Sensor High trim by PC

Sensor High trim by P C is available us ing dedicated Software. ABB can provide the references and t he
Software.

Sensor Static trim

The purpose of this procedure is to o ptimize transmitter performance by reducing the effect of static line
pressure in these appli cations. 2600T Pressure transmitter Series does not normally require this procedure
because optimization based on facto ry characterization occurs in the sen sor. In any case this trim ca n be
performed if required.

Static trim by HHT

Sensor Static trim by Ha nd Held T erminal is avai lable. Please refer to the device man ual for the ri ght
operations.

Static trim by PC

Sensor Static trim by PC i s available using dedicated Software. ABB can prov ide the references and the

Calibration

Calibration is an operatio n by which t he LRV and URV are adjusted. It sets the 4 and 20 mA points at
required pressures.
See Basic Configuration Function, Set the LRV and Set the URV for the procedures.

Output trimming (Digital to Analog trim)

The Analog Output Trim allows the adjustment of the transmitter's current output at the 4 and 20 mA points
to match the plant standards. This command adjusts the digital to analog signal conversion.
