Class 2 insulation (double or reinforced insulation)

CAT II Overvoltage category II for measurements on electric and electronic devices connected to the mains

supply with a power plug. This category also covers all smaller categories (e.g. CAT I for measuring

signal and control voltages).

CAT III Overvoltage category III for measuring in building installation (e.g. outlets or sub-distribution). This cat-

egory also covers all smaller categories (e.g. CAT II for measuring electronic devices).

Ground potential

The unauthorised conversion and/or modification of the unit is inadmissible because of safety and approval reasons

(CE).
