2. Informazzjoni dwar is-Sigurtà

Always observe safety precautions when using electrical testing equipment. Failure to do so may result in injury or damage to the meter or equipment under test.

• Ensure the meter is in good working condition and test leads are not damaged before use.
• Applikax voltage or current that exceeds the maximum rated limits for the meter.
• Always disconnect power to the circuit under test before measuring resistance, capacitance, or continuity.
• Oqgħod attent meta taħdem bil-volumtages 'il fuq minn 60V DC jew 30V AC RMS, għax dawn joħolqu periklu ta' xokk elettriku.
• Ibdel il-batterija meta jidher l-indikatur ta' batterija baxxa biex tiżgura qari preċiż.
• Do not operate the meter in explosive atmospheres.
• Use the correct input terminals and range for your measurement.
