8. Consells d'usuari
- Connexió de la sonda: Always ensure test leads are securely connected to the COM and INPUT terminals before taking measurements.
- Understanding Auto-Ranging: The meter automatically selects the appropriate range. If you see "OL" (Overload) on the display, it means the input is out of the current range or the maximum measurable value for that function.
- Mesura de corrent CA: Remember to clamp around only a single conductor for accurate AC current readings. Clamping around multiple wires (e.g., live and neutral together) will result in a zero reading as the magnetic fields cancel out.
- Descàrrega del condensador: Always discharge capacitors before measuring their capacitance to prevent damage to the meter or injury.
