1. The Lin and Null ranges are general purpose ranges that
may be configured for any required span and zero. Both
ranges provide a linear relationship between input and
display. The Lin range is unipolar while the Null range is
bipolar.
2. The iTC includes two curves for 27 Ohm Rhodium/Iron
sensors. Curve A is used for sensors having a resistance of
2 Ohms or greater at 4.2K. Curve B is used for sensors
having a resistance of less than 2 Ohms at 4.2K. Using the
appropriate curve should produce linearisation errors of
less than 1% over the full temperature range. For a more
accurate fit to a specific sensor, order a custom calibration.
3. This is for a pure platinum element.
