9 Measurement support Topics covered in this chapter: • Options for measurement support • Zero the flowmeter • Validate the meter • Perform a (standard) D1 and D2 density calibration • Perform a D3 and D4 density calibration (T-Series sensors only) • Perform temperature calibration 9.
Prerequisites Before performing a field zero, execute the Zero Verification procedure to see whether or not a field zero can improve measurement accuracy. See Section 2.6 . Important Do not verify the zero or zero the flowmeter if a high-severity alarm is active.
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.
Zero Time controls the amount of time the transmitter takes to determine its zero- flow reference point. The default Zero Time is 20 seconds. For most applications, the default Zero Time is appropriate. 5. Click Perform Auto Zero . The Calibration in Progress light will turn red during the zero procedure.
e. Observe the drive gain, temperature, and density readings. If they are stable, check the Live Zero or Field Verification Zero value. If the average value is close to 0, you should not need to zero the flowmeter. 2. Press Service Tools > Maintenance > Zero Calibration > Perform Auto Zero .
Overview Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. If the transmitter value for mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor.
3. Configure the meter factor in the transmitter. Example: Calculating the meter factor for mass flow The flowmeter is installed and validated for the first time. The mass flow measurement from the transmitter is 250.27 lb. The mass flow measurement from the reference device is 250 lb.
3. Ensure that the calculated meter factor is between 0.8 and 1.2, inclusive. If the meter factor is outside these limits, contact Micro Motion customer service.

For more information on using sensor simulation, see #unique_253 . 10.9 Check power supply wiring If the power supply wiring is damaged or improperly connected, the transmitter may not receive enough power to operate properly. Prerequisites You will need the installation manual for your transmitter.
10.10 Check sensor-to-transmitter wiring A number of power-supply and output problems may occur if the wiring between the sensor and the transmitter is improperly connected, or if the wiring becomes damaged. Prerequisites You will need the installation manual for your transmitter.
10.12.1 Perform loop tests using the display A loop test is a way to verify that the transmitter and the remote device are communicating properly. A loop test also helps you know whether you need to trim mA outputs.
a. Choose OFFLINE MAINT > SIM > DO SIM , and select SET ON . Dots traverse the display while the output is fixed. b. Verify the signal at the receiving device. c. At the transmitter, activate Select . d. Scroll to and select SET OFF . e. Verify the signal at the receiving device.
Procedure 1. Test the mA output(s). a. Choose ProLink > Test > Fix Milliamp . b. Enter 0 mA or 4 mA in Set Output To . c. Click Fix mA . d. Read the mA current at the receiving device and compare it to the transmitter output. The readings do not need to match exactly.
d. Set the remote input device to OFF. e. Choose ProLink > Test > Read Discrete Input . f. Verify the signal at the transmitter. 5. Test the mA input. a. Set the remote input device to generate a known fixed current. b. Choose ProLink > Test > Read MA Input .
f. Read the mA current at the receiving device and compare it to the transmitter output. The readings do not need to match exactly. If the values are slightly different, you can correct the discrepancy by trimming the output. g. Press OK . h. Choose End .
10.13.1 Trim mA outputs using ProLink II Trimming the mA output establishes a common measurement range between the transmitter and the device that receives the mA output. Important You must trim the output at both ends (0 mA or 4 mA, and 20 mA) to ensure that it is compensated accurately across the entire output range.
Important The HART signal over the primary mA output affects the mA reading. Disconnect the wiring between the Field Communicator and the transmitter terminals when reading the primary mA output at the receiving device. Reconnect to continue the trim.
10.15 Check HART Address and Loop Current Mode If the transmitter is producing a fixed current from the mA output, the Loop Current Mode parameter may be disabled. When Loop Current Mode is disabled, the mA output produces a fixed value, and does not report process data or implement its fault action.
1. Check the status alarms for active fault conditons. 2. If there are active fault conditions, the transmitter is performing correctly. If you want to change its behavior, consider the following options: • Change the setting of mA Output Fault Action .
2. If you changed the setting of Frequency Output Scaling Method , check the settings of all other frequency output parameters. 10.22 Check Frequency Output Fault Action The Frequency Output Fault Action controls the behavior of the frequency output if the transmitter encounters an internal fault condition.
Tip For typical applications, Micro Motion recommends setting Mass Flow Cutoff to the zero stability value for your sensor, multiplied by 10. Zero stabiliy values can be found in the Product Data Sheet for your sensor. 10.25 Check for slug flow (two-phase flow) Slug flow (two-phase flow, entrained gas) can cause spikes in the drive gain.
Possible causes and recommended actions for excessive (saturated) drive gain (continued) Table 10-8: Possible cause Recommended actions Cavitation, flashing, or air en- trainment; settling of two- or three-phase fluids • Increase the inlet or back pressure at the sensor.
Overview Drive gain data can be used to diagnose a variety of process and equipment conditions. Collect drive gain data from a period of normal operation, and use this data as a baseline for troubleshooting. Procedure 1. Navigate to the drive gain data.
10.27.1 Collect pickoff voltage data ProLink II ProLink > Diagnostic Information Field Communicator Service Tools > Maintenance > Diagnostic Variables Overview Pickoff voltage data can be used to diagnose a variety of process and equipment conditions.
Procedure 1. Disconnect power to the transmitter. CAUTION! If the transmitter is in a hazardous area, wait 5 minutes before continuing. 2. Remove the transmitter housing cover. 3. Unplug the terminal blocks from the terminal board on the core processor.
6. Test the resistance of junction box terminal pairs. a. Test the brown terminal against all other terminals except the red one. b. Test the red terminal against all other terminals except the brown one. c. Test the green terminal against all other terminals except the white one.
