2-2. Temperature Characteristics of Release Voltage
The temperature coefficient ^{∆ + VDET} for the release voltage is calculated by the temperature coefficient
∆Ta
∆ − VDET _{of the detection voltage as follows:}
∆Ta
∆ + VDET ₌ +VDET _× ∆ − VDET
∆Ta
− VDET ∆Ta
The temperature coefficients for the release voltage and the detection voltage have the same sign
consequently.
