If
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.
