3-2. Temperature Characteristics of Release Voltage
The temperature coefficient ^{Δ + VDET} for the release voltage is calculated by the temperature
ΔTa
coefficient of the detection voltage ^{Δ − VDET} as follows:
ΔTa
Δ + V_{DET =} +V_{DET ×} Δ − V_DET
ΔTa
− V_DET ΔTa
The temperature coefficients for the release voltage and the detection voltage have the same sign
consequently.
3-3. Temperature Characteristics of Hysteresis Voltage
The temperature characteristics for the hysteresis voltage is expressed as ^{Δ + VDET} − ^{Δ − VDET} and is
