Operation
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.
Output trimming by Digital LCD Integral Display
To set the 4 mA output current
Connect the pressure transmitter as defined in the Trimming and Calibration Set Up. Using a precison
milliamperometer read the current output. Navigate the Digital LCD Integral Display menu, select
Calibrate
>
Output Trim
>
Set 4 mA
and the value will be available. To modify select
Edit
then scroll the desired value
with the up and down keys and confirm with
Next.
Repeat the operation for the seven digits to have the
same reading of the milliamperometer and confirm with
OK.
Note: the Maximum and Minimum values are indicated on the Display as reference.

Digital LCD Integral Display Keys sequence to set the 4 mA output current: 6 – 2 – 1 – Edit
To set the 20 mA output current
Connect the pressure transmitter as defined in the Trimming and Calibration Set Up. Using a precison
milliamperometer read the current at the output. Navigate the Digital LCD Integral Display menu, select
Calibrate
>
Output Trim
>
Set 20 mA
and the value will be available. To modify select
Edit
then scroll the
desired value with the up and down keys and confirm with
Next.
Repeat the operation for the seven digits to
have the same reading of the milliamperometer and confirm with
OK.
Note: the Maximum and Minimum values are indicated on the Display as reference.

Digital LCD Integral Display Keys sequence to set the 20 mA output current: 6 – 2 – 2 – Edit
Output trimming by CoMeter
Output trimming by CoMeter is available with the 695 Field Indicator. Please refer to the device manual for
the appropriate operations.
