6 SymbolDescriptionGeneral hazardDangerous voltageToxic hazardHot surfaceGeneral conditions of useThis product is designed and tested to comply with the requirements of IEC/EN61010-1 Safetyrequirements for electrical equipment for measurement, control and laboratory use , for Class Iportable equipment and is for use in a pollution degree 2 environment. The equipment is designedto operate from an installation category I or II should be protected from the ingress of liquids and precipitation such as rain, snow, moving the equipment from a cold to a hot environment, it is important to allow thetemperature of the equipment to stabilise before it is connected to the supply to avoid condensationforming.

7 The equipment must only be operated within the environmental conditions specified inChapter 1 Performance data , otherwise the protection provided by the equipment may product is not approved for use in hazardous atmospheres or medical applications. If theequipment is to be used in a safety-related application, avionics or military applications, thesuitability of the product must be assessed and approved for use by a competent Electrical hazards (AC supply voltage)This equipment conforms with IEC Safety Class I, meaning that it is provided with a protectivegrounding lead.

8 To maintain this protection the supply lead must always be connected to thesource of supply via a socket with a grounded aware that the supply filter contains capacitors that may remain charged after the equipment isdisconnected from the supply. Although the stored energy is within the approved safetyrequirements, a slight shock may be felt if the plug pins are touched immediately after not remove covers, no user serviceable parts inside. See list of IFR Ltd International ServiceCentres at rear of that the internal supply fuse is in series with the live conductor of the supply lead.

9 Ifconnection is made to a 2-pin unpolarized supply socket, it is possible for the fuse to becometransposed to the neutral conductor, in which case, parts of the equipment could remain at supplypotential even after the fuse has Fire hazardMake sure that only fuses of the correct rating and type are used for an integrally fused plug is used on the supply lead, ensure that the fuse rating is commensuratewith the current requirements of this equipment. See under Performance Data in Chapter 1 forpower Toxic hazardsSome of the components used in this equipment may include resins and other materials which giveoff toxic fumes if incinerated.

10 Take appropriate precautions, therefore, in the disposal of LithiumA Lithium battery (or a Lithium battery contained within an IC) is used in this equipment:As Lithium is a toxic substance, the battery should in no circumstances be crushed, incinerated ordisposed of in normal not attempt to recharge this type of battery. Do not short circuit or force discharge since thismight cause the battery to vent, overheat or Beryllium copperSome mechanical components within this instrument are manufactured from beryllium is an alloy with a beryllium content of approximately 5%.
