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.

3.
Modify
Zero Time
, if desired.
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.
4.
Press
Perform Auto Zero
to start the zero, and wait while the zero calibration is
performed.
5.
When the zero is complete, data from the zero calibration is displayed.
•
Press
OK
to accept the data and store the values.
•
Press
ABORT
to discard the data and return to the previous zero values.
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.
