9.2 IT-R compatibility
An Indicating transmitter can be exchanged for another of the same model, but the current calibration
constants have then to be entered by the keyboard (Section 5.10) as your IT-R has been precalibrated for the
process it was ordered for.
The models PR-03 and PR-01 use the same Indicating transmitter. When the power is switched on, the
microprocessor checks which sensor model is connected, and adapts the software accordingly.
Note: The plug at the sensor end is different for PR-03 and PR-01. All PR-03 models use same electrical
connector and cables.
9.2.1 Upgrading IT-R program version
The program version number consists of two digits. The first digit is the major version, the latter is the
minor version. Programs with the same major versions (i.e the same first number) are compatible. Also
earlier major versions can usually be substituted with later major versions.
K-Patents improves the IT-R programming all the time. If you need a new (or latest) program version,
order the spare part PR-7509. You’ll get a new EPROM (Figure 9.2) with the new program version and you
upgrade by removing the old EPROM from the processor card and inserting the new one into its place.
