2 Quick start
Topics covered in this chapter:
• Power up the transmitter
• Check meter status
• Make a startup connection to the transmitter
• Zero the meter
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.
Quick start
WARNING!
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,
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.
Configuration and Use Manual 7
Quick start
2. Check the status LED on the transmitter.
Transmitter status reported by status LEDTable 2-1:
LED state Description Recommendation
Green No alerts are active. Continue with configuration or process meas-
urement.
Yellow One or more low-severity alerts are active. A low-severity alert condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or process measurement. If you choose, you can identify and resolve the alert condition.
Flashing yellow Calibration in progress, or Known Density Veri-
fication in progress.

calibration process or change as a result of the
calibration process. The alert will clear when
the calibration is complete. Check the calibration results before continuing.
urement accuracy and output behavior. Resolve the alert condition before continuing.
• View and acknowledge status alerts (Section 8.3)
• Status alerts, causes, and recommendations (Section 10.6)
2.3 Make a startup connection to the transmitter
For all configuration tools except the display, you must have an active connection to the
transmitter to configure the transmitter.
Identify the connection type to use, and follow the instructions for that connection type in
the appropriate appendix. Use the default communications parameters shown in the
appendix.
Communications tool Connection type to use Instructions
ProLink III Modbus/RS-485
HART/Bell 202
Field Communicator HART/Bell 202 Appendix D
Postrequisites
(Optional) Change the communications parameters to site-specific values.
Appendix C
• To change the communications parameters using ProLink III, choose Device Tools >
Configuration > Communications.
8 Micro Motion® Compact Density Meters (CDM)
• To change the communications parameters using the Field Communicator, choose
Configure > Manual Setup > HART > Communications.
Important
If you are changing communications parameters for the connection type that you are using, you will
lose the connection when you write the parameters to the transmitter. Reconnect using the new
parameters.
2.4 Zero the meter
Zeroing the meter establishes a baseline for the velocity indicator by analyzing the sensor's
output when there is no flow through the sensor tubes.
Note
Do not zero the meter if a high-severity alert is active. Correct the problem, then zero the meter. You
may zero the meter if a low-severity alert is active.
In most cases, the default value (0) is adequate for flow indication. Do not zero the meter unless the
velocity switch is being triggered incorrectly and you need to apply an offset to the velocity
measurement.
Quick start
• Zero the meter using the display (Section 2.4.1)
• Zero the meter using ProLink III (Section 2.4.2)
• Zero the meter using the Field Communicator (Section 2.4.3)
2.4.1 Zero the meter using the display
Restriction
You cannot change the Zero Time setting from the display. The current setting of Zero Time will be
applied to the zero procedure. The default value is 20 seconds. If you need to change Zero Time, you
must make a connection to the transmitter from a communications tool such as ProLink III.
Procedure
1. Prepare the meter:
a. Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
b. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
c. Verify that the process fluid is not flashing or condensing, and that it does not
contain particles that can settle out.
d. Remove or reduce sources of electromechanical noise if appropriate.
2. Start the zero process.
a. Navigate to the Zero menu: OFFLINE MAINT > OFFLINE CALIB > VEL ZERO.
Configuration and Use Manual 9
Quick start
b. Scroll to CAL VEL/ZERO and activate Select, then select CAL/YES?.
The status LED changes to flashing yellow while the zero is in progress.
3. Read the zero result on the display.
The display reports CAL PASS if the zero was successful, or CAL FAIL if it was not.
Postrequisites
Restore normal flow through the sensor by opening the valves.
Need help? If the zero fails:
• Ensure that there is no flow through the sensor, then retry.
• Remove or reduce sources of electromechanical noise, then retry.
• Set Zero Time to a lower value, then retry.
• If the zero continues to fail, contact Micro Motion.
• If you want to return the meter to operation using a previous zero value, choose OFFLINE
MAINT > CAL > RESTORE VEL/ZERO.
2.4.2 Zero the meter using ProLink III
1. Prepare the meter:
a. Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
b. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
c. Verify that the process fluid is not flashing or condensing, and that it does not
contain particles that can settle out.
d. Remove or reduce sources of electromechanical noise if appropriate.
2. Choose Device Tools > Calibration > Zero Velocity.
3. Modify Zero Time, if desired.
Zero Time controls the amount of time the transmitter takes to determine its zeroflow reference point. The default Zero Time is 20 seconds. For most applications, the
default Zero Time is appropriate.
4. Click Calibrate Zero.
The Calibration in Progress message is displayed. When the calibration is
complete:
• If the zero procedure was successful, a Calibration Success message and a
new zero value are displayed.
• If the zero procedure failed, a Calibration Failed message is displayed.
Postrequisites
Restore normal flow through the sensor by opening the valves.
10 Micro Motion® Compact Density Meters (CDM)
Need help? If the zero fails:
• Remove or reduce sources of electromechanical noise, then retry.
• If the zero continues to fail, contact Micro Motion.
• If you want to return the meter to operation using a previous zero value, choose Device Tools >
Calibration > Zero Velocity > Restore Prior Zero. Restore Prior Zero is available only while the Zero
Velocity window is open. If you close the Zero Velocity window, you will no longer be able to
restore the prior zero.
2.4.3 Zero the meter using the Field Communicator
1. Prepare the meter:
a. Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
b. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is

3.4 Set the HART lock
If you plan to use a HART connection to configure the device, you can lock out all other
HART masters. If you do this, other HART masters will be able to read data from the device
but will not be able to write data to the device.
Restrictions
• This feature is available only when you are using the Field Communicator or AMS.
• This feature is available only with a HART 7 host.
Procedure
1. Choose Configure > Manual Setup > Security > Lock/Unlock Device.
2. If you are locking the meter, set Lock Option as desired.
Introduction to configuration and commissioning
Option Description
Permanent Only the current HART master can make changes to the device. The device will
remain locked until manually unlocked by a HART master. The HART master can
also change Lock Option to Temporary.
Temporary Only the current HART master can make changes to the device. The device will
remain locked until manually unlocked by a HART master, or a power-cycle or
device reset is performed. The HART master can also change Lock Option to Perma-
nent.
Lock All No HART masters are allowed to make changes to the configuration. Before
changing Lock Option to Permanent or Temporary, the device must be unlocked. Any
HART master can be used to unlock the device.
Postrequisites
To avoid future confusion or difficulties, ensure that the device is unlocked after you have
completed your tasks.

Introduction to configuration and commissioning
Overview
Restoring the factory configuration returns the transmitter to a known operational
configuration. This may be useful if you experience problems during configuration.
Tip
Restoring the factory configuration is not a common action. You may want to contact Micro Motion
to see if there is a preferred method to resolve any issues.

4.1 Verify the calibration factors
Display Not available
ProLink III Device Tools > Calibration Data
Field Communicator Configure > Manual Setup > Calibration Factors
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
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.
Configuration and Use Manual 21

4.1.1 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.
Contents of the calibration certificate
The calibration certificate contains several sets of factors:
Density calibration
coefficients
Temperature
compensation coefficients
Pressure compensation
coefficients
Flow compensation
coefficient
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.
CDM format and legacy format (A factors and K factors)
The calibration factors are provided on three calibration certificates:
• The first certificate provides the calibration factors in the CDM format, An, in SI units.
These are obtained from factory calibration of your device.
• The second certificate provides the calibration factors in the legacy format, Kn, in SI
units. These factors represent the current calibration factors converted to the
format used by the 7835 and 7845 meters.
• The third certificate provides the calibration factors in the legacy format, Kn, in
imperial units. These factors represent the current calibration factors converted to
the format used by the 7835 and 7845 meters, and then converted to imperial units.
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 pressure on
sensor response
Adjusts density measurement for the effect of flow on
sensor response
If you have existing programs that use the K factors, update your programs with the new K
values in the appropriate units. In all other situations, use the A-format calibration factors.
