Connect input and output IEC leads and apply power. The switch on the box controls output power to the load. After the Raspberry Pi has booted, a launcher should appear on the screen from where you can start the application.
The machine will start in a waveform capture and display mode. You can display up to four different time-correlated waveforms: voltage, current, power and earth leakage current. The selection of waveforms and the vertical and horizontal scales are available on the 'Horizontal' and 'Vertical' controls.
If you want to freeze the image on the display, use the 'Start/Stop' button.
To change the waveform alignment/trigger point, use the 'Trigger' button. You can also disable the trigger entirely by selecting 'Free run'.
