*ACCURACY:
Includes repeatability, temperature
coefficient (18° to 28° C), time stability
(1 year), and linearization conformity
errors. Excludes probe errors; however,
probe errors around 0° C may be compen-
sated by an internal adjustment.
REPEATABILITY:
0.1° C typical for 1 week at constant ambi-
ent temperature.
TEMPERATURE COEFFICIENT:
18° to 28° C; included in accuracy specifica-
tion. From –10° to 18° and 28 ° to 50° C:
less than
