Test procedure
Measure resistance of
Terminal to terminal
1) Open at 170°C (-10/+5°C)
Measure resistance of
terminal to terminal
Measure resistance of
Terminal to terminal
Measure resistance of
therminal to terminal
Measure resistance of
Terminal to terminal
Measure capacitance of
Terminal to terminal
Measure resistance of
Terminal to terminal
Check result
Measure resistance by pressing
button When resistance becomes ∞
Resistance value < 5Ω
