2. Informazzjoni dwar is-Sigurtà

Dejjem osserva l-prekawzjonijiet ta' sigurtà meta tuża tagħmir għall-ittestjar elettriku. Jekk tonqos milli tagħmel dan, tista' tikkawża korriment jew ħsara lill-miter jew lit-tagħmir li jkun qed jiġi ttestjat.

• Teċċedix il-valuri massimi tad-dħul għal kwalunkwe funzjoni.
• Uża kawtela kbira 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.
• Inspect test leads for damaged insulation or exposed metal. Replace if damaged.
• Ensure the function switch is in the correct position for the desired measurement before connecting the test leads to the circuit.
• Tħaddimx il-miter jekk jidher li għandu l-ħsara jew jekk il-kaxxa tkun miftuħa.
• Remove test leads from the meter before opening the battery cover.

5. Istruzzjonijiet Operattivi

Before making any measurement, ensure the test leads are correctly inserted into the appropriate input jacks and the rotary switch is set to the desired function.

5.1 Volt DC / ACtage Kejl

• Insert the red test lead into the VΩmA jack and the black test lead into the COM jack.
• Dawwar is-swiċċ li jdur għall- V~ (Volum ACtage) jew V- (DC Voltage) pożizzjoni. Il-miter se jaġġusta l-firxa awtomatikament.
• Qabbad il-wajers tat-test b'mod parallel maċ-ċirkwit jew il-komponent li tixtieq tkejjel.
• Aqra l-voltage valur fuq il-wiri LCD.

5.2 DC/AC Current Measurement

• For currents up to 400mA, insert the red test lead into the VΩmA jack. For currents up to 10A, insert the red test lead into the 10A jack. Insert the black test lead into the COM jack.
• Dawwar is-swiċċ li jdur għall- mA~ (Kurrent AC) jew mA- (DC Current) position. Use the FUNC button to switch between AC and DC if needed.
• Disconnect power to the circuit. Open the circuit where you want to measure current.
• Qabbad il-multimetru f'serje maċ-ċirkwit.
• Applika l-enerġija liċ-ċirkwit u aqra l-valur tal-kurrent fuq id-displej LCD.
• Caution: Never connect the multimeter in parallel to a voltagsors elettroniku meta tkejjel il-kurrent, għax dan jista' jaħraq il-fjus jew jagħmel ħsara lill-miter.

5.3 Kejl tar-Reżistenza

• Insert the red test lead into the VΩmA jack and the black test lead into the COM jack.
• Dawwar is-swiċċ li jdur għall- Ω pożizzjoni.
• Ensure the circuit or component is de-energized and discharged.
