5 Troubleshooting
5.1 Troubleshooting
If the SPRT 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 SPRT available.
5.2 Problem Causes and Solutions
a. R0/Rtpw becomes higher significantly. This is likely caused
by mechanical shocks. The SPRT should be annealed to
release the stress of platinum wires and to recover R0/Rtpw
value. Measure R0/Rtpw of the SPRT 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
SPRT may be damaged.
