SECTION 6 SPECIFICATIONS
MODEL 865
TEMPERATURE SENSOR TYPE: Thermistor (2252 Ohm @ 77°F)
RANGE TEMPERATURE ACCURACY*
SPAN RESOLUTION 65° TO 82°F; 1 year
200°F – 40.0° to 199.9° 0.1° 6 (0.3% rdg + 0.5°F)
– 70.0° to – 40.1° 0.1° 6 (0.3% rdg + 1.0°F)
300°F – 70° to 300° 1° 6 (0.3% rdg + 1°F)
MODEL 866
TEMPERATURE SENSOR TYPE: Thermistor (2252 Ohm @ 25°C)
RANGE TEMPERATURE ACCURACY*
SPAN RESOLUTION 18˚ TO 28˚F; 1 year
150°F – 40.0° to 150.0° 0.1° 6 (0.3% rdg + 0.3°C)
– 55.0° to – 40.1° 0.1° 6 (0.3% rdg + 0.6°C)
*ACCURACY: Includes repeatability, temperature
coefficient (65° to 82°F), time stability
(1 year), and linearization conformity
errors. Excludes probe errors; how-
ever, probe errors around 32°F may
be compensated by an internal
adjustment.
REPEATABILITY: 0.2°F typical for 1 week at constant
ambient temperature.
TEMPERATURE COEFFIECIENT: 65° to 82°F; included in accuracy
specification. From 14° to 65° and
82° to 122°F: less than 6 (0.06% rdg
+0.01°F)/°F.
SENSOR VOLTAGE: 40 mV RMS maximum.
