Procedure,
Cont.
10.
If either of the measured values are outside of range, remove
power and replace Termination Board Connector Cable
(1801415-xxx).
11.
Return power and perform steps 9 and 10. If either of the
measured values are outside of range, remove power and
replace Termination Board (2101873-xxx).
12.
Return power and perform steps 9 and 10. If either of the
measured values are outside of the range, remove power and
replace Main Processor Board (2101471-xxx) and EXIMV
(2101465-xxx).
RTD Impedance Test
If readings from the RTD are still suspect following the RTD Probe test, follow the
Instructions below to test the current source on the Termination Board to verify it is
receiving power.

Instructions
Step Procedure
1.
Immerse RTD Probe in ice bath.
2.
Perform a Continuity check between any two similar color wires.
Measured resistance should be 1 OHM or less.
3.
Perform a Continuity check between any two dissimilar color
wires. Measured resistance should be approximately 100 Ohms.
4.
Perform a Continuity check between shield wire and any other
wires. Measured resistance should be in the Megohm range.
5.
If any values are returned out of range, RTD Probe is defective.
Replace RTD.
