100 Ohm RTD 

Failure of the 100 Ohm RTD will be indicated with an error message on the analyser screen.  If 
the 100 Ohm RTD has failed, replace the RTD and cable assembly (Severn Trent Services part 
number 11713 or 51-1008) (Refer to Figure 2 and Figure 4; 18). 

The following is a summary of the ohm/temperature equivalence:
