*1: If a value entered from the thermocouple is outside the measured temperature range given in the table, it is
handled as the maximum/minimum value of the measured temperature range.
*2: The accuracies only in the temperature ranges of Class 1 to 3 (shaded areas) in JIS C1602-1995 apply.
*3: Temperature measurement can be made, but accuracy is not guaranteed.
