• No reading or 'OL' displayed: Ensure test leads are properly connected and making good contact. For current measurements, ensure only one conductor is within the clamp jaw. For resistance/continuity, ensure the circuit is de-energized. 'OL' (Overload) indicates the measured value is beyond the meter's range.
• Unøjagtige aflæsninger: Check battery level. Ensure the correct function is selected. For DC current, use the 'ΔZERO' function.
• Buzzer not sounding in continuity mode: The resistance may be too high (above 50Ω), or the circuit is open.
