Installation Category II – 600V and Category III – 300V. It is
recommended for use with local level power distribution,
appliances, portable equipment, etc, where only smaller transient
overvoltages may occur, and not for primary supply lines, overhead
lines and cable systems.
■
Do not exceed the maximum overload
limits per function (see specifications) nor the limits marked on the
instrument itself. Never apply more than 600VDC between the test
lead and earth ground.
