Ħażna:

When the meter is not in use for an extended period, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

Issolvi l-problemi

• Il-miter ma jixgħelx: Iċċekkja l-installazzjoni tal-batterija u kun żgur li l-batteriji mhumiex eżawriti. Ibdel jekk meħtieġ.
• Inaccurate or "0000" readings:
  • Ensure test leads are fully seated in the correct input jacks. The meter's warning system should alert you if they are not.
  • Verify the rotary switch is set to the appropriate function and range.
  • Għall-kejl tar-reżistenza, kun żgur li ċ-ċirkwit ma jkunx enerġizzat.
  • If the meter displays "0000" or inconsistent readings, try turning the meter OFF and then ON again to reset it.
  • Check for blown fuses if measuring current.
• L-ebda dawl minn wara: Press the B/L button. If it still doesn't light, check battery level.
• Auto power-off too soon: The auto power-off feature can be disabled (refer to advanced settings in a full manual if available, or typically by holding a specific button during power-on). The meter will beep before shutting off.
