WARNING!
Risk of injury due
to electric voltage!
If the device is subjected to measurement
voltage surges higher than the permissible
overvoltage category, safety-relevant
insulations in the device can be damaged,
which means that the product’s safety can
no longer be guaranteed.
Only use the device in environments
in which the permissible measurement
voltage surge is not exceeded.
