Change the value for a coefficient as follows:
1. Click on the „Coefficients“ bu on.
2. Press the bu on with the desired coefficient

Offset (offset value range: -10°C to +10°C). Once you changed the
offset, „*U“ is displayed behind the selected linearisaon funcon in
the measuring mode. The offset value is added to the measured
temperature value.

W corresponds to the sensor‘s current resistance divided by the sensor‘s resistance at the water
triple point (0,01°C).

If W < 1 and cL1 = 0 (for the range from -190°C to +0,01°C):
In that event the paramter cL1 is bracketed in the selecon: (cL1)
W = aL[W - 1] + bL[W - 1] In W
