Prerequisites
Verify the zero and prepare the meter using the procedures in
.
Procedure

If necessary, modify Zero Time. 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.
Postrequisites
Restore normal flow through the sensor by opening the valves. Verify that the sensor tubes
are full.
Need help?
If the zero fails:
•
Verify 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 customer service.

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. The flowmeter’s actual
measurement is multiplied by the meter factor, and the resulting value is reported and
used in further processing.
