10.2. Configuration and Calibration
10.2.1. The transmitter has features which enable metrological and identification parameters to be set and
altered. The configurable metrological parameters affecting the transmitter’s output current include the
following:
a) unit in which the measured pressure is expressed on the display
b) upper end-point of the set range
c) lower end-point of the set range
d) time constant
e) type of characteristic curve: linear or radical
Parameters of an informational nature which cannot be altered include the following:
f) upper limit of the basic range
g) lower limit of the basic range
h) minimum range
10.2.2. Other identification parameters, not affecting the output signal, include: device address, device type
code, factory identification code, factory device code, number of preambles (3÷20), UCS, TSD, program
version, electronics version, flags, serial number, label tag, description tag, date tag, message, record number,
sensing module number.
The process of setting the parameters listed in 10.2.1 and 10.2.2 is called “Configuration”.
10.2.3. It is possible to carry out a “pressure zeroing” procedure, for example to compensate for
measurement deviation caused by a change in position during the transmitter installation.
The transmitter may also be calibrated, by taking readings with the input pressure controlled using a standard
device. This process and zero-point adjustment are called “Calibration”.
10.2.4. Configuration and Calibration of the transmitter are carried out using an Aplisens KAP communicator,
certain Hart communicators or a PC with Hart/RS232 converter and Aplisens “Raport” software.
Together with the “RAPORT” configuration software there is a „INTERVAL LINEARIZATION” software supplied
to enable the input of 21-point nonlinear functional characteristics to the transmitter.
A description of the functions of the KAP communicator is contained in the KAP Communicator Operating
Manual, and information on the Hart/RS232 converter can be found on the Hart/RS232/01 Converter
information sheet.
