*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

(0.06% rdg
+0.01°F)/°F.
SENSOR VOLTAGE:
40 mV RMS maximum.
