precautions.
International symbols used on the Meter and in this manual
are explained in chapter 1.2.
1.1 Precautions safety measures
1.1.1 Preliminary
* As the possibilities of high transient overvoltages occurred
in today’s power systems increase, more stringent safety
standards are set for the electrical test equipment. Transients
on electrical systems(power grid, feeder or branch circuits)
will trigger a series of incidents that may result in serious
personal injury. To protect you against transients, safty must
be built into the test equipment.
