7.0 Zero trim the transmitter

Transmitters are shipped fully calibrated per request or by the factory default of
full scale.
A zero trim is a single-point adjustment used for compensating mounting
position and line pressure effects. Use the steps below if zero offset is less than 5%
of URL.
1. When performing a zero trim, ensure the equalizing valve is open and all wet
legs are filled to the correct level. Make sure the transmitter is connected to
the host system.
2. Zero the differential pressure sensor by using the "Zero Differential Pressure"
method in the host system.
3. Follow the zero DP trim procedure.
4. Zero the static pressure sensor by using the "Zero Static Pressure" or the
"Lower Static Pressure Trim" method in the host system.
a. Use the "Zero Static Pressure" for a transmitter equipped with a gage static
pressure sensor and the "Lower Static Pressure Trim" for a transmitter
equipped with an absolute static pressure sensor.
Note
When performing a lower sensor trim on a pressure sensor, it is possible to degrade the
performance of the sensor if inaccurate calibration equipment is used. Use calibration
equipment that is at least three times as accurate as the pressure sensor of the Rosemount
3051SMV F
