With the sensor at room temperature, check the following resistances between sensor leads:
RED to BLUE = approximately 5 ohms
BLUE to YELLOW = 13.75 ohms · Active Length (inches)
YELLOW to BLACK = approximately 0.7 ohms
RED to BLACK = (RED to BLUE) + (BLUE to YELLOW)
If the indicated conditions do not exist, contact an Authorized AMI Technical Support Representative.
