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/
℃
Note3) Measuring the temp. is available, but accuracy and resolution is not guaranteed.
(1) When ambient temp. is normal (25 ± 5
℃
): within the ±0.2% range of measurement temp.
(2) When ambient temp. is operating temp. (0 ~ 55
℃
): within the ±0.5% range of measurement temp.
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 0.2 %] - 1 ~ 1000
℃
+ [{1300 - (-200)} x 0.2 %] + 1
namely, 996.0 ~ 1004.0 [
℃
].
(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.
