Hi all,
can someone explain in a simple (if possible ) way , how to measure the primary (hot) side of an power supply without burning the scope or the PSU ?
From reading various posts in here I came to the following procedure :
1. Use an isolation transformer on the PSU and then connect the probes ground
on the hot ground on the PSU and the probe wherever I want in the primary side.
OR
2. Use a dual channel scope in add or subtract mode without the need of an isolation transformer, connecting the two probes ground together and probe with the two probe tips the hot side.
I have an old dual channel 25MHz scope who says max input 300V (DC +AC peak) and I want to do this mostly to learn .
thanks in advance for any tips or recommendations.
