Troubleshooting Network Analyzer Impedance Measurement

[gremio594]

In class we are learning to use Network Analyzers. I am trying to measure impedance on with it but the analyzer is not displaying the point right. I'm measuring a 100 ohm resister and the point is way to the right on the smith chart, like not even on the smith chart. My professor doesn't know how to fix this any ideas?

Thanks for the help guy but I figured it out. Had to hit preset then had to redo the cal
