Hand-held Analyzer Types 2250 and 2270 – User Manual

9.2.3 Downgrade to an Earlier Version

It is possible to downgrade to an earlier version of the software:

1) Change the “latest” part of the server address (see Fig.9.2) to the requested software

package, for example, “SW22”

2) Press Check for updates.

3) Follow the procedure described in section 9.2.1 or section 9.2.2.

Note: Only software packages equal to or above SW24 can downgrade to another package.

Software packages down to SW21 are available for update through Internet.

9.3 How to Move a License

If you have more than one analyzer, you may want to share application software between the

analyzers. You can do this by moving the license from one analyzer to another by using

Measurement Partner Suite BZ-5503, together with the License Mover VP-0647.

If you lend out your analyzer, you may want to temporarily ‘un-install’ applications not needed.

This can be achieved by moving the license of the application to License Mover VP-0647. When

needed again, you move the license back to your analyzer.

Please consult the on-line help included with the BZ-5503 software for instructions on how to

move a license.
