CASMED 740 MONITOR SERVICE MANUAL21-02-0174 REV. 02 05/08254. DECLARATION OF CONFORMITYManufacturers Declaration of ConformityElectronic Emissions and ImmunityThe Model 740 Monitor is intended for use in the electromagnetic environment specified below. Thecustomer or the user of the Model 740 Monitor should assure it is used in such an environment.Emissions Test Compliance Electromagnetic EnvironmentRF emissions – CISPR 11 Group 1 The Model 740 Monitor uses RF energy only for its internalfunction. Therefore, its RF emissions are very low and arenot likely to cause any interference in nearby electronicequipment.RF emissions – CISPR 11 Class BHarmonic emissionsIEC 61000-3-2 Class BVoltage fluctuations /flicker emissionsCompliesThe Model 740 Monitor is suitable for use in allestablishments, including domestic establishments andthose directly connected to the public low-voltage powersupply network that supplies buildings used for domesticpurposes.Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic EnvironmentGuidanceElectrostaticdischarge (ESD)IEC 61000-4-2+/- 6 kV contact+/- 8 kV air+/- 6 kV contact+/- 8 kV airFloors should be wood concreteor ceramic tile. If floors arecovered with synthetic material,the relative humidity should be atleast 30%.Electrical fasttransient/burstIEC 61000-4-4+/- 2 kV for powersupply lines+/- 1 kV forinput/output lines+/- 2 kV for powersupply lines+/- 1 kV forinput/output linesMains power quality should bethat of a typical commercial orhospital environment.SurgeIEC 61000-4-5+/- 1 kV differentialmode+/- 2 kV commonmode+/- 1 kV differentialmode+/- 2 kV commonmodeMains power quality should bethat of a typical commercial orhospital environment.Voltage Dips,short interruptionsand voltagevariations onpower supplyinput linesIEC 61000-4-11< 5% UT (>95% dip inUT ) for 0.5 cycle.40% UT (60% dip inUT ) for 5 cycles.70% UT (30% dip inUT ) for 25 cycles.< 5% UT (> 95% dip inUT ) for 5 seconds.< 5% UT (>95% dip inUT ) for 0.5 cycle.40% UT (60% dip inUT ) for 5 cycles.70% UT (30% dip inUT ) for 25 cycles.< 5% UT (> 95% dip inUT ) for 5 seconds.Mains power quality should bethat of a typical commercial orhospital environment. If user ofthe Model 740 Monitor requirescontinued operation during powermains interruptions, it isrecommended that the Model 740Monitor be powered from anuninterruptible power supply or abattery.Power frequency(50/60 Hz)magnetic fieldIEC 61000-4-83 A/m 3 A/m Power frequency magnetic fieldsshould be at levels characteristicof a typical location in a typicalcommercial or hospitalenvironment.NOTE: UT is the A.C. mains voltage prior to application of the test level. |
