5.6 Factory calibration of transmitter
The transmitters are delivered with a factory configuration Pt100 (α=0.00385), 4-wire connection
0...+100°C / +32...+212°F or configured according to customer's requirements. For detailed
information refer to
Factory settings for configuration on page 27.
Due to the long-term drift of max. ±0.01°C or ±0.01% of span per year, a re-calibration of the
transmitter is normally not needed. Should you for any reason require the re-calibration, the
transmitter must be returned to the factory.
