Istruzzjonijiet Operattivi

Operazzjoni Ġenerali:

• Auto-Rang: The meter automatically selects the appropriate measurement range. Press the GANJA button to switch to manual ranging if desired.
• Żamma tad-Data: Agħfas il- ŻOMM buttuna biex tiffriża l-qari attwali fuq id-displej. Agħfas mill-ġdid biex tirrilaxxa.
• Dawl ta' wara: Press the yellow backlight button to illuminate the display for better visibility in low-light conditions. Press again to turn off.
• Mitfi Awtomatiku: Il-miter jintefa awtomatikament wara perjodu ta' inattività biex jikkonserva l-ħajja tal-batterija.

Multimeter Functions:

1. DC Voltage Measurement (=V):
   • Issettja l-iswiċċ li jdur fuq =V pożizzjoni.
   • Connect the red test lead to the positive side of the circuit and the black test lead to the negative side.
   • Aqra d-DC voltagIl-valur fuq il-wiri.
2. AC Voltage Measurement (~V):
   • Issettja l-iswiċċ li jdur fuq ~V pożizzjoni.
   • Qabbad il-wajers tat-test mal-vultaġġ ACtagsors e.
   • Aqra l-AC voltagIl-valur fuq il-wiri.

4. Agħfas il-blu TEST button to initiate the cable test.
5. The display will show the status of each wire pair (1-8 and Shield) indicating: Miftuħa (broken wire), QASIRA (short circuit), MREVERU (reversed pair), MISWIRE (incorrect wiring), or PARI MAQSUM (pairs split between different connectors).
6. For phone cables, the display will indicate RED-TIP u RED-RING status.

Manutenzjoni

Sostituzzjoni tal-batterija:

When the 'Low Battery' indicator appears on the display, replace the batteries as described in the 'Setup' section to ensure accurate measurements and proper operation.

Tindif:

Imsaħ il-marka tal-miterasing b'reklamaramp drapp u deterġent ħafif. Tużax abrażivi jew solventi. Kun żgur li l-miter ikun niexef għalkollox qabel l-użu.

Issolvi l-problemi

• L-ebda Wiri/Il-Miter Mhux Mixgħul: Iċċekkja l-installazzjoni tal-batterija u kun żgur li l-batteriji huma friski.
• Qari mhux eżatt: Ensure the correct function is selected on the rotary switch. Check test lead connections. Replace batteries if the 'Low Battery' indicator is on.
• LAN Test Errors: Ensure both ends of the cable are properly connected. Verify the cable type (RJ45/RJ11) matches the test.
• No NCV Detection: Ensure the rotary switch is set to NCV. The NCV function detects AC voltage; it will not respond to DC voltage.
