menu > Overview > Primary Purpose
Variables).
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues. See
Section 12.3.
2.6 Verify the zero
Verifying the zero helps you determine if the stored zero value is appropriate to your
installation, or if a field zero can improve measurement accuracy.
The zero verification procedure analyzes the Live Zero value under conditions of zero flow,
and compares it to the Zero Stability range for the sensor. If the average Live Zero value is
within a reasonable range, the zero value stored in the transmitter is valid. Performing a
field calibration will not improve measurement accuracy.
2.6.1 Verify the zero using ProLink II
Verifying the zero helps you determine if the stored zero value is appropriate to your
installation, or if a field zero can improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless
one of the following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Prerequisites
ProLink II v2.94 or later
Important
Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem,
then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a lowseverity alarm is active.
Procedure
1.
Prepare the flowmeter:
a. Allow the flowmeter to warm up for at least 20 minutes after applying power.
14 Micro Motion® Model 2700 Transmitters with Analog Outputs
Page 23
Quick start
b. Run the process fluid through the sensor until the sensor temperature reaches
the normal process operating temperature.
c.
Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
d. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
2. Choose ProLink > Calibration > Zero Verification and Calibration > Verify Zero and wait until
the procedure completes.
3. If the zero verification procedure fails:
a. Confirm that the sensor is completely blocked in, that flow has stopped, and that
the sensor is completely full of process fluid.
b. Verify that the process fluid is not flashing or condensing, and that it does not
contain particles that can settle out.
c. Repeat the zero verification procedure.
d. If it fails again, zero the flowmeter.
For instructions on zeroing the flowmeter, see Zero the flowmeter.
Postrequisites
Restore normal flow through the sensor by opening the valves.
2.6.2 Verify the zero using ProLink III
Verifying the zero helps you determine if the stored zero value is appropriate to your
installation, or if a field zero can improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless
one of the following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Prerequisites
ProLink III v1.0 with Patch Build 31, or a later release
Important
Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem,
then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a lowseverity alarm is active.

2.6.3 Terminology used with zero verification and zero
calibration
Terminology used with zero verification and zero calibrationTable 2-2:
Term Definition
Zero In general, the offset required to synchronize the left pickoff and the right pickoff under
conditions of zero flow. Unit = microseconds.
Factory Zero The zero value obtained at the factory, under laboratory conditions.
Field Zero The zero value obtained by performing a zero calibration outside the factory.
Prior Zero The zero value stored in the transmitter at the time a field zero calibration is begun. May
be the factory zero or a previous field zero.
Manual Zero The zero value stored in the transmitter, typically obtained from a zero calibration proce-
dure. It may also be configured manually. Also called “mechanical zero” or “stored zero.”
Live Zero The real-time bidirectional mass flow rate with no flow damping or mass flow cutoff ap-
plied. An adaptive damping value is applied only when the mass flow rate changes dramatically over a very short interval. Unit = configured mass flow measurement unit.
Zero Stability A laboratory-derived value used to calculate the expected accuracy for a sensor. Under
laboratory conditions at zero flow, the average flow rate is expected to fall within the
range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model
has a unique Zero Stability value. Statistically, 95% of all data points should fall within the
range defined by the Zero Stability value.
Zero Calibration The procedure used to determine the zero value.

Overview
A special measurement unit is a user-defined unit of measure that allows you to report
process data, totalizer data, and inventory data in a unit that is not available in the
transmitter. A special measurement unit is calculated from an existing measurement unit
using a conversion factor.
Note
Although you cannot define a special measurement unit using the display (standard option), you can
use the standard display to select an existing special measurement unit, and to view process data
using the special measurement unit.

ProLink II ProLink > Configuration > Flow > Flow Damp
ProLink III Device Tools > Configuration > Process Measurement > Flow
Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping
Offline Maintain > Configuration > Damping > Mass Flow Damping
Overview
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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
The default value is 0.8 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table.
Core processor type Update Rate setting Flow Damping range
Standard Normal 0 to 51.2 seconds
Special 0 to 10.24 seconds
Enhanced Not applicable 0 to 51.2 seconds
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• The combination of a high damping value and rapid, large changes in flow rate can result in
increased measurement error.
28 Micro Motion® Model 2700 Transmitters with Analog Outputs
Page 37
Configure process measurement
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
• For gas applications, Micro Motion recommends setting Flow Damping to 2.56 or higher.
The value you enter is automatically rounded down to the nearest valid value. Valid
damping values are shown in the following table.
Valid values for Flow DampingTable 4-2:
Core processor type Update Rate setting Valid damping values
Standard Normal 0, 0.2, 0.4, 0.8, ... 51.2
Special 0, 0.04, 0.08, 0.16, ... 10.24
Enhanced Not applicable 0, 0.2, 0.4, 0.8, ... 51.2
Effect of Flow Damping on volume measurement
Flow Damping affects volume measurement for liquid volume data. Flow Damping also affects
volume measurement for gas standard volume data. The transmitter calculates volume
data from the damped mass flow data.
Interaction between Flow Damping and Added Damping
In some circumstances, both Flow Damping and Added Damping are applied to the reported
mass flow value.
Flow Damping controls the rate of change in flow process variables. Added Damping controls
the rate of change reported via the mA output. If mA Output Process Variable is set to Mass
Flow Rate, and both Flow Damping and Added Damping are set to non-zero values, flow
damping is applied first, and the added damping calculation is applied to the result of the
first calculation.

The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the
factory. The recommended setting is 0.05% of the sensor's rated maximum flow rate or a
value below the highest expected flow rate. Do not set Mass Flow Cutoff to 0.0 g/sec.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from the
actual mass data rather than the reported value.
Interaction between Mass Flow Cutoff and AO Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as
measured. AO Cutoff defines the lowest flow rate that will be reported via the mA output. If
mA Output Process Variable is set to Mass Flow Rate, the mass flow rate reported via the mA
output is controlled by the higher of the two cutoff values.
Mass Flow Cutoff affects all reported values and values used in other transmitter behavior
(e.g., events defined on mass flow).
AO Cutoff affects only mass flow values reported via the mA output.
Example: Cutoff interaction with AO Cutoff lower than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• AO Cutoff: 10 g/sec
• Mass Flow Cutoff: 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0
will be used in all internal processing.
Example: Cutoff interaction with AO Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• AO Cutoff: 15 g/sec
• Mass Flow Cutoff: 10 g/sec
Result:

• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
- The mA output will report zero flow.
- The frequency output will report the actual flow rate, and the actual flow rate will
be used in all internal processing.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0
will be used in all internal processing.

• ProLink > Configuration > Density > Slug Low Limit
• ProLink > Configuration > Density > Slug Duration
• Configure > Manual Setup > Measurements > Density > Slug High Limit
• Configure > Manual Setup > Measurements > Density > Slug Duration
Procedure
1.
Set Slug Low Limit to the lowest density value that is considered normal in your
process.
Values below this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the lowest density value in the normal range of your
process.
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of slug flow alarms that are not significant to your process, set Slug Low Limit
slightly below your expected lowest process density.
You must enter Slug Low Limit in g/cm3, even if you configured another unit for
density measurement.
The default value for Slug Low Limit is 0.0 g/cm3. The range is 0.0 to 10.0 g/cm3.
2.
Set Slug High Limit to the highest density value that is considered normal in your
process.
50 Micro Motion® Model 2700 Transmitters with Analog Outputs
Page 59
Configure process measurement
Values above this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the highest density value in the normal range of your
process.
Tip
To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug
High Limit slightly above your expected highest process density.
You must enter Slug High Limit in g/cm3, even if you configured another unit for
density measurement.
The default value for Slug High Limit is 5.0 g/cm3. The range is 0.0 to 10.0 g/cm3.
3.
Set Slug Duration to the number of seconds that the transmitter will wait for a slug
flow condition to clear before performing the configured slug flow action.
The default value for Slug Duration is 0.0 seconds. The range is 0.0 to 60.0 seconds.
Slug flow detection and reporting
Slug flow is typically used as an indicator of two-phase flow (gas in a liquid process or liquid
in a gas process). Two-phase flow can cause a variety of process control issues. By
configuring the slug flow parameters appropriately for your application, you can detect
process conditions that require correction.
Tip
To decrease the occurrence of slug flow alarms, lower Slug Low Limit or raise Slug High Limit.
A slug flow condition occurs whenever the measured density goes below Slug Low Limit or
above Slug High Limit. If this occurs:
• A slug flow alarm is posted to the active alarm log.
• All outputs that are configured to represent flow rate hold their last “pre-slug flow”
value for the configured Slug Duration.
If the slug flow condition clears before Slug Duration expires:
• Outputs that represent flow rate revert to reporting actual flow.
• The slug flow alarm is deactivated, but remains in the active alarm log until it is
acknowledged.
If the slug flow condition does not clear before Slug Duration expires, the outputs that
represent flow rate report a flow rate of 0.
If Slug Duration is set to 0.0 seconds, the outputs that represent flow rate will report a flow
rate of 0 as soon as slug flow is detected.

ProLink II ProLink > Configuration > Density > Density Damping
ProLink III Device Tools > Configuration > Process Measurement > Density
Field Communicator Configure > Manual Setup > Measurements > Density > Density Damping
Overview
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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value.
Procedure
Offline Maintain > Configuration > Damping > Density Damping
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table:
Core processor type Update Rate setting Density Damping range
Standard Normal 0 to 51.2 seconds
Special 0 to 10.24 seconds
Enhanced Not applicable 0 to 40.96 seconds
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
The value you enter is automaticaly rounded down to the nearest valid value. The valid
values for Density Damping depend on the setting of Update Rate.

Enhanced Not applicable 0, 0.04, 0.08, 0.16, ... 40.96
Effect of Density Damping on volume measurement
Density Damping affects liquid volume measurement. Liquid volume values are calculated
from the damped density value rather than the measured density value. Density Damping
does not affect gas standard volume measurement.
Interaction between Density Damping and Added Damping
In some circumstances, both Density Damping and Added Damping are applied to the reported
density value.
Density Damping controls the rate of change in the density process variable. Added Damping
controls the rate of change reported via the mA output. If mA Output Process Variable is set to
Density, and both Density Damping and Added Damping are set to non-zero values, density
damping is applied first, and the added damping calculation is applied to the result of the
first calculation.

Density Cutoff specifies the lowest density value that will be reported as measured. All
density values below this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
The default value for Density Cutoff is 0.2 g/cm3. The range is 0.0 g/cm3 to 0.5 g/cm3.

Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density
Cutoff, the volume flow rate is reported as 0. Density Cutoff does not affect gas standard
volume measurement. Gas standard volume values are always calculated from the value
configured for Standard Gas Density.
4.6 Configure temperature measurement
The temperature measurement parameters control how temperature data from the
sensor is reported. Temperature data is used to compensate for the effect of temperature
on the sensor tubes during flow measurement .

changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual

for Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 76.8.
Effect of Temperature Damping on process measurement
Temperature Damping affects the response speed for temperature compensation with
fluctuating temperatures. Temperature compensation adjusts the process measurement
to compensate for the effect of temperature on the sensor tube.
Temperature Damping affects petroleum measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for petroleum measurement, Temperature Damping does not
affect petroleum measurement process variables.
Temperature Damping affects concentration measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for concentration measurement, Temperature Damping does not
affect concentration measurement process variables.
4.7 Configure the petroleum measurement application

4.8 Configure the concentration measurement application
The concentration measurement application calculates concentration data from process
temperature and density. Micro Motion provides a set of concentration matrices that
provide the reference data for several standard industry applications and process fluids. If
desired, you can build a custom matrix for your process fluid, or purchase a custom matrix
from Micro Motion.
More information about the concentration measurement application is available in the
following manual: Micro Motion Enhanced Density Application: Theory, Configuration, and
Use.
Configuration and Use Manual 61
Page 70
Configure process measurement
Note
The concentration measurement application is also known as the enhanced density application.
4.8.1 Configure concentration measurement using ProLink II
This task guides you through loading and setting up a concentration matrix to use for
measurement. It does not cover building a concentration matrix.
Note
Concentration matrices can be made available on your transmitter either by loading an existing
matrix from a file or by building a new matrix. Up to six matrices can be available on your transmitter,
but only one can be used for measurement at any given time. See Micro Motion Enhanced Density
Application: Theory, Configuration, and Use for detailed information on building a matrix.
Prerequisites
Before you can configure concentration measurement:
• The concentration measurement application must be enabled on your transmitter.
• The concentration matrix you want to use must be available on your transmitter, or
it must be available as a file on your computer.
• You must know the derived variable that your matrix is designed for.
• You must know the density unit used by your matrix.
• You must know the temperature unit used by your matrix.
• The concentration measurement application must be unlocked.
Procedure
1.
Choose ProLink > Configuration > Density and set Density Units to the density unit used by
your matrix.
2. Choose ProLink > Configuration > Temperature and set Temp Units to the temperature unit
used by your matrix.
3. Choose ProLink > Configuration > CM Setup.
4. In Global Config, set Derived Variable to the derived variable that your matrix is
designed for.
Important
• All concentration matrices on your transmitter must use the same derived variable. If you
are using one of the standard matrices from Micro Motion, set Derived Variable to Mass Conc
(Density). If you are using a custom matrix, see the reference information for your matrix.
• If you change the setting of Derived Variable, all existing concentration matrices will be
deleted from transmitter memory. Set Derived Variable before loading concentration
matrices.
5. Load one or more matrices.

a. In Curve Specific Config, set Curve Configured to the location to which the matrix
will be loaded.
b.
Click Load this curve from a file, navigate to the matrix file on your PC, and load it.
c. Repeat until all required matrices are loaded.
6. Set up extrapolation alarms.
Each concentration matrix is built for a specific density range and a specific
temperature range. If process density or process temperature goes outside the
range, the transmitter will extrapolate concentration values. However, extrapolation
may affect accuracy. Extrapolation alarms are used to notify the operator that
extrapolation is occurring.
a. In Curve Specific Config, set Curve Configured to the matrix that you want to
configure.
b. Set Alarm Limit to the point, in percent, at which an extrapolation alarm will be
posted.
c. Enable or disable the high and low limit alarms for temperature and density, as
desired.
Restriction
The high and low limit alarms require the enhanced core processor.
Example: If Alarm Limit is set to 5%, Enable Temp High is checked, and the matrix is built
for a temperature range of 40 °F to 80 °F, an extrapolation alarm will be posted if
process temperature goes above 82 °F

Pressure compensation adjusts process measurement to compensate for the pressure
effect on the sensor. The pressure effect is the change in the sensor’s sensitivity to flow
and density caused by the difference between the calibration pressure and the process
pressure.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific
sensor model can be found in the product data sheet located at www.micromotion.com. If you are
uncertain about implementing pressure compensation, contact Micro Motion customer service.

display. You can set Display Precision independently for each variable.
Setting Display Precision does not affect the actual value of the process variable.
Offline Maintain > Configuration > Display > Num of Decimals
Procedure
1.
Select a process variable.
2. Set Display Precision to the number of decimal places you want shown when the
process variable appears on the display.
For temperature and density process variables, the default value is 2 decimal places.
For all other process variables, the default value is 4 decimal places. The range is
0 to 5.
Tip
The lower the selected precision, the greater the process change must be for it to be reflected
on the display. Do not set Display Precision value too low or too high to be useful.

ProLink III Device Tools > Configuration > Process Measurement > Response > Update Rate
Field Communicator Configure > Manual Setup > Measurements > Update Rate
Overview
Update Rate controls the rate at which process data is polled and process variables are
calculated. Update Rate = Special produces faster and “noisier” response to changes in the
process. Do not use Special mode unless required by your application.
Tip
For systems with a standard core processor, Special mode can improve performance for applications
with entrained air or Empty-Full-Empty conditions. This does not apply to systems with an enhanced
core processor.
