70...200 MHz Digital Oscilloscope HMO Series 72x...202x Manual EnglishGeneral information regarding the CE marking General information regarding the CE marking The instruments fulfill the regulations of the EMC directive. The conformity test based on the actual generic- and product standards. In cases where different limit values are applicable, the instrument applies the severer standard. For emission the limits for residential, KONFORMITTSERKLRUNG commercial and light industry are applied. Regarding the immunity DECLARATION OF CONFORMITY (susceptibility) the limits for industrial environment have been used. DECLARATION DE CONFORMITE The measuring- and data lines of the instrument have much influence on emission and immunity and therefore on meeting the acceptance limits. For different applications the lines and/or cables used may Hersteller HAMEG Instruments GmbH be different. For measurement operation the following hints and Manufacturer Industriestrae 6 conditions regarding emission and immunity should be observed: Fabricant D-63533 Mainhausen Die HAMEG Instruments GmbH bescheinigt die Konformitt fr das 1. Data cables Produkt For the connection between instrument interfaces and external devices, The HAMEG Instruments GmbH declares conformity of the product (computer, printer etc.) sufficiently screened cables must be used. HAMEG Instruments GmbH dclare la conformite du produit Without a special instruction in the manual for a reduced cable length, the maximum cable length of a dataline must be less than 3 meters and Bezeichnung: Oszilloskop not be used outside buildings. If an interface has several connectors Product name: Oscilloscope Designation: Oscilloscope only one connector must have a connection to a cable. Typ / Type / Type: HMO722/-24, HMO1022/-24, Basically interconnections must have a double screening. HMO1522/-24, HMO2022/-24 2. Signal cables mit / with / avec: HO720 Basically test leads for signal interconnection between test point and instrument should be as short as possible. Without instruction in the Optionen / Options / Options: HO730, HO740 manual for a shorter length, signal lines must be less than 3 meters mit den folgenden Bestimmungen / with applicable regulations / avec and not be used outside buildings. les directives suivantes Signal lines must screened (coaxial cable - RG58/U).
