the product is cheaply made and poorly designed. The switching power supply inside has almost no noise suppression. Mains ground pin connects directly to the secondary side by a AWG28 cable. It can not measure its own signal correct. Feeding 1KHz 50% duty cycle it measures 57,2%. User interface is awful and it always switches on with both channels on. It's a toy, waste os money.

  • davepegz If you look in the system menu you'll find you can set it to start up with 1, 2 1 2 or no channels activated. The mains ground pin actually attaches to an earthing tag and is perfectly ok. The duty cycle measurement is perfect on mine both using an internal channel and an external signal. Are you using it in an electrically noisy environment? I know the dimmer switch on my overhead lights can cause havoc with a lot of test equipment!
