Transducer block
The transducer block contains the parameters required to calibrate the device. These
parameters can also be addressed by using the VU 331 display module. The calibration
of the device is described in Chapter 5.5.5 to Chapter 5.5.7
Operation
The transducer block is opened by clicking on the transducer line.
Parameter changes from the tool are made off-line while the device is operating. The
changes are downloaded by first setting MODE_BLK = OOS then pressing the WRITE
CHANGES button. Press the READ ALL button to check the values stored in the device.
Normally operation is resumed as soon as MODE-BLK is set to AUTO.

Configuration parameters
The transducer block also contains the configuration parameters, which are used to
commission and calibrate the instrument. They are identical to the functions of the
operating menu (see page 94), except for the service parameters which are not
accessible on the bus. Thus, the calibration procedure via the display module (Chapter
6.4) is equally valid for a calibration via a network configuration tool.
A complete list of the configuration parameters can be found in the "Description of
Instrument Functions", BA 245F/00/en.
