From any terminal to ground

600 V CAT III

Voltage ratings are given as “working voltage”. They should be read as Vac-rms (50-60 Hz) for AC sinewave applications and as Vdc for DC applications.

Overvoltage Category III refers to distribution level and fixed installation circuits inside a building.

The terms ‘Isolated’ or ‘Electrically floating’ are used in this manual to indicate a measurement in which the Test Tool’s Shielded Banana inputs or banana jack is connected to a voltage different from earth ground.

The isolated input connectors have no exposed metal and are fully insulated to protect against electrical shock.

Before use, inspect the test leads for mechanical damage and replace damaged test leads!

Whenever it is likely that safety has been impaired, the Test Tool must be turned off and disconnected from the line power. The matter should then be referred to qualified personnel. Safety is likely to be impaired if, for example, the Test Tool fails to perform the intended measurements or shows visible damage.
