Retain for future reference.2.1 Warnings, Cautions and NotesThis user guide follows the internationally recognised definition. These instructions must be adhered to at all times. DescriptionWARNING : Indicates a potentially dangerous situation which, if ignored, could lead to death, serious injury or health problems. CAUTION : Indicates a situation which could lead to damage of the equipment or environmentNOTE : Indicates important instructions to be followed to perform the relevant process safely and efficiently.2.2 Safety warnings Users of this instrument and their employers must do a valid risk assessment of all electrical work to identify potential sources of electrical danger and risk of electrical injury and must conform to national safety legislation. Where assessment shows significant risk from high energy systems, the use of fused leads must be considered. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired. The instrument must not be used if any part of it is damaged. Use only Megger approved test leads and accessories with this instrument. Test leads and probes must be in good order, clean and have no broken or cracked insulation. Hold the test probes behind the finger-guards when they are in contact. Always check that the correct instrument connections and range selection have been made before connection to the test subject. Voltage or current that exceeds the instrument ratings can damage the instrument and present a shock or fire hazard. Use caution when working with voltages above 30 V AC rms, 42 V AC peak or 60 V DC. These voltages present a shock hazard. To avoid the risk of electric shock do not connect the thermocouple to circuits greater than 10 V. Before any resistance, continuity, diode, or capacitance measurements are started, circuits must be de-energised and isolated from the mains power. Before and after use always test a known voltage to check for correct instrument operation. Do not use the instrument if incorrect results are obtained. Make sure that the test probes are disconnected before the case or battery cover is opened. Replacement fuses must be of the correct type and rating. The instrument must not be used in wet conditions. If it should become wet, it must be dried thoroughly before use.
