4. Gosod

4.1 Gosod Batri

1. Ensure the multimeter is turned off and disconnect any test leads.
2. Lleolwch glawr adran y batri ar gefn y multimedr.
3. Dadsgriwiwch y sgriw(iau) cadw a thynnwch y gorchudd.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Rhowch glawr adran y batri yn ôl a'i sicrhau gyda'r sgriw(iau).

4.2 Cysylltu Gwifrau Prawf

Connect the test leads to the appropriate input jacks on the multimeter:

• Mewnosoder y du plwm prawf i mewn i'r COM jac (cyffredin).
• Ar gyfer y rhan fwyaf o fesuriadau (Cyf.tage, Resistance, Diode, Continuity, Temperature, Battery Test), insert the coch plwm prawf i mewn i'r VΩmA jac.
• For high current measurements (up to 10A), insert the coch plwm prawf i mewn i'r 10A jac.

5. Cyfarwyddiadau Gweithredu

Cyn cymryd unrhyw fesuriad, gwnewch yn siŵr bod y gwifrau prawf wedi'u cysylltu'n gywir a bod y switsh cylchdro wedi'i osod i'r swyddogaeth a ddymunir.

5.1 Mesur DC Cyftage (V=)

1. Set the rotary switch to the desired V= range (e.g., 20V for measuring up to 20V DC).
2. Cysylltwch y plwm prawf coch ag ochr bositif (+) y gylched a'r plwm prawf du â'r ochr negatif (-).
3. Darllenwch y cyftage gwerth ar yr arddangosfa.

5.2 Mesur AC Cyftage (V~)

1. Set the rotary switch to the desired V~ range (e.g., 200V for measuring up to 200V AC).
2. Cysylltwch y gwifrau prawf ar draws y cyfaint ACtage ffynhonnell.
3. Darllenwch y cyftage gwerth ar yr arddangosfa.

5.3 Mesur Cerrynt DC (A=)

1. Pwysig: Disconnect power to the circuit before connecting the multimeter in series.
2. Set the rotary switch to the desired A= range (e.g., 200mA or 10A). Remember to move the red lead to the 10A jack for high current.
3. Agorwch y gylched lle mae'r cerrynt i'w fesur.
4. Connect the multimeter in series with the circuit, ensuring the current flows through the multimeter.
5. Rhowch bŵer i'r gylched a darllenwch y gwerth cerrynt ar yr arddangosfa.

5.4 Mesur Gwrthiant (Ω)

1. Pwysig: Gwnewch yn siŵr bod y gylched wedi'i dad-egnïo a bod yr holl gynwysyddion wedi'u rhyddhau cyn mesur gwrthiant.
2. Set the rotary switch to the desired Ω ystod.
3. Cysylltwch y gwifrau prawf ar draws y gydran i'w mesur.
4. Darllenwch y gwerth gwrthiant ar yr arddangosfa.

5.5 Prawf Deuod (→|)

1. Pwysig: Gwnewch yn siŵr bod y deuod wedi'i ddatgysylltu o'r gylched.
2. Gosodwch y switsh cylchdro i'r Prawf Deuod sefyllfa.
3. Cysylltwch y wifren brawf goch â'r anod a'r wifren brawf ddu â chatod y deuod. Bydd yr arddangosfa'n dangos y gyfaint ymlaen.tage gollwng.
4. Gwrthdrowch y gwifrau. Dylai'r arddangosfa ddangos "OL" (Dolen Agored) am ddeuod da.

5.6 Prawf Parhad ())))

1. Pwysig: Gwnewch yn siŵr bod y gylched wedi'i dad-egni.
2. Gosodwch y switsh cylchdro i'r Prawf Parhad sefyllfa.
3. Connect the test leads across the component or wire to be tested.
4. Os yw'r gwrthiant yn is na thua 30Ω, bydd y swnyn yn seinio, gan nodi parhad. Bydd yr arddangosfa hefyd yn dangos gwerth y gwrthiant.

5.7 Battery Test (1.5V/9V)

1. Gosodwch y switsh cylchdro i'r 1.5V or 9V battery test position, corresponding to the battery type.
2. Connect the red test lead to the positive (+) terminal of the battery and the black test lead to the negative (-) terminal.
3. Darllenwch y batri voltage ar yr arddangosfa.

5.8 Dal Data

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function and resume live readings.
