1.3 Communications tools and protocols You can use several different communications tools and protocols to interface with the device. You may use different tools in different locations or for different tasks.
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.
Transmitter status reported by status LED Table 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.
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.

5. Replace the safety spacer and end-cap. 6. Power up the meter. 3.4 Set the HART lock If you plan to use a HART connection to configure the meter, you can lock out all other HART masters. If you do this, other HART masters will be able to read data from the meter but will not be able to write data to the meter.
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.

• If the values do not match, contact Micro Motion customer service. Related information Sample calibration certificate 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.

b. Kinematic Viscosity Special Unit Conversion Factor = x ÷ y 2. Enter Kinematic Viscosity Special Unit Conversion Factor . 3. Set User-Defined Label to the name you want to use for the kinematic viscosity unit. The special measurement unit is stored in the transmitter.
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.
Options for Density Measurement Unit The transmitter provides a standard set of measurement units for Density Measurement Unit . Different communications tools may use different labels.
a. x base units = y special units b. Density Special Unit Conversion Factor = x/y 3. Enter Density Special Unit Conversion Factor . 4. Set User-Defined Label to the name you want to use for the density unit. The special measurement unit is stored in the transmitter.
Density 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.
Procedure 1. Set Two-Phase Flow Low Limit to the lowest density value that is considered normal in your process. Values below this will cause the transmitter to post Alert A105 (). Tip Gas entrainment can cause your process density to drop temporarily.
• Line density reverts to actual process density. • The two-phase flow alert is deactivated, but remains in the active alert log until it is acknowledged. If the two-phase flow condition does not clear before Two-Phase Flow Timeout expires, line density reverts to actual process density, but the two-phase flow alert remains active.
Options for Temperature Measurement Unit The transmitter provides a standard set of units for Temperature Measurement Unit . Different communications tools may use different labels for the units.
• 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.

2. Set Altitude to the value that is closest to the altitude of your meter, measured from sea level. Valid values are 0000 to 6000 feet, and 0000 to 2000 meters. 3. Click Next to start the procedure. 4. Wait while the meter collects and analyzes process data.
The default value is 0. The range is unlimited. 9.3 Adjust viscosity measurement with Viscosity Meter Factor You can adjust viscosity measurement by applying a viscosity meter factor. The measured dynamic viscosity is always multiplied by the viscosity meter factor.
Procedure 1. Activate SCROLL . 2. Check the current viscosity range. The meter factor will be calculated for this range, and applied only to viscosity measurements in this range. If you want to calculate a meter factor for a different range, you must change the viscosity of your process fluid.
Prerequisites Referred viscosity measurement must be configured before you can use the meter to calculate the viscosity meter factor. If you are not using referred viscosity, you must enter the viscosity meter factor manually. You must be able to obtain a laboratory value for the dynamic viscosity of your process fluid at Reference Temperature 1.
Your meter is calibrated for one to four viscosity ranges. There is a separate meter factor for each range. You can calculate or enter a meter factor for any or all of the viscosity ranges. Tip You can adjust line viscosity measurement with Viscosity Meter Factor , Viscosity Offset , or both.
9.3.4 Calculate and enter Viscosity Meter Factor manually You can adjust viscosity measurement by applying a viscosity meter factor. The measured dynamic viscosity is always multiplied by the viscosity meter factor. The result is used in further calculations.
9.4 Adjust density measurement with Density Offset or Density Meter Factor You can adjust the reported density measurement by modifying the value for Density Offset or Density Meter Factor . The measured density value is always multiplied by the density meter factor.
Tip In most cases, you will calculate and set only one parameter. Follow the guidelines established for your site. 5. If you are using the offset to adjust density measurement, set Density Offset to the calculated value.
Restriction Density offset calibration is available only when API referral or concentration measurement is enabled on your meter. If neither of these is enabled, Density Offset must be entered manually.
9.5.2 Perform density offset calibration using ProLink III Density offset calibration is used to verify or adjust the value of Density Offset . Density Offset is always added to the measured density value after the density meter factor is applied, and before other processing is performed.
5. For concentration measurement: Check the values displayed in the Density Offset and Referred Density (Concentration) fields. If the calibration succeeded: • Density Offset displays the updated value for this parameter. • Referred Density (Concentration) shows this process variable with the new density offset applied.
2. Enter the laboratory reference value. 3. Press OK and wait for a few seconds while the calibration process is performed. 9.6 Adjust temperature measurement with Temperature Offset or Temperature Slope You can adjust the line temperature measurement by modifying the value for Temperature Offset or Temperature Slope .

Procedure 1. Take a concentration reading from the meter, and record line density and line temperature. 2. Take a sample of the process fluid and obtain a laboratory value for concentration at line density and line temperature, in the units used by the meter.
Prerequisites You must be able to take measurements of your process fluid at two different concentrations. You must be able to take a sample of your process fluid at each of these concentrations. For each sample, you must be able to obtain a laboratory concentration value at line density and line temperature.

10 Troubleshooting Topics covered in this chapter: • Quick guide to troubleshooting • Check power supply wiring • Check grounding • Perform loop tests • Status LED states • Status alerts, .
• If this is a first installation: - Verify the power wiring and power supply. - Verify the output wiring. The outputs must be powered externally. - Verify the grounding. - Verify cable shielding. - Perform loop tests for each output. - Check the sensor installation and orientation.
2. Before inspecting the power supply wiring, disconnect the power source. CAUTION! If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. 3. Ensure that the terminals, wires, and wiring compartment are clean and dry.
