2. Informazzjoni dwar is-Sigurtà

To ensure safe operation and avoid damage to the meter, please read this manual carefully before use. Adhere to all safety warnings and precautions.

• Always ensure the test leads are correctly connected to the appropriate input terminals for the measurement being performed.
• Do not exceed the maximum input limits for any function. The OW18B is rated for 1000V CAT III and 600V CAT IV.
• 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.
• Qabel ma tkejjel il-kurrent, kun żgur li ċ-ċirkwit ma jkollux l-enerġija u li l-miter ikun imqabbad f'serje mat-tagħbija.
• Ibdel il-batterija immedjatament meta jidher l-indikatur ta' batterija baxxa biex tiżgura qari preċiż.
• Tħaddimx il-miter jekk jidher li għandu l-ħsara jew jekk il-kaxxa tkun miftuħa.
• Use only specified replacement parts when servicing the meter.
• Żomm subgħajk wara l-ostakli tas-sonda waqt il-kejl.
