Restore the factory zero only if your meter was purchased as a unit, it was zeroed at the factory, and
you are using the original components.

Start the zero procedure and wait until it completes.
When the calibration is complete:
• If the zero procedure was successful, a Calibration Success message and a
new zero value are displayed.
• If the zero procedure failed, a Calibration Failed message is displayed.
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.
If you want to restore the most recent valid value from transmitter memory:
- Using the display: Menu > Service Tools > Verification and Calibration > Meter Zero >
Restore Zero > Restore Previous Zero
- Using ProLink III: Device Tools > Calibration > Smart Zero Verification and Calibration >
Calibrate Zero > Restore Prior Zero
If you want to restore the factory zero:
- Using the display: Menu > Service Tools > Verification and Calibration > Meter Zero >
Restore Zero > Restore Factory Zero
- Using ProLink III: Device Tools > Calibration > Smart Zero Verification and Calibration >
Calibrate Zero > Restore Factory Zero
Verify the zero
Definition
In general, the offset required to synchronize the left pickoff and the right
pickoff under conditions of zero flow. Unit = microseconds.
The zero value obtained at the factory, under laboratory conditions.
The zero value obtained by performing a zero calibration outside the fac-
tory.
