NOTES:
(1) Lead resistance effect is given for the condition of not having the NTC thermistor installed in the
backpanel. As a general rule; as long as the lead resistance of the (+) lead matches the parallel
combination of the thermistor and lead resistance in the (X) lead, the given specifications apply.
(2) Output Range and Supply Current specifications are based on minimum output load resistance.
Minimum output load resistance is calculated by V

, where P
E
is the output Effective Available
Power that guarantees output range and accuracy specifications.
(3) Accuracy includes the effects of repeatability, hysteresis, and linearity, but does not include sensor
accuracy.
(4) Nonlinearity is calculated using the best-fit straight line method.
