6. 2. Temperature characteristics of release voltage
The temperature change ^{∆ + VDET} of the release voltage is calculated by the temperature
∆Ta
change ^{∆ − VDET} of the detection voltage as follows:
∆Ta
∆ + VDET ₌ +VDET _× ∆ − VDET
∆Ta
− VDET ∆Ta
The temperature changes of the release voltage and the detection voltage consequently have the
same sign.
6. 3. Temperature characteristics of hysteresis voltage
The temperature change of the hysteresis voltage is expressed as ^{∆ + VDET} _− ^{∆ − VDET} and is
∆Ta
∆Ta
calculated as follows:
∆ + V DET _− ∆ − V DET ₌ V HYS _× ∆ − V DET
∆ Ta
∆ Ta
