Sensor Input Accuracy

The controller's internal sensor inputs support both 10 K NTC Ω and 20 K NTC Ω sensors. The following table lists
the typical minimum accuracies of the hardware and software for these temperature sensors.
Range
-58 °F to -4 °F (-50 °C to -20 °C)
-4 °F to +32 °F (-20 °C to 0 °C)
32 °F to 86 °F (0 °C to 30 °C)
86 °F to 158 °F (30 °C to 70 °C)
158 °F to 212 °F (70 °C to 100 °C)
212 °F to 266 °F (100 °C to 130 °C)
266 °F to 302 °F (130 °C to 150 °C)
10 k NTC Ω specified for -22 °F to 212 °F (-30 °C to +100 °C) only.
302 °F to 752 °F (150 °C to 400 °C)

b)
NI1000TK5000 specified for -22 °F to +266 °F (-30 °C to +130 °C) only.
NOTE:
This is the accuracy of the internal sensor input (hardware + software [linearization]) only. This table does not
include the characteristics of the sensors themselves, see Sensor Characteristics on page 42.
