The terminals for connecting current and voltage clamps are not isolated from the measurement terminals. If the DET2/3 is used in a CAT IV 300 V environment, the clamps and their measurement leads must be rated the same or higher. Only the Megger MCC1010 and Megger MVC1010 are sufficiently rated, no other clamps are to be used. -
