AT16 DI 16A 3-Phase Current Adapters Devices which are equipped with a 5-pole, 16 A / 6 h CEE plug can be quickly and efficiently tested with the AT16-DI CEE adapter. Connect the adapter to a test instrument designed for testing portable devices in accordance with DIN VDE 0701-0702 in order to perform testing per DIN VDE 0750/IEC 601, which is equipped with an earthing contact outlet for connecting the device under test, and is capable of directly measuring protective conductor current. The following tests can be performed on devices with CEE plugs with the help of the AT16-DI CEE adapter: Testing of protective conductor continuity Insulation test Equivalent leakage current measurement Differential current measurement, L1-L2-L3-N Function test
