■ Two-point Input Shift
Use a two-point input shift to output more accurate display values.
Preparations
Refer to the preparations for a one-point input shift.
1. The input value is shifted at two points: near room temperature
2. Use the following formulas to calculate the upper-limit tempera-

near the set point, accuracy can be increased further by using
another point within the measurement temperature range other
than the set value of room temperature.
