Performance Under Operating Conditions

Temperature Stability:

Cold Junction

Compensation

(thermocouple Only):

0.01% of span/￿C change in ambient temperature.

Better than ￿1￿C.

Supply Voltage Influence:	Negligible.
Relative Humidity	Negligible
Influence:
Sensor Resistance	Thermocouple 100￿: <0.1% of span error
Influence:	Thermocouple 1000￿: <0.5% of span error
	RTD Pt100 50￿/lead: <0.5% of span error
