RTD Interface Information
A three-wire platinum RTD per DIN 43760 is sup-
ported. The temperature, T, in degrees Celsius is
calculated using the Resistance vs. Temperature
Tables according to the DIN EN 60751 standard for
Class A & B RTDs. The DIN EN 60751 equation is:
R(t) = R
0
* (1 + At +Bt
2
)
Where:
A = 3.9083 * 10

B = -5.775 * 10

= 100ohms
In addition, the user may enter the R
0
, A, and B
coefcients of a custom calibrated RTD, another
platinum standard or a different material (Nickel,
Balco or Copper).
During the RTD calibration, the user will be able to
set the coefcients, restore the factory default for
these coefcients, and calibrate the internal Refer-
ence resistor.
