I will always recommend differential probes over an isolation transformer. Why? Using differential probes is very straightforward and uses an unaltered circuit topology, where the risks are easy enough to understand. An isolation transformer changes that topology which can introduce risks that are not easily identifiable and can cause catastrophic failure and/or potentially lethal situations. |

The best option will depend on use case - but my comment was directed at the simple either/or choice so often discussed - especially in regard to safety. In short, you are far less likely to damage equipment or cause injury with differential probes than with an isolation transformer. |

You shouldn´t use an isolating transformer on devices which got a protective earth connection( 3pole mains connection). This is electronics basic knowledge, if someone don´t know this, he should keep his fingers away from mains powered devices in general. |
