If a wrist strap under test indicates a failure, following are possible causes.
1. Check that the wrist strap cable connector is connected properly to the
ST2200. See Figure 1, Item 9 for wrist strap connector location. Do not rely on
common ground of AC line for wrist strap testing.

that the operator's free hand is not in contact with any other object.

over clothing.
