Fluke 125 Users Manual Max. Input Voltages Input A and B directly 600 V CAT III Input A and B via BB120 300 V CAT III Input A and B via STL120 600 V CAT III Max. Floating Voltage 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 sine wave applications and as Vdc for DC applications. Measurement 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. If Safety Features are Impaired Use of the Test Tool in a manner not specified may impair the protection provided by the equipment. 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. 0-6

Voltage ratings are given as “working voltage”. They
should be read as Vac-rms (50-60 Hz) for AC sine
wave applications and as Vdc for DC applications.
Measurement 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.
If Safety Features are Impaired
Use of the Test Tool in a manner not specified may
impair the protection provided by the equipment.
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.
