Note1) Total accuracy (normal temp.) = accuracy (normal temp.) + cold junction compensation accuracy
= ±(full scale X 0.2% + 1.0℃)
Cold junction compensation accuracy = ±1.0℃
Note2) Temp. coefficient: ±100 ppm/℃
(1) When ambient temp. is normal (25 ± 5℃): within the ±1% of entire measurement temp. range
(2) When ambient temp. is operating temp. (0 ~ 55℃): within the ±1% of measurement temp. range
Ex.) When K type thermocouple is used and ambient temperature is normal.
In case of measuring 1000℃ temperature, output range of conversion data is
1000℃ - [{1300 - (-200)} x 1 %] - 1 ~ 1000℃ + [{1300 - (-200)} x 1%] + 1
namely, 984.0 ~ 1016.0 [℃] 입니다.
(1) For stabilization of measurement temperature, warming-up time more than 15 min. is necessary, after
restart.
(2) If ambient temperature changes rapidly, measurement temperature may change temporally. Keep the
ambient temperature steady for stabilization of measuring temperature.
(3) If wind of the cooling pan contacts with module directly in the panel, accuracy decreases. Do not
contact with wind directly.
