If the zero procedure failed, a
Calibration Failed
message is displayed.
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 customer service.

Term
Definition
Zero
In general, the offset required to synchronize the left pickoff and the right pickoff under
conditions of zero flow. Unit = microseconds.
Factory Zero
The zero value obtained at the factory, under laboratory conditions.
Field Zero
The zero value obtained by performing a zero calibration outside the factory.
Prior Zero
The zero value stored in the transmitter at the time a field zero calibration is begun. May
be the factory zero or a previous field zero.
