2. Informazzjoni dwar is-Sigurtà

Dejjem segwi l-prekawzjonijiet ta' sigurtà li ġejjin biex tevita korriment personali jew ħsara lill-multimetru:

• Do not exceed the maximum input limits for any measurement range.
• 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.
• Dejjem skonnettja l-enerġija miċ-ċirkwit u armi l-kurrent kollu ta' vultaġġ għoli.tagIl-kapaċitaturi e qabel ma twettaq testijiet tar-reżistenza, tal-kontinwità, jew tad-dijodi.
• Ensure the test leads are in good condition, without any damaged insulation.
• Tħaddimx il-multimetru jekk jidher li huwa bil-ħsara jew jekk il-kaxxa tkun miftuħa.
• Use the correct function and range for each measurement.
• Żomm subgħajk wara l-protezzjonijiet tas-swaba' fuq il-probes tat-test waqt il-kejl.
• Do not use the multimeter in wet environments or in the presence of explosive gases or dust.
• Il-Vol Mhux Kuntatttage (NCV) function is for indication only; always verify voltage presence with direct measurement.
