AM1620 Precision Industrial PRT User's Guide

5 Troubleshooting

5.1 Troubleshooting

If the probe appears to function 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 probe available.

5.2 Problem Causes and Solutions

a. Data changes greater than 0.1°C. This is likely cause by

mechanical shocks. Measure the R0 of the probe to verify.

b. Data unstable at the Ice Point (R0). This is likely cause by bad

connections. If the connector appears to be in good condition

and the connections are good, the PRT may be damaged.

c. Data unstable at high temperatures. It is likely caused by

electrical noise in the system. Reduce the temperature and

observe the data. If it is stable, electrical noise is interfering with

the measurements at high temperatures. Use a ground wire to

reduce the electrical noises.
