2. Informazzjoni dwar is-Sigurtà

WARNING: Read all safety warnings and instructions before using this product. Failure to follow the warnings and instructions may result in electric shock, fire, or serious injury.

• Always ensure the multimeter is in the correct function mode before connecting test leads to a circuit.
• Do not exceed the maximum input values specified for each range. Maximum voltage between measurement terminal and ground is 600V DC or 600V AC.
• Oqgħod attent ħafna meta taħdem bil-voltag'il fuq minn 30V AC RMS, 42V peak, jew 60V DC. Dawn il-volumitages joħolqu periklu ta' xokk.
• Spezzjona l-wajers tat-test għal insulazzjoni bil-ħsara jew metall espost qabel l-użu. Ibdel jekk bil-ħsara.
• Do not operate the multimeter if it appears damaged or if the battery cover is not properly closed.
• Neħħi l-wajers tat-test miċ-ċirkwit qabel ma tbiddel il-funzjonijiet.
• Replace batteries immediately when the low battery indicator appears on the display.
• Do not use the multimeter in explosive atmospheres.
