2 Subject to change without noticeGeneral information regarding the CE markingHAMEG instruments fulfill the regulations of the EMC directive. Theconformity test made by HAMEG is based on the actual generic- andproduct standards. In cases where different limit values are applicable,HAMEG applies the severer standard. For emission the limits forresidential, commercial and light industry are applied. Regarding theimmunity (susceptibility) the limits for industrial environment havebeen used.The measuring- and data lines of the instrument have much influenceon emission and immunity and therefore on meeting the acceptancelimits. For different applications the lines and/or cables used maybe different. For measurement operation the following hints andconditions regarding emission and immunity should be observed:1. Data cablesFor the connection between instrument interfaces and external devices,(computer, printer etc.) sufficiently screened cables must be used.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 andnot be used outside buildings. If an interface has several connectorsonly one connector must have a connection to a cable.Basically interconnections must have a double screening. For IEEE-buspurposes the double screened cables HZ73 and HZ72L from HAMEGare suitable.2. Signal cablesBasically test leads for signal interconnection between test point andinstrument should be as short as possible. Without instruction in themanual for a shorter length, signal lines must be less than 3 metersand not be used outside buildings.Signal lines must screened (coaxial cable - RG58/U). A proper groundconnection is required. In combination with signal generators doublescreened cables (RG223/U, RG214/U) must be used.3. Infl uence on measuring instrumentsUnder the presence of strong high frequency electric or magneticfields, even with careful setup of the measuring equipment, influenceof such signals is unavoidable.Die HAMEG Instruments GmbH bescheinigt die Konformität für das ProduktThe HAMEG Instruments GmbH herewith declares conformity of the productHAMEG Instruments GmbH déclare la conformite du produitBezeichnung / Product name / Designation:OszilloskopOscilloscopeOscilloscopeTyp / Type / Type: HM1008-2mit / with / avec: –Optionen / Options / Options: –mit den folgenden Bestimmungen / with applicable regulations / avec lesdirectives suivantesEMV Richtlinie 89/336/EWG ergänzt durch 91/263/EWG, 92/31/EWGEMC Directive 89/336/EEC amended by 91/263/EWG, 92/31/EECDirective EMC 89/336/CEE amendée par 91/263/EWG, 92/31/CEENiederspannungsrichtlinie 73/23/EWG ergänzt durch 93/68/EWGLow-Voltage Equipment Directive 73/23/EEC amended by 93/68/EECDirective des equipements basse tension 73/23/CEE amendée par 93/68/CEEAngewendete harmonisierte Normen / Harmonized standards applied / Normesharmonisées utilisées:Sicherheit / Safety / Sécurité: EN 61010-1:2001 (IEC 61010-1:2001)Überspannungskategorie / Overvoltage category / Catégorie de surtension: IIVerschmutzungsgrad / Degree of pollution / Degré de pollution: 2Elektromagnetische Verträglichkeit / Electromagnetic compatibility /Compatibilité électromagnétiqueEN 61326-1/A1 Störaussendung / Radiation / Emission:Tabelle / table / tableau 4; Klasse / Class / Classe B.Störfestigkeit / Immunity / Imunitée: Tabelle / table / tableau A1.EN 61000-3-2/A14 Oberschwingungsströme / Harmonic current emissions /Émissions de courant harmonique:Klasse / Class / Classe D.EN 61000-3-3 Spannungsschwankungen u.

Smalldeviations of the measuring value (reading) exceeding the instrumentsspecifications may result from such conditions in individual cases.4. RF immunity of oscilloscopes.4.1 Electromagnetic RF fieldThe influence of electric and magnetic RF fields may become visible(e.g. RF superimposed), if the field intensity is high. In most casesthe coupling into the oscilloscope takes place via the device undertest, mains/line supply, test leads, control cables and/or radiation.The device under test as well as the oscilloscope may be effected bysuch fi elds.Although the interior of the oscilloscope is screened by the cabinet,direct radiation can occur via the CRT gap. As the bandwidth ofeach amplifier stage is higher than the total –3dB bandwidth of theoscilloscope, the influence of RF fields of even higher frequenciesmay be noticeable.4.2 Electrical fast transients / electrostatic dischargeElectrical fast transient signals (burst) may be coupled into theoscilloscope directly via the mains/line supply, or indirectly via testleads and/or control cables. Due to the high trigger and input sensitivityof the oscilloscopes, such normally high signals may effect the triggerunit and/or may become visible on the CRT, which is unavoidable.These effects can also be caused by direct or indirect electrostaticdischarge.HAMEG Instruments GmbHHersteller HAMEG Instruments GmbH KONFORMITÄTSERKLÄRUNGManufacturer Industriestraße 6 DECLARATION OF CONFORMITYFabricant D-63533 Mainhausen DECLARATION DE CONFORMITE |
