7 Issolvi l-problemi

If the multimeter is not functioning as expected, try the following common troubleshooting steps:

• Ebda Wiri/Wiri Dgħajjef: Iċċekkja l-livelli tal-batteriji u ibdelhom jekk meħtieġ. Kun żgur li l-batteriji jiddaħħlu bil-polarità korretta.
• Qari Skorrett: Verify that the correct function and range are selected. Check test leads for damage or poor connection. Ensure the circuit is properly de-energized for resistance/continuity tests.
• Ebda Ħoss ta' Kontinwità: Check if the continuity function is selected. Ensure test leads are making good contact.
• Current Measurement Failure: Check and replace the fuse if blown. Ensure the multimeter is connected in series with the circuit.
• NCV Not Working: Ensure the NCV function is selected. The NCV sensor needs to be close to the AC voltagsors e.
