Hello again Mr. wayneh Sir.
Measurements taken using this technique are often inaccurate as a result of the total capacitance of the oscilloscope’s chassis being connected straight to the circuit one is testing at the point where the common lead connects.
I did not mean to open up a can of worms for you or confuse you in any way .Floating a ground-referenced oscilloscope is a dangerously lethal technique I use for “defeating” the oscilloscope’s protective grounding system by disconnecting signal common from the earth by either using an isolation transformer or mitigating the grounding system, which allows certain parts of the oscilloscope — namely the chassis, cabinet, and connectors — to cover the potential of the oscilloscope probe ground lead connection point.Not following. Do you mean failing to connect the ground clip before probing?
