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.
