5 Troubleshooting
5.1 Troubleshooting
If the PRT functions abnormally, it could be caused by several
possible problem conditions that are described in this section. Try the
solutions recommended and if the problems are still not solved,
contact manufacture for warranty or repair service. Be sure to have the
model number and serial number of your PRT available.
5.2 Problem Causes and Solutions
a. R0/Rtpw becomes higher significantly. This is likely caused by
mechanical shocks. The PRT should be annealed to release the
stress of platinum wires and to recover R0/Rtpw value. Measure
R0/Rtpw of the PRT after annealing to verify.
b. R0/Rtpw unstable during the measurement. This is likely caused
either by bad connections or sensor coils short. Check the
connections first and if the connections are good, the PRT may
be damaged.
