N56FU is an application to read, and optionally log, data from a Maplin N56FU digital multimeter with USB interface. It is possible that other multimeters can also be read via this app - I would like to hear from anyone who tries, whether the result is success or failure.

This application should work on any RISC OS computer that has a USB interface, except (currently) the Raspberry Pi. It has been tested on an Iyonix, a BeagleBoard xM and a Risc PC with Simtec USB podule. I hope to make it work with the Raspberry Pi at some point in the future. If you can help, please contact me!
Copy the !N56FU application into a convenient location. I recommend the $.Apps directory.
The applcation does not currently auto-start when a meter is plugged into the USB. If this is an inconvenience, please contact me.
Double-click the !N56FU application. The main window should open. If the N56FU meter is switched on and USB communication has been enabled (hold down the "Rel|USB" button for a couple of seconds), the meter's readings will appear in the main window.
Data logging to file can be toggled on and off, and a logging period chosen.
• First choose a datalog filename and file location by clicking Menu over the main window or the menu bar icon, and move right to "Save as". Modify the file name as you wish and drag the icon to the location where you want the datalog file to be.
• Second, choose the logging period by clicking Menu again and move right to "Logging period". Set the period according to your choice.
• Lastly, click on the play or stop icon at the left side of the main window to start or stop logging. Subsequent starts cause new data to be appended to the existing file.
• If you're running with the Simtec stack and you quit the app, you will have to unplug and re-plug the multimeter before running it again.
