Thermistor Channels
Refer to Table 3-7 to configure a thermistor channel. The R(T) polynomial type requires
polynomial coefficients to be entered. The thermistor characterization polynomial is as
follows:
15 . 273
1
+
=
t
x
3 2
3 2 1 0 x B x B x B B y
+ + + =
y R exp
=
Where t is the temperature in °C and R is the resistance in Ω . Any coefficients that are
not used must be set to 0.
