Whenever the instrument is connected to the
power line during internal troubleshooting,
it
should
be
connected through a line isolation
transformer. This protects the operator from
a possible shock hazard from the instrument
floating power-line system, and protects the
instrument from damage should the test in-
strument earth ground
be
connected to the
213
power line connection.
