Subject to change without notice 25Operating controls of the HM6050-2(1) Artificial HandThis feature simulates the influence of the human hand. Whenperforming EMC measurements for devices, which are held in handduring use (for example: electrical drilling machines, hairdryer etc.) theArtificial Hand simulates the influence of the human hand on the EMCbehavior of the equipment.If the DUT has a plastic housing, a conductive film should be used tocover the housing at the location, where it is held in hand. A test leadis used to connect the film to banana jack 1. DUTs with a metal housingare connected directly to banana jack 1, if they don’t have a protectiveground connection according to Class 1.(2) Ground jackThis jack is used for testing DUTs, which don’t have a protectiveground line in their AC power cable, but do have a separate groundconnection. The DUT’s ground connector has to be linked to bananajack 2 via a test lead. This lead should be placed in parallel to the two-line AC power cable.(3) Mains power outlet for the DUTThe DUT will be connected to the HM6050-2’s Mains power outletwith its AC power cable. The maximum supply current of the DUTmust not exceed a continuous current of 16 A at an ambienttemperature of 23 °C. At higher ambient temperatures a fan has to beused for cooling. In any case a sufficient free air circulation has to bekept for the HM6050-2.(4) LED L1If the mains plug connected in correctly in phase, the LED L1 is lit. Ifit does not, the mains plug has to be turned by 180°. There is no risk
