Following installation, perform zero calibration prior
to commissioning the device. Finalise the installation
before performing zero calibration. Changes (pipe
system or calibration factor) made after the zero
calibration may affect the accuracy, making it
necessary to perform zero calibration again.
•
The measuring sensor should be completely filled
with the product at the expected process pressure
and temperature.
•
The product may contain no air or gas, especially
when it comes to horizontal installations. Prior to zero
calibration, it is recommended that the product be
flushed at a high flow rate (>50%), for 2 minutes.
•
After flushing, re-establish zero flow by closing off the
corresponding valves.
Set zero calibration automatically or manually using
the operating controls. The converter cover must be
installed on the display for automatic calibration.
