Note:
1. The module is calibrated per:
IEC Publication 751 for platinum RTDs: 100Ω @ 0 degrees C, TCR (α) =
0.00385Ω/Ω/degrees C.
DIN 43760 for nickel RTDs
American Platinum RTDs: 100Ω @ 0 degrees C, TCR (α) = 0.00392Ω/Ω/
degrees C
2. Terminals labeled shield are not connected internally. Shields should be
grounded at the field device end.
3. When using 2-wire configurations, the temperature equivalent of twice the
lead resistance of one leg must be subtracted from the temperature reading.
