Note:

If you use an adapter for the connection to the PC, make sure it is designed for this purpose and, thus, has all nine pins accessible. Some 25-to-9 pin adapters are supplied for specific use, such as a mouse, and these may have only certain pins available.

It is not necessary to keep the PC connected to the instrument during measurement. This connection is required for downloading stored measurements, real-time monitoring, reviewing and changing configuration parameters and testing the instrument from the PC (see “Troubleshooting” on page 38 for details).
