GND Reference

The ground (0V) reference is shown by a small arrow on the left hand side of the screen. The colour of the arrow matches the colour of the trace display. The default colours are yellow for channel A and magenta for channel B.

   


To adjust the ground reference setting, use the "Gnd" buttons on each channel control panel. Each Gnd reference button will adjust the ground reference for that channel only. The Gnd reference can be changed both in idle mode and in run mode.
