Ar gyfer y rhan fwyaf o fesuriadau (cyf.tage, resistance, capacitance, diode, continuity), connect the test leads:

• Mewnosodwch blwm y prawf coch yn y MEWNBWN jac.
• Rhowch y plwm prawf du i mewn i'r COM soced.

5. Cyfarwyddiadau Gweithredu

5.1 Gweithrediad Cyffredinol

Use the rotary switch to select the desired measurement function. Press the 'SEL' button to cycle through sub-functions if available (e.g., AC/DC for voltage/current, or different units for temperature).

5.2 Mesur AC/DC Cyftage

1. Set the rotary switch to the 'V~' (AC Voltage) neu 'V-' (Cyf. DCtage) sefyllfa.
2. Connect the test leads to the circuit points you wish to measure.
3. Darllenwch y cyftage gwerth ar y sgrin LCD.

5.3 Mesur Cerrynt AC/DC (Clamp Swyddogaeth)

Mae'r clamp function allows for non-contact current measurement on a single conductor.

Figure 3: Using the clamp jaws of the AIOMEST AI-7200B to measure AC current on a single conductor within an electrical panel.

1. Set the rotary switch to the 'A~' (AC Current) or 'A-' (DC Current) position.
2. Agorwch y clamp genau trwy wasgu'r sbardun.
3. Enclose only one conductor with the clamp jaws. Ensure the jaws are fully closed.
4. Darllenwch y gwerth cyfredol ar y sgrin LCD.

5.4 Mesur Gwrthsafiad

1. Set the rotary switch to the 'Ω' (Resistance) position.
2. Connect the test leads across the component to measure its resistance.
3. Darllenwch y gwerth gwrthiant ar y sgrin LCD.

5.5 Mesur Cynhwysedd

1. Gosodwch y switsh cylchdro i'r safle 'F' (Cynhwysedd).
2. Cysylltwch y gwifrau prawf ar draws y cynhwysydd.
3. Darllenwch y gwerth cynhwysedd ar y sgrin LCD.

5.6 Measuring Temperature
