      I am playing around with connecting a (berd air style) DC brushed motor air pump to one of the heater outputs. I am observing some behviour I did not expect so I wanted to visualize the output of the heater port with my scope. I am still quite new to using bench scopes so I wanted to verify that I am not going to damage my scope by doing this.

      All PSU's in my printer have their V- terminals tied to mains earth and there is a flyback diode connected in parallel with the pump motor.
