English to Spanish Tech/Engineering Engineering (general)

Hola colegas, estoy traduciendo un texto técnico sobre Pruebas de SMPS (Fuente de alimentación conmutada) y no entiendo esta frase: ‘floating’ the scope.

Esta es la oración: Many technicians and engineers attempt to solve this problem by removing the ground connections from the oscilloscope and ‘floating’ the scope.
Mi intento: Muchos técnicos e ingenieros intentan resolver este problema al eliminar las conexiones a tierra del osciloscopio y...

Aquí más contexto:

Line isolation
A single-phase AC line has a hot and a neutral lead.
The neutral lead is tied to ground in the distribution system but may still be several volts above ground at the power supply.
The result is that there is no ground reference on the primary section of the supply.
Connecting a grounded oscilloscope probe to any point in the primary circuit can result in a short circuit.
Many technicians and engineers attempt to solve this problem by removing the ground connections from the oscilloscope and ‘floating’ the scope.
This is an extremely dangerous practice because it could leave the oscilloscope case at several hundred volts above ground.
Anyone touching the scope case could be electrocuted.
An alternative to floating the scope is to use an isolation transformer, wired as shown in Figure 2.
This separates the supply being tested from the AC line.

Les agradezco su colaboración.
