Sensor High trim by PC

Sensor High trim by PC is available using dedicated Software. ABB can provide the references and the
Software.

Sensor Static trim

The purpose of this procedure is to optimize transmitter performance by reducing the effect of static line
pressure in these applications. 2600T Pressure transmitter Series does not normally require this procedure
because optimization based on factory characterization occurs in the sensor. In any case this trim can be
performed if required.

Static trim by HHT

Sensor Static trim by Hand Held Terminal is available. Please refer to the device manual for the right
operations.

Static trim by PC

Sensor Static trim by PC is available using dedicated Software. ABB can provide the references and the
Software.

Calibration

The Calibration is an operation by which the 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.
