u Temperature compensation table by adjustment value (difference value against current temperature)
Ex) If changing compensation resistance at a cold storage room (RCR1) from 10 kΩ (current resistance) to 18 kΩ
(modified resistance), temperature at the cold storage will increase by +1°C.
Ex) Now (R)J1= , (R)J2=1.2kΩ, RCRI=5.6kΩ want to compensate -2°C for Freezing room temperature and
+2°C for Cold storage room temperature
(R)J1 = 12kΩ 1kΩ
(R)J2 = 12kΩ
RCRI = 5.6kΩ 18kΩ
