When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use two new AAA batteries of the same type.

6.3 Canvi de fusibles

If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type and rating. To replace the fuse, you will need to open the meter's casing, which should only be done by qualified personnel. Ensure the meter is disconnected from all power sources and test leads before attempting fuse replacement.

7. Solució De Problemes

• Sense pantalla: Comproveu la instal·lació de les piles i assegureu-vos que no estiguin esgotades. Substituïu-les si cal.
• "OL" (Overload) Indication: The measured value exceeds the selected range. For auto-ranging meters, this indicates the value is beyond the meter's maximum capability for that function.
• Lectures inexactes:
  • Ensure test leads are properly connected and not damaged.
  • Comproveu el nivell de bateria; una bateria baixa pot afectar la precisió.
  • Verifiqueu que s'ha seleccionat la funció i l'interval correctes.
  • Ensure proper contact between probes and the circuit.
• La mesura actual no funciona: Check the fuse. If blown, replace it with a fuse of the correct rating.
