English User Manual for the XJW01 LCR Bridge

I have spent a lot of time testing, experimenting and then writing this User Manual. I hope it is useful to the owners of this very useful XJW01 Bridge which comes in two case styles (as a kit or ready-made).

Type 2 Mains powered

Type 1 for external power source

Many owners have had difficulties with these, mainly because if you press the wrong button you can destroy all the preset calibration values without warning! With one button press, you can also overwrite the factory preset calibration values. This manual explains how to avoid this pitfall and other gotchas!

Once you understand how to use it, it is a very useful piece of kit.

You can now download my PDF manual from here for a modest fee.

The PDF also includes an example front panel template with the correct (or at least more easily understood) button labels.
