Measure the resistance between the terminals.

Resistance

Inspection Terminals	Inspection Conditions	Standard Value
1 - 2	Approx. 20°C {68°F}	2.35 to 2.65 kΩ
1 - 2	Approx. 80°C {176°F}	0.305 to 0.331 kΩ

CAUTION: When the inspection is performed with the sensor immersed in water, be careful not to allow the ingress of water into the terminal part. After inspection is completed, wipe off the water drops from the sensor.
