PERSONAL PRECAUTIONS ! When using this meter, please observe all normal safety rules concerning: Protection against the dangers of electric current. Protection of the meter against misuse. ! Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, they must be replaced with genuine Sealey leads with the same electronic ratings. Failure to do so will invalidate the warranty. " DO NOT use leads if damaged or if the wire is bared in any way. 1.2. GENERAL SAFETY INSTRUCTIONS ! Familiarise yourself with the application and limitations of the meter as well as the potential hazards. IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN. ! When the meter is linked to a measurement circuit, do not touch unused meter terminals. ! When the scale of the value to be measured is unknown set the selector to the highest range available. ! Before rotating the range selector to change functions, disconnect test leads from the circuit under test. # WARNING! Never perform resistance measurements on live circuits. ! Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe barriers while measuring. ! When not in use, store the meter carefully in a safe, dry, childproof location. Storage temperature range -10OC to 50OC. ! Never apply voltage or current to the meter that exceeds the specified maximum. Layout: ( Refer to fig. 1. ) 1. Large LCD display 2. Max/Min/RS232 Button 3. Relative Button 4.

Only when you are sure that you understand the procedures is it safe to proceed with testing. # WARNING! Risk of electrocution. High voltage circuits, both AC and DC are very dangerous and should be measured with great care. Operating temperature range 0OC to 40OC. Remember to turn on meter before use and to turn it off when measurement is completed. NOTE: IF “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range. NOTE: On some low AC and DC ranges, with the test leads not connected to a device, the reading may show a random fluctuating reading. This is normal and is caused by the high input sensitivity. The reading will stabilise and give a proper measurement when connected to a circuit. 4.1. Mode Button (fig.1.12) 4.1.1. Press the Mode button to toggle between the AC and DC in the voltage & current measurements. 4.2. Range/#CYL Button (fig.1.10) 4.2.1. The range is automatically selected by the meter. 4.2.2.
