Flowmeter Startup continued
3. Fill the flowmeter completely with the process fluid under normal process conditions of
temperature, density, pressure, etc., and ensure zero flow through the flowmeter.
4. Make sure flow through the meter is completely stopped, then press and hold the zero button
until the LED remains on continuously. See Figure 5-1.
To end the zero operation before its completion, cycle power to the flowmeter.
The LED remains on continuously and the optional display reads “ZERO0” for up to one minute
during zeroing. After the zeroing procedure has been completed, the LED again blinks ON once per
second to indicate normal operation, and the optional display again indicates the flow rate.
5.5.2 Diagnosing zero failure
If zeroing fails:
The LED blinks ON four times per second.
The flowmeter produces fault outputs.
The blinking message “ELEC0” appears in the optional display.
An error condition could be caused by any of the following:
Flow of fluid during flowmeter zeroing
Partially empty flow tubes
An improperly mounted flowmeter
To clear a zeroing error, cycle power, then re-zero the flowmeter after correcting the problem, or abort
the procedure by cycling power to the flowmeter.
5.6 Configuration, calibration, and characterization
The following information explains the difference between configuration, calibration, and
characterization. Certain parameters might require configuration even when calibration is not
necessary.
Configuration parameters include such items as flow cutoff and damping values, flow direction, and
milliamp output scaling. If requested at time of order, the meter is configured at the factory according
to customer specifications.
Calibration parameters include the calibration factors for flow, density, and temperature. Field
calibration is optional.
Characterization is the process of using a communication device to enter calibration factors for flow,
density, and temperature directly into flowmeter memory, instead of performing field calibration
procedures. Calibration factors can be found on the flowmeter serial number tag and on the certificate
that is shipped with the meter.
To configure, calibrate, or characterize the flowmeter:
Using a HART Communicator, see Chapter 6
Using ProLink II software, see Chapter 7
You can also use AMS software to configure and characterize Micro Motion flowmeters. For
instructions on using AMS software, refer to the AMS on-line help.
