•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
2.1Power 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.
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.
2.2Check flowmeter status
Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.
Configuration and Use Manual 5
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.
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.

2.4.2Flow 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
10 Micro Motion® Model 1700 Transmitters with Analog Outputs
Quick start
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
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.
2.5Verify 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 11
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 10.3.
2.6Verify 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.
2.6.1Verify 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.
12 Micro Motion® Model 1700 Transmitters with Analog Outputs
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.
2.6.2Verify 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.

2.6.3Terminology used with zero verification and zero
calibration
Terminology used with zero verification and zero calibrationTable 2-2:
TermDefinition
ZeroIn general, the offset required to synchronize the left pickoff and the right pickoff under
conditions of zero flow. Unit = microseconds.
Factory ZeroThe zero value obtained at the factory, under laboratory conditions.
Field ZeroThe zero value obtained by performing a zero calibration outside the factory.
Prior ZeroThe 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 ZeroThe 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 ZeroThe 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 StabilityA 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 CalibrationThe 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.
Offline Maintain > Configuration > Units > Special Mass Flow
Procedure
1.Specify Base Mass Unit.
Base Mass Unit is the existing mass unit that the special unit will be based on.
2.Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3.Calculate Mass Flow Conversion Factor as follows:
a. x base units = y special units
b. Mass Flow Conversion Factor = x/y
4.Enter Mass Flow Conversion Factor.
5.Set Mass Flow Label to the name you want to use for the mass flow unit.
6.Set Mass Total Label to the name you want to use for the mass total and mass
inventory unit.
The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).
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 typeUpdate Rate settingFlow Damping range
StandardNormal0 to 51.2 seconds
Special0 to 10.24 seconds
EnhancedNot applicable0 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.
