If the resistance of the SPRT is less than the rated resis-
tance, there may be a short in the sensor. Contact an
Authorized Service Center.
If the resistance of the SPRT is only a few ohms, there
may be a short in the four lead-wires. Contact an Autho-
rized Service Center.
If the SPRT is open, the resistance will be "Out of Limits"
or in the kilo-ohm or mega-ohm range. Contact an Au-
