90
) Conversion
EDIT SPRT 01
PROBE SER#: 1
CONVERSION: W(T90)
RTPW: 25.412294
The W(T90) conversion displays the measurement in ITS-90 W(T
90
)values
rather than temperature. The one user-defined parameter for the W(T
90
)conver
-
sion is the triple point of water resistance, RTPW.

fications. Only subrange 4 is implemented for temperatures below zero. The
user-defined parameters for the IPTS-68 conversion are R0 (R

), and SCALE. The SCALE parameter deter
-
mines whether the temperature values conform to IPTS-68 or ITS-90.
