Your MercuryiTC may not have all the above calibration files pre-loaded.
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 linearization 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.
4
This is for a platinum element that is ballasted to BS1904/DIN43760. This element is more readily available than a pure platinum
element but its performance is unspecified below 73K. The data for 50-70K is based on BS1904:964 rather than BS1904:1984.
