If you encounter a problem

✔Inspect the connectors on the load, open, short, and through standards and the connectors on the bias networks and the semi- rigid cables.

✔Clean the connectors if necessary. See step 2 in the section titled “To enhance measurement accuracy" on page 112.

✔If connectors are damaged, replace the standard or cable.

✔Ensure that the standards meet their published specifications.
