To reduce the risk of electric shock, leakage-current or resistancemeasurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before theappliance is returned to the customer.• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variationsbetween individual instruments or/and units.!
