  • Page 4: General Information Regarding The Ce Marking

    General information regarding the CE marking HAMEG instruments fulfill the regulations of the EMC directive. The conformity test made by HAMEG is based on the actual generic- and product standards. In cases where different limit values are applicable, HAMEG applies the severer standard. For emission the limits for residential, commercial and light industry are applied.

  • Page 5: Specifications Hm2005

    The built in RS-232 serial interface permits remote controlled operation by a X-Y phase shift: <3° below 220kHz PC. The outstanding feature of the HM 2005 include a second time base with the Operation / Control ability to magnify, over 1000 times, extremely small portions of the input signal.

    Important hints Important hints The case, chassis and all measuring terminals are connected to the protective earth contact of the appliance inlet. The instrument operates according to Safety Class I (three conductor power cord This oscilloscope is easy to operate. The logical arrangement of with protective earthing conductor and a plug with earthing the controls allows anyone to quickly become familiar with the contact).
