Setting Units Units for both the Sensor Transducer Block and the AI Block are set in the AI

Block. To change units:

• Set the AI Block to OOS mode

• Select XD_Scale.units_index

• Select only one of the engineering units listed on page 3-10

• Return AI Block to Auto mode

ZEROING TRANSMITTER Before operating the transmitter, perform a Zero Trim and set the Damping.

Refer to page 4-4 for zeroing procedures.

Damping The damping parameter in the Transducer Block may be used to filter

measurement noise. By increasing the damping time, the transmitter will have

a slower response time, but will decrease the amount of process noise that is

translated to the Transducer Block Primary Value. Because both the LCD and

AI Block get input from the Transducer Block, adjusting the damping

parameter will effect both blocks.

NOTE

The AI Block has it's own filtering parameter called PV_FTIME. For simplicity,

it is better to do filtering in the Transducer Block as damping will be applied to

primary value on every sensor update. If filtering is done in AI block, damping

will be applied to output every macrocycle.

ROSEMOUNT 305, 306

AND 304 MANIFOLDS

The Rosemount 305 is available in two designs: Traditional and Coplanar.

The traditional 305 Integral Manifold can be mounted to most primary

elements with mounting adapters in the market today. The Rosemount 306

In-Line Manifold is used with In-line transmitters to provide block-and-bleed

valve capabilities of up to 10000 psi (690 bar). The Rosemount 304 comes in

two basic styles: traditional (flange x flange and flange x pipe) and wafer. The

304 traditional manifold comes in 2, 3, and 5-valve configurations. The 304

wafer manifold comes in 3 and 5 valve configurations.
