*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.
Q68TD-G-H02 needs to be powered on 30 minutes prior to operation for compliance to the specification
(accuracy).
*3 Temperature measurement can be executed, but accuracy is not guaranteed.
