tools…
Provided that the circuit is at least 10m apart from a CAT III- or 20m apart from a CAT IV-environment.
Pollution degree
Pollution degree 2: Only nonconductive pollution occurs.
Occasionally, temporary conductivity caused by condensation is to be expected. (home and ofce environments
fall under this category).

• When carrying out measurements on a TV set or switching power circuits, always remember that the meter
may be damaged by high amplitude voltage pulses at test points.
• Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your ngers behind the
probe barriers at all times during measurement.
• Use a measuring probe with an insulated connector when measuring voltages exceeding 30V.
• For X10 probe: match the frequency response to the oscilloscope input by adjusting the compensation trim-
