To power on the meter, rotate the function dial from the OFF position to any desired measurement function. To power off, rotate the dial back to the OFF position. The meter features an auto power-off function to conserve battery life after a period of inactivity.

6.2 Għażla tal-Funzjoni

Use the central rotary dial to select the desired measurement function (e.g., V∼, V−, A∼, A−, Ω, Diode/Continuity, CAP, Hz%). Some positions may have multiple functions; press the FUNC buttuna biex tgħaddi minnhom.

6.3 Measuring AC/DC Current (Clamp Xedaq)

1. Rotate the dial to the A∼ (AC Current) or A− (DC Current) position.
2. Agħfas il-grillu tax-xedaq biex tiftaħ il-clamp xedaq.
3. Dawwar konduttur wieħed biss bis-clamp xedaq. Kun żgur li x-xedaq ikun magħluq għalkollox.
4. Read the current value on the LCD. For DC current, observe the polarity indicator.

8 Issolvi l-problemi

If you encounter issues with your MS2115A, refer to the following common problems and solutions:

• Ebda Display: Check if the meter is powered on. Ensure the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
• Qari Skorrett: Verify that the function dial is set to the correct measurement mode. Ensure test leads are properly connected and not damaged. For current measurements, ensure only one conductor is within the clamp jaw. Check battery level.
• Ebda Ħoss ta' Kontinwità: Ensure the meter is in continuity mode. Check if the circuit has very high resistance or is open.
• NCV Mhux Qed Jiskopri: Ensure the meter is in NCV mode. The NCV function detects AC voltage; it will not detect DC voltage. Ensure the sensor area is close enough to the live conductor.
