2. Informació de seguretat

Always observe basic safety precautions when using this multimeter to avoid personal injury or damage to the meter or equipment under test. Read the following safety information carefully before use.

• No supereu el volum màximtage rating specified for any function.
• Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
• Desconnecteu sempre els cables de prova del circuit abans de canviar les funcions.
• Assegureu-vos que el mesurador estigui en la funció i el rang correctes per a la mesura.
• Inspeccioneu els cables de prova per detectar danys a l'aïllament o metall exposat abans d'utilitzar-los. Substituïu-los si estan danyats.
• No feu funcionar el mesurador si sembla danyat o si la carcassa està oberta.
• Traieu les piles si el mesurador no s'utilitza durant un període llarg.

5. Configuració

5.1 Instal·lació de la bateria

The multimeter requires two 1.5V AAA batteries (not included) for operation. To install or replace batteries:

1. Assegureu-vos que el multímetre estigui apagat i desconnecteu tots els cables de prova.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior de la unitat.
3. Utilitzeu un tornavís per obrir el compartiment de la bateria.
4. Introduïu dues piles AAA, observant la polaritat correcta (+/-) tal com s'indica a l'interior del compartiment.
5. Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

5.2 Connexió dels cables de prova

Proper connection of test leads is crucial for accurate and safe measurements.

• Insert the black test lead into the 'COM' (Common) input jack.
• Insert the red test lead into the 'VΩHz' input jack for voltage, resistance, frequency, and diode measurements.
• For current measurements (mA/A), insert the red test lead into the 'A mA' input jack. For microampere measurements (uA), insert the red test lead into the 'uA' input jack.
