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.

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.
